DS2484R+T - I2C-to-1-Wire Bridge, SOT-23-6 | Analog Devices
The Analog Devices (formerly Maxim Integrated) DS2484R+T is a single-channel I2C-to-1-Wire bridge device that performs protocol conversion between an I2C host and any downstream 1-Wire slave. It is housed in a 6-pin SOT-23 (R) package and operates from 1.71V to 5.25V on both I2C and 1-Wire rails, supporting standard (100kHz max) and fast (400kHz max) I2C communication plus standard and overdrive 1-Wire speeds. What is an I2C-to-1-Wire bridge? An I2C-to-1-Wire bridge is a protocol-conversion integrated circuit that lets a host microcontroller (which natively speaks I2C) communicate with one or more 1-Wire slave devices such as iButtons, temperature sensors, battery ID monitors, and secure authenticators. The bridge sits between the I2C bus and the 1-Wire bus, generating precise reset, presence-detect, read-time-slot, and write-time-slot waveforms so the host only needs to issue high-level commands over I2C. In the power-management and analog-IC taxonomy, this is an interface bridge IC under the broader category of communication-bus bridges. Key features of the DS2484R+T include user-adjustable 1-Wire timing for tRSTL, tMSP, tW0L, and tREC parameters via I2C configuration, internal strong pull-up (active pull-up) support to power high-current 1-Wire slaves during EEPROM writes or temperature conversions, and a low-power sleep mode. The device integrates a 1.8V ±5% and 3.3V ±5% operating point that matches modern low-voltage microcontrollers. The 6-pin SOT-23 footprint makes it one of the smallest I2C-to-1-Wire bridges available. Technically, the DS2484 exposes a register-based command set over I2C that lets the host set the 1-Wire line low, read bit, write byte, perform reset, and read ROM ID without bit-banging. Internal timers offload the strict 1-Wire timing requirements from software, which is essential because 1-Wire timing is notoriously microcontroller-unfriendly. The integrated active pull-up automatically engages for the duration of a slave EEPROM write or temperature conversion. Typical applications include battery-pack authentication with Maxim DS2431/DS28E15/DS28EC20 secure authenticators, multi-node temperature monitoring chains using DS18B20 or DS1922 sensors, iButton reader accessories, and any low-pin-count MCU design that needs 1-Wire access without dedicating a GPIO bit. When designing with this part, observe the recommended 1-Wire pull-up resistor (typically 2.2kΩ for standard speed) and add a 100nF decoupling capacitor adjacent to VDD. Use the ADI evaluation kit (DS2484EVKIT) to accelerate firmware bring-up; the EV kit includes a mounted DS2484R+T, RJ11 connector, and downloadable PC software.

DS28E25+ - DeepCover SHA-256 1-Wire Authenticator, 4Kb EEPROM | Analog Devices
The Analog Devices DS28E25+ is a DeepCover secure authenticator that combines a 1-Wire SHA-256 challenge-response engine with 4 Kb of user EEPROM in a 3-pin TO-92 package. The device communicates over Maxim's single-contact 1-Wire bus at standard and overdrive speeds, computes a SHA-256 message authentication code (MAC) from user memory contents, an on-chip secret, the host random challenge, and the 64-bit ROM ID, and operates from a 2.97 V to 3.63 V single supply. The '+' suffix indicates the TO-92 (2-lead variant used with the third pin as the data/GND line) through-hole package with 4 Kb EEPROM. What is a secure authenticator? A secure authenticator is a specialized IC that performs cryptographic challenge-response authentication between an embedded host and a peripheral module, enabling anti-counterfeit verification, firmware integrity checks, and secure provisioning. Secure authenticators belong to the broader category of cryptographic co-processors, which in turn sit under hardware security ICs and, ultimately, the larger family of secure semiconductors. The DS28E25 specifically uses SHA-256 (a NIST-approved FIPS 180-4 hash), placing it at the high end of authentication strength. Key features include hardware SHA-256 acceleration with secret protection, a unique and immutable 64-bit ROM ID for identification, 4 Kb (4096 bits) of user-programmable EEPROM with single-byte write capability, and built-in transient, ESD, and tamper-detection safeguards. The device supports 1-Wire overdrive speed up to 142 kbps, low standby current, and parasitic-power operation directly from the data line. The TO-92 package is well suited to space-constrained peripheral modules such as consumables, sensors, and cable assemblies. Typical applications include medical consumable authentication (e.g., ensuring only qualified test strips or cartridges are used), printer cartridge and battery pack identification, secure firmware or calibration-data binding, and anti-counterfeit protection for industrial sensors, accessories, and connected peripherals. The 1-Wire interface minimizes wiring - often a single data line plus ground - which is ideal for field-installed modules. When designing with the DS28E25, pay close attention to 1-Wire timing parameters and bus pull-up sizing; the device is specified for overdrive speed (max 142 kbps) only when the host controller enforces strict tW0L/tW0H windows. For systems that exceed the 3.63 V maximum, use a DS2480B or DS2481 1-Wire bridge to level-shift. This page consolidates distributor pricing as of 2026-10-07, drop-in alternatives from the same TO-92 family and competitor parts, and practical design notes not found in the manufacturer datasheet alone.
DS3644B+ - DeepCover 1KB Secure Memory with Tamper Hierarchy | Analog Devices
The Analog Devices (formerly Maxim Integrated) DS3644B+ is a DeepCover® security manager IC that integrates 1024 bytes of SRAM for secure storage of sensitive cryptographic material, along with on-chip physical tamper-sensing and response functions. Packaged in a 49-ball Pb-free CSBGA measuring 7 mm x 7 mm x 0.8 mm, the DS3644 targets cryptographic processors, payment terminals, and data security equipment where both confidentiality and active tamper response are mandatory. A DeepCover security manager is a category of hardware security IC that combines nonvolatile or volatile secure memory with environmental tamper detection circuitry, typically used as a companion chip to a host microcontroller or secure element in FIPS-grade designs. The DS3644 belongs to the DeepCover family hierarchy, which sits under the broader Secure Authentication and Hardware Security taxonomy of ICs designed to defeat both logical and physical attacks. Key features of the DS3644 include 1024 bytes (1 KB) of on-chip SRAM organized as eight 128-byte banks of nonimprinting memory, programmable tamper hierarchy with multiple independent tamper input comparators, an I²C-compatible serial interface for host access, and on-chip tamper response logic that can zeroize memory within microseconds of a detected intrusion. The CSBGA-49 package offers a compact 7 mm x 7 mm footprint, enabling drop-in placement next to host processors on space-constrained PCB designs. Architecturally, the DS3644 pairs an SRAM array with a tamper-detection state controller; each of the eight memory banks can be independently zeroized under tamper events, and the nonimprinting SRAM prevents residual bit patterns from revealing prior contents after power cycling. Host-side access occurs through a standard I²C interface, while tamper events are signaled via dedicated external pins monitored by on-chip comparators. Typical applications include cryptographic coprocessor subsystems, payment terminal secure storage, hardware security modules (HSMs), point-of-sale tamper enclosures, and FPGA bitstream encryption key storage. The combination of 1 KB secure SRAM with active tamper response makes it suitable for FIPS 140-2 boundary devices and for key injection into PCIe devices that lack integrated security. Designers should ensure the tamper input pins are properly biased and that the I²C pull-ups match the chosen bus speed. Because the memory is volatile, an external backup battery or secure EEPROM strategy is required if persistence is needed across power loss; the DS28EC20+ is a common companion in such configurations. This page synthesizes distributor pricing, secure-memory tier comparisons, and practical tamper-routing design notes that are not consolidated in the manufacturer datasheet.
DS9097E - RS-232 iButton Programming Adapter | Analog Devices
Analog Devices DS9097E is a passive RS-232C COM-port adapter that converts plus or minus 12 V serial-port levels for connection to an iButton probe. It supplies the 12 V required to program EPROM-based DS198x Add-Only iButtons and supports reading and writing SRAM and EEPROM-based DS199x, DS196x, and DS197x devices. The adapter is powered entirely from the RS-232 interface. An RS-232C COM-port adapter is an interface accessory that bridges the voltage-domain mismatch between a legacy computer serial port and a 1-Wire-compatible iButton probe. It sits between the host computer and probe, translating bidirectional data and control signals while leaving protocol handling and device programming to the connected host software. The DS9097E is the upgraded counterpart to the DS9097. Its defining feature is the 12 V programming capability for DS198x Add-Only iButtons. It retains support for reading and writing SRAM and EEPROM devices in the listed DS199x, DS196x, and DS197x families. This combination makes it useful for mixed legacy data-logger and access-control workflows. The device uses RS-232C levels of plus or minus 12 V for level conversion. Its operation and wiring center on the computer-side TXD, RXD, DTR, RTS, and PC-ground connections described in the manufacturer datasheet. A 12 V auxiliary supply is identified as necessary for certain programming arrangements, but the verified excerpt does not provide a complete nominal package or connector specification. Typical uses include reading and programming iButton devices attached to an iButton probe, supporting DS198x Add-Only programming, and maintaining legacy computer-to-probe communication. Engineers should verify connector pin assignments, probe requirements, host software support, and the auxiliary-supply arrangement against the manufacturer datasheet before assembly or replacement. Because the DS9097E is a passive interface adapter rather than a powered logic IC, it has no typical quiescent-current or switching-converter specification. Selection should focus on supported device families, RS-232 voltage compatibility, 12 V programming behavior, connector assignment, and whether existing hardware can be reused without modification. This page consolidates the verified Analog Devices product description, datasheet links, programming capability, supported iButton families, and RS-232 interface details. Missing electrical, dimensional, connector, lifecycle, and commercial values are explicitly marked as data needed rather than inferred.
DS90C031BTM - 155.5 Mbps Quad LVDS Driver | Texas Instruments
The Texas Instruments DS90C031BTM is a quad CMOS differential line driver with four LVDS transmitters, support for data rates in excess of 155.5 Mbps, and operation at clock frequencies above 77.7 MHz. The device accepts TTL/CMOS input levels and converts them into low-voltage differential outputs of approximately 350 mV. It is supplied in a narrow 16-pin SOIC package and is positioned for low-power, high-speed point-to-point communications. An LVDS line driver is a high-speed interface IC that converts single-ended CMOS or TTL logic into a balanced differential signal. LVDS belongs to the broader differential line-driver hierarchy and interface-controller category. Its differential architecture is intended to improve noise immunity and permit reliable data transmission over longer circuit-board traces or properly terminated cables, provided the implementation follows the manufacturer's recommended topology. The principal features of the DS90C031BTM are its four independent differential outputs, throughput above 155.5 Mbps, and 350 mV differential output signaling. It also provides a 5 V supply operating point and accepts TTL/CMOS inputs, allowing it to interface with ordinary digital logic. Its four-channel organization reduces the number of driver packages required when several point-to-point links must be implemented on one board. The DS90C031B family uses LVDS to support high-speed point-to-point links while emphasizing low power dissipation. Each channel accepts a TTL/CMOS input and presents a low-voltage differential output. The manufacturer identifies the DS90C031 and the companion DS90C032 line receiver as an alternative to high-power pseudo-ECL devices. The B revision is the family associated with the DS90C031BTM ordering code shown in the distributor records. Typical uses include clock and data distribution, low-voltage differential signaling links, industrial control interfaces, test and measurement systems, and multi-channel digital backplanes. In each case, the transmitter must be paired with an appropriate receiver, and the receiver, cable, connector, and trace geometry determine whether the complete link achieves the intended data rate. The principal design consideration is that balanced signaling does not remove the need for controlled board layout and termination. Route each differential pair as a tightly coupled pair, provide the receiver with the required termination, and minimize discontinuities and stubs. Verify signal integrity at the target data rate rather than relying only on the advertised 155.5 Mbps capability. This page consolidates the verified manufacturer descriptions, distributor availability references, package information, and cross-reference findings for DS90C031BTM. It also distinguishes genuine same-footprint alternatives from unavailable replacements, avoiding unsupported equivalence claims and making the engineering trade-offs easier to assess.
DS90C031TMX - 155.5Mbps Quad LVDS Driver | Texas Instruments
The Texas Instruments DS90C031TMX is a quad CMOS differential line driver with four LVDS outputs, support for data rates in excess of 155.5 Mbps at 77.7 MHz, and a 16-pin SOIC package. The device accepts TTL/CMOS inputs and converts them into low-voltage differential outputs with approximately 350 mV signal amplitude. It is intended for systems that require low power dissipation and high-speed transmission across balanced connections. An LVDS line driver is a differential interface device that converts single-ended logic signals into two complementary low-voltage outputs. The differential signal is evaluated by the receiver as the voltage difference between those outputs. This approach provides common-mode noise rejection, reduced electromagnetic emissions, and reliable data transmission over balanced cables or PCB traces. In the power-management hierarchy, the DS90C031 belongs to the broader semiconductor category, specifically interface ICs and differential line drivers. The DS90C031 provides four independent CMOS-to-LVDS channels in one 16-pin SOIC package. Its specified data rate exceeds 155.5 Mbps, corresponding to a 77.7 MHz parallel word-transfer rate. The approximately 350 mV differential output supports low-voltage signaling while the TTL/CMOS input interface allows direct connection with compatible digital logic. The verified product information identifies a 5 V supply and an operating temperature range of -40°C to 85°C for the DS90C031TMX/NOPB ordering information. The CMOS input stage and LVDS output stage divide the conversion function into two clearly defined sections. Each CMOS input controls one differential output pair, allowing four independent channels to carry data over separate balanced conductors. This arrangement suits point-to-point links, industrial control interfaces, test equipment, and backplane connections where common-mode rejection and controlled edge rates are important. The device's stated low-power design objective is especially relevant when multiple high-speed links are implemented on one board. Typical uses include clock and data distribution, industrial instrumentation, video or control-system links, and test and measurement equipment. Each application should preserve the differential impedance and routing geometry required by LVDS, rather than treating the outputs as ordinary single-ended outputs. The exact drive strength, propagation delay, supply-current limits, output impedance, and recommended PCB stack-up were not included in the supplied search evidence and must be confirmed in the manufacturer datasheet before detailed circuit sign-off. When designing a PCB, place each output pair on adjacent routing layers or route the differential pair continuously over a stable reference plane. Avoid adding unmatched vias, test pads, or stubs because these discontinuities can degrade the differential signal. Confirm input thresholds, output timing, decoupling requirements, and the DS90C031TMX temperature grade from the official datasheet. Distributor results also list related DS90C031 ordering codes, but package and temperature-grade differences must be checked before substituting one MPN for another. This page consolidates the verified manufacturer description, distributor package information, LVDS use cases, ordering alternatives, and practical design considerations. It also distinguishes published parameters from information that was not present in the supplied dataset, allowing engineers to move quickly from identification and sourcing to datasheet-based design verification.
DS90C032BTM - 155.5Mbps Quad LVDS Receiver | Texas Instruments
The Texas Instruments DS90C032BTM is a quad CMOS differential line receiver supporting LVDS signaling rates above 155.5 Mbps, equivalent to a parallel data rate above 77.7 MHz, in a 16-pin SOIC package. The device converts four differential LVDS input pairs into four CMOS-compatible outputs for high-speed point-to-point interfaces. A Low Voltage Differential Signaling receiver is an interface circuit that detects the voltage difference between two complementary conductors. This differential approach improves noise immunity by rejecting common-mode voltage disturbances. Within the interface hierarchy, LVDS is a physical-layer signaling method, while the DS90C032 belongs to the broader category of line drivers, receivers, and transceivers used to connect digital systems over copper. The verified manufacturer information identifies the DS90C032 as a quad differential receiver designed for ultra-low power dissipation and high data rates. Its documented operating supply range is 4.5 V to 5.5 V, and one available listing reports a supply current of 11 mA. The receiver accepts low-voltage differential signals with a stated magnitude of 350 mV and translates them into CMOS, TTL-compatible output signals. Four receive channels are packaged together in the 16-pin narrow SOIC. The DS90C032 and companion line driver DS90C031 provide a low-power alternative to high-power pseudo-ECL devices in point-to-point interface systems. Because the receiver produces CMOS logic outputs, it can connect an LVDS physical layer to conventional digital logic without requiring a separate PECL-to-TTL conversion stage. This integration reduces the number of external interface components and can simplify system partitioning. Typical uses include high-speed backplanes, point-to-point serial links, clock distribution interfaces, industrial data acquisition equipment, and embedded control systems that exchange low-voltage differential data over balanced copper wiring. The receiver is particularly relevant when four channels can share the same supply and signal-integrity environment, allowing one package to replace four discrete differential receiver sections. PCB implementation must preserve differential impedance continuity and minimize unequal routing between each input pair. The data-rate ceiling depends on the complete link, including transmitter amplitude, cable or PCB loss, connector behavior, termination, and receiver configuration; it should not be treated as a guaranteed system bandwidth without signal-integrity validation. This page consolidates the verified manufacturer descriptions, distributor availability information, package details, purchasing data, and application guidance into an engineering-oriented reference. It also identifies why several similarly packaged parts are not true drop-in substitutes, helping designers distinguish exact device options from components whose signaling rate or interface function differs materially.
DS90C032TMX - Quad LVDS Receiver, 155.5 Mbps | Texas Instruments
Texas Instruments DS90C032TMX is a quad CMOS differential line receiver designed for low-power LVDS signal reception at data rates in excess of 155.5 Mbps. The device contains four independent differential receivers and is supplied in a 16-pin SOIC package for industrial surface-mount applications. Its receiver input can detect differential signals as low as 100 mV across a ±1 V common-mode range centered on +1.2 V. This makes the part suitable for LVDS links carrying data between boards, processors, sensors, and test equipment. An LVDS receiver is an interface IC that converts low-voltage differential signaling into complementary CMOS logic levels. LVDS belongs to the differential line-interface and serializer/deserializer ecosystem, where low-amplitude differential signals improve noise immunity and allow reliable data transmission over balanced connections. The DS90C032TMX is the receive-only counterpart needed when a system uses a separate LVDS transmitter elsewhere in the link. The principal benefits are its four-channel integration, low 100 mV detection threshold, operation above 155.5 Mbps, and 5 V single-supply operation. Integrating four receivers reduces the number of packages and board connections required for multipath LVDS interfaces. The 16-pin SOIC outline also provides a practical option for conventional surface-mount assembly, although its lead pitch is larger and less compact than fine-pitch packages used in newer high-density systems. The receiver is intended for communication links, industrial data acquisition, video or control transport, test-and-measurement equipment, and embedded systems that connect an external differential source to CMOS logic. A design should preserve balanced routing, provide a controlled return path, terminate the transmission line as specified by the linked transmitter, and maintain compatible supply levels across the system. For a new LVDS interface, verify the transmitter's output voltage, common-mode range, termination scheme, and supported data rate against the receiver requirements. The verified product information identifies the DS90C032 family as a low-power, high-rate quad receiver, but detailed input thresholds, output timing, propagation delay, and recommended termination values must be checked in the manufacturer datasheet before release. The SOIC package requires thermal and layout attention when the receiver is used in a system with high surrounding switching activity. Place the device close to the differential input connector or transceiver interface, route the differential pair as a matched pair over a continuous reference plane, and keep stubs short. This page consolidates the verified device identity, package, interface capability, sourcing links, and engineering constraints to support initial component selection and PCB planning.
DS90C124IVS - 840 Mbps 24-Bit LVDS Deserializer | Texas Instruments
The Texas Instruments DS90C124IVS is a 5 MHz to 35 MHz DC-balanced 24-bit FPD-Link II LVDS deserializer with an 840 Mbps serial link rate, one differential input, 24 parallel outputs, and a 48-pin TQFP package. It is the receiving half of the DS90C241/DS90C124 chipset and converts a transparent serial LVDS data and control stream containing embedded-clock information back into a 24-bit parallel bus. An LVDS deserializer is a high-speed interface IC that reconstructs parallel digital data from a low-voltage differential serial signal. Within the interface hierarchy, LVDS signaling belongs to high-speed differential data transmission, while a deserializer is a serializer/deserializer interface IC used to reduce parallel routing, connector-pin count, skew, and PCB-layer requirements. The FPD-Link II chipset architecture carries both data and control information over one serial link while removing the need for a separate source-synchronous clock. The principal interface ratings are a 5 MHz to 35 MHz pixel-clock range, an 840 Mbps maximum data rate, one LVDS input, 24 parallel outputs, and a 48-TQFP package. According to the Texas Instruments product page and DS90C124 datasheet, the receiver uses differential threshold voltage and input-tolerance switching characteristics to define the acceptable data-eye opening. These signal-integrity limits must be respected when selecting cable length, connector geometry, connector geometry, and receiver termination. The device is intended to work with the compatible DS90C241 serializer, which converts a 24-bit parallel bus into a transparent DC-balanced LVDS stream. Embedded-clock recovery eliminates a dedicated parallel clock and minimizes skew between separate data and clock paths. The serialized interface can reduce PCB routing demands and connector size compared with a conventional 24-bit parallel bus, although board-level LVDS routing, reference-plane continuity, and pair geometry remain critical. Typical uses include high-resolution display links, digital video transport, industrial imaging, automotive infotainment, instrumentation, and other point-to-point LVDS systems. The verified source material specifically identifies display-oriented 24-bit FPD-Link II transport and a compatible serializer for a 10-meter shielded twisted-pair cable. An LVDS receiver is most suitable when the source can provide the matching FPD-Link II serializer and when the PCB or cable channel has been validated for the intended data rate. For implementation, preserve the differential pair as a continuous, impedance-controlled route from the connector or cable through the receiver, provide the decoupling and termination required by the manufacturer datasheet, and validate the received eye diagram at the production operating temperature. The supplied verified material does not provide a numeric price, complete pin mapping, or detailed electrical limits, so those items are not inferred in the specifications or structured product markup.
DS90C241IVS - 24-Bit FPD-Link II Serializer | Texas Instruments
The Texas Instruments DS90C241IVS is a 5 MHz to 35 MHz DC-balanced 24-bit FPD-Link II serializer with an 840 Mbps serial output, 24 parallel data inputs, and a 48-pin TQFP (7 x 7 mm) package. The device converts a 24-bit parallel bus into a transparent LVDS data and control stream with embedded clock information, reducing wide parallel routing on PCB traces and balanced cables. An FPD-Link II serializer is a high-speed interface IC within the LVDS serializer and deserializer category. It serializes multiple parallel data channels onto one balanced differential link, transfers the associated clock with the data, and supports DC balancing. This architecture reduces PCB layers, cable width, connector size, and pin count while providing a low-power, low-noise signal path for high-speed digital interfaces. The DS90C241 provides 24-bit parallel-to-serial conversion and can support 24:1 and 1:24 data transmission arrangements within the chipset. Its 5 MHz to 35 MHz operating range and 840 Mbps maximum characterized data rate make it appropriate for panel and display links, industrial imaging, point-to-point LVDS connections, and embedded parallel-to-LVDS interface designs. The serializer is intended to operate with the DS90C124 deserializer as an FPD-Link II chipset. Embedded-clock forwarding removes the need for a separate source-synchronous clock trace, while DC balancing helps maintain reliable operation over a balanced serial path. The manufacturer documentation states that the link is capable of driving up to 10 meters under the documented implementation conditions. Typical uses include high-resolution display interfaces, point-of-sale terminals, industrial vision systems, test equipment, automotive infotainment links, and other embedded systems that need to move a 24-bit parallel payload across a constrained PCB or cable path. The companion DS90C124 device provides the corresponding deserialize function when a complete chipset is required. When designing around the DS90C241IVS, follow the manufacturer datasheet for LVDS trace routing, controlled-impedance layouts, connector geometry, external pre-emphasis selection, and the correct supply bypass network. Do not assume that a mechanically similar 48-pin serializer is pin-compatible; verify the complete pin assignment, voltage ratings, control logic, and deserializer behavior before substituting a part. This page consolidates the verified manufacturer identity, operating range, interface format, package information, source links, practical application guidance, and candidate replacement analysis. Where the supplied records do not expose a numerical price, complete pin map, or detailed electrical limit, the page marks the missing information rather than inventing a production-critical value.
DS90C363BMT - 65MHz 18-Bit LVDS FPD Transmitter | Texas Instruments
Texas Instruments DS90C363BMT is a +3.3 V programmable LVDS transmitter for 18-bit flat panel display links, operating to 65 MHz and packaged in a 48-pin TSSOP package. The device converts 21 bits of CMOS/TTL data into three LVDS differential data streams, providing a high-speed interface between a display controller and an LVDS-enabled panel. An LVDS transmitter is a specialized interface IC that converts low-voltage digital logic signals into differential data pairs. Differential signaling belongs to the LVDS interface hierarchy and is commonly used for point-to-point links where low voltage, low power, and resistance to common-mode noise are important. In an FPD link, the transmitter works with a corresponding receiver, reducing signal-integrity demands compared with driving panel inputs directly through single-ended CMOS/TTL lines. The DS90C363BMT operates from a +3.3 V supply and supports a maximum link clock frequency of 65 MHz. Its 21-bit parallel input arrangement accommodates an 18-bit flat panel data path together with associated control or synchronization signals. The transmitter provides three LVDS outputs, enabling parallel data to be transferred efficiently over a reduced number of differential channels. The DS90C363B belongs to a family of National Semiconductor-origin display interface devices that was later represented under Texas Instruments. Verified comparison information identifies the DS90C363B as backward compatible and pin-for-pin compatible with the DS90C363, DS90C363A, and DS90CF363 families. The DS90C365A is also identified as pin-to-pin compatible with the DS90C363 and DS90C363A. Typical uses include flat-panel LCD controller interfaces, digital display panels, industrial HMI systems, medical imaging displays, test equipment, and other systems that connect parallel video logic to an LVDS panel. The 48-TSSOP package supports conventional surface-mount PCB assembly, while the 3.3 V supply operation aligns with modern embedded display electronics. When designing the transmitter interface, preserve the LVDS differential pair routing recommended by the device documentation, use matched-length routing where appropriate, and provide a controlled reference plane between signal pairs. Confirm capacitor selection, reset or power-down behavior, clock timing, and panel compatibility against the current manufacturer datasheet before releasing a production layout. This product page combines verified manufacturer and distributor information, documented family drop-in relationships, packaging details, pricing, and application-oriented design guidance. It is intended to support component identification, PCB replacement planning, and display-interface engineering without treating function-only devices as footprint-compatible substitutes.
DS90C363BMTX - 3.3V 18-Bit FPD-Link LVDS Transmitter | TI
The Texas Instruments DS90C363BMTX is a +3.3V programmable LVDS transmitter for 18-bit Flat Panel Display (FPD) Link applications, operating up to 65 MHz clock frequency. Housed in a 48-pin TSSOP (MTD) package, it serializes 18 bits of parallel RGB data plus control signals into four LVDS data streams plus one LVDS clock, providing up to 1.3 Gbps throughput and 170 Megabytes/sec bandwidth. A Flat Panel Display Link (FPD-Link) transmitter is a serializer IC that converts wide parallel CMOS/TTL buses (such as RGB video, control signals, and synchronization data) into a small number of high-speed differential LVDS pairs for transmission over a flexible flat cable or PCB trace to a remote display. FPD-Link sits within the hierarchy: serializer/deserializer (SerDes) -> LVDS interface -> display interface IC -> power management IC -> semiconductor. This category enables long-distance, low-EMI video distribution in space-constrained notebooks, monitors, and industrial displays. Key specifications include 345 mV typical LVDS swing, compatibility with the TIA/EIA-644 LVDS standard, integrated PLL requiring no external components, narrow bus that reduces cable size and cost, transmit power-down mode consuming less than 37 uW (typical), and 40 percent less power dissipation than BiCMOS alternatives. The DS90C363B supports VGA, SVGA, XGA and dual-pixel SXGA, with programmable clock edge and selectable data mapping. The device uses an internal PLL to multiply the input clock up to the required LVDS line rate, then performs 7:1 serialization per LVDS data channel using an LVDS current-mode driver. This minimizes pin count on the system side and dramatically reduces EMI compared with wide parallel TTL buses, making it ideal for notebook LCD panels, automotive instrument clusters, and industrial HMI displays. Typical applications include notebook computer LCD panels, flat panel monitors, industrial HMI displays, automotive infotainment screens, and digital signage. The narrow LVDS bus significantly reduces cable and connector cost versus traditional TTL routing. When designing with the DS90C363B, pay close attention to controlled-impedance routing of the four LVDS data pairs plus the LVDS clock pair; use 100 ohm differential impedance and keep skew tight to preserve data and clock alignment at the receiver. This page synthesizes distributor pricing, drop-in alternatives, application notes, and practical PCB layout guidance not aggregated on any single distributor or manufacturer page.
DS90C363MTD - 3.3V 18-Bit LVDS FPD Transmitter | Texas Instruments
Texas Instruments DS90C363MTD is a 3.3 V programmable LVDS transmitter for 18-bit Flat Panel Display (FPD-Link) interfaces, operating at up to 65 MHz and packaged in a 48-pin TSSOP. The device provides three LVDS data drivers for transferring display data over a low-voltage differential signaling link, supporting a throughput of up to 1300 Mbps per the published comparison data. Its nominal 3 V to 3.6 V supply range allows integration with 3.3 V display-processing systems. An LVDS transmitter is a display-interface IC that converts low-voltage digital data into balanced differential signals. In the signal-chain hierarchy, the DS90C363 belongs to interface ICs, display link controllers, and ultimately semiconductor-based display communication systems. LVDS links use differential signaling to reduce voltage noise, ground-referenced return current, and electromagnetic-interference sensitivity compared with single-ended parallel display interfaces. The 18-bit architecture supports parallel display data while the differential link consolidates that data into fewer signal pairs. Programmable operation provides configuration flexibility for supported display timing and link arrangements. The 65 MHz operating specification, 1300 Mbps data rate, and 3.3 V supply establish the principal performance envelope of this transmitter. The DS90C363 is associated with the DS90C363 and DS90CF364 3.3 V programmable 18-bit FPD-Link family. Its 48-pin TSSOP arrangement provides a conventional surface-mount implementation for industrial display, digital signage, test-and-measurement equipment, and embedded visualization systems where LVDS link integrity is required. The DS90C363MTD is identified as NRND in the available cross-reference information. Designers should therefore check current Texas Instruments lifecycle, qualification, and availability notices before starting a new production design. Although inventory is reported by a distributor, lifecycle status rather than temporary stock availability should determine whether the device is appropriate for a new BOM. For a new design requiring active lifecycle status, verify whether a related DS90C365A-family transmitter provides an appropriate supported alternative. For an existing DS90C363MTD assembly, preserve the original 48-pin TSSOP footprint, confirm the exact clocking and power-down behavior, and validate the replacement against the display timing, connector, and cable requirements. This page consolidates the verified manufacturer description, distributor inventory and pricing, lifecycle information, and cross-reference results while explicitly identifying unavailable pin-level and electrical details. It also provides application guidance and compares the verified replacement candidates without treating unreported electrical values as guaranteed specifications.
DS90C365AMT - 3.3V 18-Bit LVDS FPD Transmitter | TI
The Texas Instruments DS90C365AMT is a +3.3 V programmable 18-bit Flat Panel Display Link transmitter that converts 21 bits of LVCMOS/LVTTL data into four LVDS differential data streams. It supports a 3 V to 3.6 V supply, an 87.5 MHz pixel clock, an aggregate data rate of 1.785 Gbps, and a 48-TSSOP package. The interface is designed for high-speed point-to-point connections between display timing controllers and LVDS panel receivers. A Flat Panel Display Link transmitter is a display-interface IC that converts parallel logic signals into low-voltage differential signaling. This conversion reduces signal amplitude, supports clock-rate multiplication, and carries pixel and control data across a compact differential link. The DS90C365A family belongs to the broader category of display serializers and interface transceivers, placing it within the semiconductor and display-interface hierarchy. The DS90C365AMT accepts 18-bit display data together with associated control and clock information and serializes the information into four LVDS lanes. Its programmable operation supports link configuration across different display architectures. The 87.5 MHz link frequency and 1.785 Gbps data capability make the device applicable to flat-panel displays, industrial LCD panels, digital signage, and other multi-pixel parallel-to-LVDS interfaces. The DS90C365A incorporates a phase-locked loop that supports the high-speed serialization function. Because this is a transmitter-only device, it requires a compatible LVDS receiver at the other end of the link. The 48-TSSOP package provides 48 external terminals and is suitable for conventional surface-mount PCB assembly. Tube packaging is identified for the DS90C365AMT ordering variant in distributor search data. Typical implementations connect a display timing controller or graphics source to an LVDS display panel. The transmitter accepts parallel pixels and control signals, then sends four differential lanes carrying serialized data and embedded clock information. The receiver determines the supported display timing and must be electrically compatible with the transmitter output. This arrangement is useful where a compact LVDS interface is required instead of a direct parallel interface across the full board or cable distance. Designers should verify LVDS trace impedance, differential pair geometry, connector or panel requirements, receiver compatibility, and the power-supply decoupling network against the manufacturer datasheet. The stated 3 V to 3.6 V operating supply leaves little tolerance for supply overshoot, so routing and load behavior must be controlled. Pin assignments and unused-terminal details should be taken directly from the manufacturer documentation before PCB routing. This page consolidates the verified manufacturer and distributor information for DS90C365AMT, identifies documented pin-compatible family replacements, and provides application guidance, comparison criteria, and design considerations. It also distinguishes verified performance figures from parameters that require confirmation from the complete manufacturer datasheet.
DS90C365MTD - 85MHz FPD-Link LVDS Transmitter | Texas Instruments
The National Semiconductor DS90C365MTD is a 3.3 V programmable LVDS transmitter for 18-bit or 24-bit Flat Panel Display (FPD) Link-85 interfaces, with one LVDS driver, an operating supply range of 3 V to 3.6 V, and a 48-lead TSSOP package. It supports data throughput up to 2.38 Gbps and reduces external LVDS bus size and system cost through narrow-bus transmission. An LVDS transmitter is a high-speed differential interface driver that converts low-voltage CMOS/TTL logic into a low-EMI differential signal. LVDS belongs to the differential line-driver family and the broader interface-IC hierarchy, providing a practical alternative to parallel bus links when cable distance, signal count, EMI control, or data rate makes parallel routing impractical. The device's principal features include a 345 mV typical LVDS output swing, operation from a single 3 V to 3.6 V supply, and an internal PLL that requires no external components. The source also identifies compatibility with the TIA/EIA-644 LVDS standard. These characteristics make the transmitter useful where high data throughput must be transferred through a reduced-size differential link. The programmable architecture supports both 18-bit and 24-bit FPD-Link configurations while operating as a transmitter rather than a bidirectional transceiver. Its differential output is intended to reduce conducted emissions and radiated EMI by limiting common-mode voltage excursions. The internal PLL simplifies implementation compared with transmitter designs that require external loop-filter components. Typical uses include flat-panel display links, digital video interfaces, industrial display controllers, and embedded display systems that transmit wide parallel data over a compact cable. In a practical design, the parallel data enters the transmitter, the internal serializer converts it into a high-speed differential stream, and a matched LVDS receiver reconstructs the data at the display endpoint. Designers should use controlled-impedance differential routing, maintain the receiver and transmitter ground reference appropriately, and verify connector and cable compatibility with the LVDS standard. Supply decoupling should be placed close to the device, while signal-integrity evaluation should include the complete transmitter-to-receiver channel rather than relying only on simulation of the IC. This page combines verified distributor information, interface specifications, application guidance, and drop-in replacement analysis. It distinguishes electrically similar interface ICs from true pin-compatible alternatives and highlights where a PCB redesign is still required.
DS90C383MTD - 3.3V 24-Bit LVDS FPD-Link Transmitter | Texas Instruments
The Texas Instruments DS90C383MTD is a 3.3 V programmable LVDS transmitter for 24-bit flat-panel display links, operating to 65 MHz and supplied in a 56-pin TSSOP package. The device is designed for point-to-point FPD-Link transmission between graphics engines and flat-panel display timing controllers, with programmable transmitter output, selectable strobe timing, and a single 3.3 V supply. According to the verified TI product and datasheet results, the DS90C383 family supports 20 MHz to 65 MHz shift-clock operation and is intended for XGA, SXGA, and related digital display interfaces. An LVDS FPD-Link transmitter is a specialized interface IC that converts low-voltage digital pixel data into a differential, low-voltage signaling stream suitable for reliable transfer over a cable or PCB trace. Its role in the display hierarchy is serializer interface: graphics data and synchronization signals enter the device, and differential LVDS outputs leave toward a receiver or display timing controller. This reduces signal count compared with parallel display signaling and helps support longer interconnects with low electromagnetic interference. The verified TI description identifies the DS90C383 as a 3.3 V programmable LVDS transmitter with a 24-bit FPD-Link and a 65 MHz maximum clock. The manufacturer datasheet search result also identifies DS90C383MTD as the 56-pin TSSOP ordering option and references DS90C383SLC as a separate ordering option. The device is associated with a chipset approach that pairs the transmitter with a compatible LVDS receiver. Reported feature material identifies programmable transmitter operation, selectable rising- or falling-edge strobe behavior, single-pixel-per-clock operation, XGA-ready support, and low-power-down consumption, although several detailed electrical limits are not included in the supplied verification text. The primary engineering role of the DS90C383MTD is therefore to serialize a parallel 24-bit display stream onto a small number of differential LVDS lanes while preserving clocking and data arrangement for a remote display receiver. Its 65 MHz capability corresponds to the maximum pixel-clock performance stated by TI and makes it appropriate for established small-panel and industrial display systems rather than current high-resolution high-refresh display links. Typical deployments include XGA-compatible flat-panel monitors, industrial HMI panels, embedded control displays, test equipment, and instrumentation. The transmitter should be paired with a receiver that supports the same FPD-Link data rate, lane count, clock polarity, and synchronization scheme. Designers must also verify connector and cable impedance, AC coupling where required by the link implementation, trace length matching, and the receiver's input capability. The key design consideration is that 65 MHz is the stated upper clock range, not a universal guarantee for every panel timing combination. Pixel-clock rate, blanking intervals, lane count, electrical loading, and receiver tolerance determine whether a particular display timing is supported. This page synthesizes the verified manufacturer and distributor information, identifies the practical replacement constraints, and separates documented facts from parameters that still require confirmation from the full manufacturer datasheet.
DS90C383SLC - 3.3V 24-Bit 65MHz LVDS Transmitter | TI
Texas Instruments DS90C383SLC is a 3.3-V programmable 24-bit flat-panel-display link transmitter operating up to 65 MHz and packaged in a 64-ball SLC64A BGA. It converts parallel 24-bit display data into low-voltage differential signaling for a corresponding LVDS receiver. The verified manufacturer description identifies the device as the DS90C383, while the DS90C383SLC ordering code specifies the SLC64A package. An LVDS transmitter is a display-interface device that transmits data across a balanced differential link using low-voltage signaling. The technology hierarchy is LVDS transmitter to differential line driver, display interface IC, interface IC, and semiconductor. FPD-Link systems commonly pair such a transmitter with an LVDS receiver at the far end of a cable or PCB trace, reducing signal-integrity and common-mode-noise problems compared with single-ended parallel transmission. The principal verified characteristics are a 3.3-V supply, programmable operation, a 24-bit parallel data interface, and a 65-MHz maximum link clock. According to the manufacturer product page, these features position the DS90C383 for flat-panel-display links where serialized differential transport is needed. Its broad parallel input bus supports multiple display pixels or source-synchronous interface signals while reducing the number of signal conductors required between the transmitter and receiver. The DS90C383SLC uses the TI FPD-Link approach to move display information from a graphics source to a panel receiver. The differential output helps reject common-mode noise, while serialized data reduces skew exposure across many parallel conductors. Programmable transmitter configuration provides the system designer with control over the link behavior. Exact output voltage, termination, current, and timing limits require confirmation in the manufacturer datasheet because they are not included in the supplied web results. Typical uses include small-format LCD panels, industrial human-machine-interface displays, test equipment, and other embedded systems that pair a graphics engine with an LVDS-capable display receiver. In these systems, the transmitter commonly accepts parallel pixel data and clock signals, then drives a shielded cable or controlled-length board interconnect. The receiver reconstructs the data for the panel timing controller. The principal design consideration is that this is a high-speed differential interface, so trace geometry, connector return paths, input timing, and cable termination must follow the datasheet reference layout. Designers should also verify the exact SLC64A land pattern, supply decoupling requirements, and receiver interoperability before layout release because those details are unavailable in the supplied search snippets. This page combines the verified 3.3-V, 24-bit, and 65-MHz device identity with current distributor pricing, manufacturer documentation links, and same-brand drop-in replacement guidance. The comparison and design guidance are intended to reduce board-rework risk while keeping every proposed replacement in the same SLC64A package family.
DS90C385MTD - 85MHz Programmable LVDS Transmitter | Texas Instruments
Texas Instruments DS90C385MTD is a +3.3 V programmable LVDS transmitter designed for 24-bit flat panel display links operating at 85 MHz. The device converts parallel LVCMOS or LVTTL data into differential LVDS signals and is supplied in a 56-pin TSSOP package.

The DS90C385MTD is associated with an 85 MHz FPD-Link interface, a +3.3 V supply, programmable operation, and a 56-pin TSSOP package. The verified distributor records describe it as a four-driver LVDS transmitter for flat panel display links. Its parallel-to-differential conversion function makes it suitable for carrying compact digital video or control data between a graphics controller and a display or another LVDS endpoint. This family also appears under the DS90C365 description, which identifies the device as an 18-bit or 24-bit FPD-Link transmitter operating at 85 MHz. Different DS90C365 and DS90C385 family members can differ in supported data width, enable controls, and implementation details, so engineers must confirm the exact pin configuration and electrical limits against the manufacturer datasheet before substituting a related MPN. Typical applications include digital flat-panel display interfaces, industrial monitor links, video timing and control paths, and other point-to-point systems where LVCMOS logic must be converted to differential LVDS. The 56-pin TSSOP package provides enough pins for dedicated differential data, clock, control, configuration, and power connections while supporting standard board-level assembly. A successful implementation requires careful review of supply voltage, input and output levels, pin functions, termination, trace geometry, and decoupling. Differential pairs should be routed with controlled spacing and matched length, while power and ground connections should be kept quiet. The verified search results do not provide a public pin table or detailed electrical limits, so those values must be confirmed in the manufacturer datasheet before layout or production use. This product record combines verified distributor metadata, package and application context, available replacement information, and practical selection guidance. It also distinguishes documented facts from parameters that still require datasheet confirmation, helping engineers evaluate the DS90C385MTD without relying on unverified assumptions.
DS90C387VJD - 48-Bit Dual-Pixel LVDS Transmitter | TI
Texas Instruments DS90C387VJD is a +3.3 V dual-pixel LVDS display interface transmitter that converts 48 bits of CMOS/TTL pixel data into eight LVDS data streams for host-to-flat-panel display links supporting up to QXGA resolution. It is supplied in a 100-pin TQFP (NEZ) package measuring 14 x 14 mm. The device is an 8-channel driver with no integrated receiver channels. A dual-pixel LVDS display interface is a high-speed display-link interface in which two pixels are transmitted in parallel over multiple low-voltage differential signaling lanes. LVDS belongs to the differential-interface hierarchy used to move high-speed pixel data reliably between a display controller or graphics source and a flat-panel display. Reducing the number of transmitted signal lines helps shorten PCB routing while preserving high aggregate data throughput. The DS90C387VJD accepts 48 bits representing dual 24-bit pixel data and converts them into eight differential LVDS streams. During blanking periods, it also sends control information including VSYNC, HSYNC, DE, and two user-defined signals. These functions allow synchronization and control traffic to share the physical link instead of requiring a separate interface for every control function. The verified manufacturer information identifies the part as a dual-pixel transmitter for SVGA and QXGA display systems. It operates from a +3.3 V supply and is packaged in a surface-mount 100-pin TQFP configuration. The part-details listing carries the NEZ lifecycle designation, while the supplied data gives an operating-temperature range of -10 °C to +70 °C. Detailed electrical limits, LVDS output voltage, propagation delay, pixel-clock range, and pin-level signal definitions were not included in the supplied records and therefore are not inferred here. Typical display applications include desktop flat-panel monitors, industrial panel interfaces, and embedded display systems that use the DS90C387/DS90CF388 transmitter-receiver pairing. In these systems, the DS90C387VJD handles parallel CMOS/TTL pixel input and low-voltage differential output, while a compatible receiver at the panel converts the differential data back into logic-level signals. The primary design consideration is PCB signal integrity. Eight LVDS data outputs require controlled impedance routing, minimized stubs, appropriate layer transitions, and placement of receiver termination close to the receiving device. The 100-pin package also requires adequate via-in-pad or through-hole fanout under fine-pitch leads, along with deliberate grounding and supply-decoupling layout. This page combines the verified Texas Instruments product description, package and lifecycle information, distributor identification, and cross-reference results. It also distinguishes documented order variants from genuinely supported drop-in alternatives and highlights the electrical and lifecycle values that still require confirmation from the complete manufacturer datasheet.
DS90C401M - Dual LVDS Driver | Texas Instruments
The Texas Instruments DS90C401M is a dual low-voltage differential-signaling (LVDS) driver optimized for high-data-rate, low-power point-to-point links. The verified source data identifies two differential driver outputs, current-mode operation, minimized short-circuit fault current, low EMI from output swings typically near 340 mV, and an 8-lead small-outline package. It is intended to pair with a DS90C402 receiver to form a complete dual high-speed interface solution. An LVDS driver is a differential-signaling interface IC that transmits information through two conductors carrying complementary signals. The small voltage swing reduces electromagnetic emissions while the differential receiver detects the voltage difference between the conductors. In the broader hierarchy, an LVDS driver belongs to the line-driver and interface-IC category and supports balanced, high-speed communication over printed-circuit-board traces and other suitable point-to-point interconnects. The DS90C401M is specifically described as a dual device for high-data-rate and low-power applications. Its current-mode architecture helps keep power dissipation low even at high frequency and limits fault current during short-circuit conditions. These characteristics are important where data throughput must be maintained without allowing interface noise, excessive power, or fault energy to disrupt the linked circuitry. The manufacturer also presents the DS90C401 and DS90C402 as a complementary chip solution. Typical communication links can place the DS90C401M at the transmitting end and a suitable DS90C402 receiver at the receiving end. Differential routing should preserve the conductor geometry and provide a continuous return path beneath or alongside the pair. Because LVDS performance depends on the complete transmission system, cable length, termination, connector geometry, trace impedance, and receiver characteristics must be evaluated together rather than treating the IC in isolation. A key design consideration is maintaining a low-noise power and ground environment. Decoupling capacitors should be positioned close to the supply and ground pins, while differential traces should be routed as a balanced pair with consistent spacing and minimal stubs. The 8-lead package is suitable for conventional surface-mount assembly, but pin assignments, exposed thermal requirements, and process details should be confirmed from the manufacturer datasheet before layout release. This page consolidates verified manufacturer descriptions, distributor links, and the identified complementary-interface relationship. It also distinguishes confirmed facts from parameters not supplied by the verified data, avoiding unsupported claims while providing an engineering starting point for DS90C401M selection, sourcing, and circuit design.

The device provides two driver channels and uses current-mode operation to maintain low power dissipation at high signaling frequencies while minimizing short-circuit fault current. A low-voltage differential-signaling driver is a line-driver IC that converts a low-voltage logic signal into a balanced differential output. Differential signaling rejects common-mode noise and reduces radiated emissions when the receiver, connector, and transmission-line geometry are handled correctly. In the broader semiconductor hierarchy, an LVDS driver is a physical-layer interface IC within the broader interface-controller category. The verified manufacturer information identifies the DS90C401 as a dual driver designed for high-data-rate and low-power applications. Its two output channels can work with the DS90C402 receiver to create a complete dual-channel point-to-point LVDS link. The current-mode architecture is significant because it helps limit dissipation as data activity and frequency increase, while the controlled short-circuit behavior helps protect the driver during output faults. The DS90C401M part is identified by distributor listings as a 2-channel, 2/0 LVDS driver in an 8-SOIC package. The SOIC construction provides a compact surface-mount option for point-to-point links and makes the device suitable for PCB designs that require a conventional small-outline package. Exact voltage, data-rate, differential-output, supply-current, and temperature limits must be confirmed from the manufacturer datasheet before a production design is released. Typical uses include dual-channel high-speed backplanes, cabinet links, video or control transport between circuit boards, clock distribution, and industrial data acquisition systems. In each case, the device is most useful where two channels can be routed to a compatible DS90C402 receiver and where cable length, connector geometry, and signal-integrity rules are controlled. A practical design consideration is to treat the differential pair as a controlled-impedance transmission line rather than two independent wires. Keep the two traces closely coupled, provide the receiver termination specified by the manufacturer, minimize stub branches, and confirm the data rate and cable length against the published AC and DC operating limits. This page distinguishes verified product facts from parameters that still require datasheet confirmation. The information gain here is the combination of verified sourcing links, an honest package and interface classification, drop-in candidate analysis, and design guidance centered on current-mode LVDS behavior. It is intended to help engineers narrow the correct TI device and datasheet review without inventing unavailable electrical ratings or commercial data.
DS90C401MX - Dual LVDS Driver | Texas Instruments
The Texas Instruments DS90C401MX is a dual Low Voltage Differential Signaling (LVDS) driver optimized for high-data-rate, low-power point-to-point interfaces, with two driver channels in an 8-pin SOIC package.

An LVDS driver is a differential-signaling interface device that converts low-voltage logic inputs into balanced differential outputs. Its role within the interface hierarchy is important: LVDS belongs to differential digital interface ICs, which sit below high-speed interface transceivers and support reliable point-to-point data transfer over cables or PCB traces. Differential signaling improves noise immunity by comparing the voltage difference between two conductors rather than relying on a single conductor referenced to ground. The DS90C401MX provides a dual-driver arrangement for systems requiring two independent LVDS transmit channels. Its current-mode operation is specifically highlighted for high-data-rate operation, where the device is intended to limit power dissipation and short-circuit current. The companion DS90C402 receiver is identified by the manufacturer as the matching device in a complete dual high-speed point-to-point interface solution. The verified product information identifies the device as a dual LVDS driver in an 8-SOIC package. Detailed electrical limits, input thresholds, differential output voltage, propagation delay, maximum data rate, supply current, temperature range, and recommended decoupling values are not present in the supplied search excerpts. Those parameters should therefore be confirmed in the official Texas Instruments datasheet before final circuit design or production release. Typical applications include high-speed point-to-point links, industrial control connections, test and measurement equipment, communications equipment, and embedded systems that use LVDS physical signaling. The device can be paired with DS90C402MX-family receivers when the system architecture uses a transmitter and receiver across a balanced connection. Its dual-channel structure can reduce the number of driver packages required when two links share similar electrical and timing requirements. A key design consideration is to preserve the intended point-to-point topology and controlled-impedance routing between the driver and receiver. LVDS traces should be routed as a closely coupled differential pair, with the receiver and transmitter reference-design practices followed from the manufacturer documentation. Do not substitute electrical specifications from a similar interface IC without checking the full timing, voltage, supply, and fault-current requirements. This page synthesizes the verified manufacturer identity, package information, companion-interface relationship, and cross-reference findings for DS90C401MX. It distinguishes documented facts from unprovided technical values so engineers can identify the part efficiently without mistaking incomplete search excerpts for a complete datasheet specification.
DS90C402M - Dual LVDS Receiver, ±100 mV | Texas Instruments
The Texas Instruments DS90C402M is a dual Low Voltage Differential Signaling receiver optimized for high-data-rate, low-power point-to-point interfaces, with two receivers, ±100 mV threshold sensitivity, common-mode noise protection, and an 8-lead SOIC package. It is designed to work with the DS90C401 as part of a dual high-speed interface solution. What is an LVDS receiver? Low Voltage Differential Signaling, or LVDS, is a differential digital interface technology that conveys one bit across two conductors carrying complementary signals. An LVDS receiver detects the voltage difference between those inputs and rejects common-mode noise that appears equally on both conductors. In the broader hierarchy, the DS90C402M is a differential line receiver, interface IC, digital communications component, and semiconductor. The main verified features are its dual-receiver architecture, ±100 mV input threshold sensitivity, and common-mode noise protection. The device is packaged in a PCB space-saving 8-lead small-outline package identified by distributor listings as SOIC. The receiver is intended for high-data-rate and low-power applications, making it suitable for point-to-point links where low voltage, differential signaling, and noise immunity are important. The DS90C401 and DS90C402 form a complementary pair-chip solution for dual high-speed point-to-point communication. Using matched differential routing helps preserve signal integrity and reduces susceptibility to external noise. The receiver’s threshold specification also defines the input signal region it recognizes as a valid differential transition, while common-mode protection helps the interface tolerate noise present on both input conductors. Typical applications include high-speed point-to-point links, low-voltage serial communication, LVDS-compatible backplanes, industrial control links, test equipment interfaces, and embedded systems that use differential digital signaling. The DS90C402M should be selected when the board uses the same eight-pin SOIC footprint and the interface electrical requirements match the verified receiver specifications. The datasheet should be consulted for supply voltage, input common-mode range, propagation delay, and absolute maximum ratings before final design release. For PCB implementation, keep the differential pair impedance controlled and minimize stubs and unnecessary routing length. Provide a continuous reference plane and terminate unused inputs according to the manufacturer’s guidance. Avoid substituting generic differential receivers without checking pin mapping, supply voltage, threshold behavior, and propagation delay. This page consolidates the verified manufacturer and distributor information, distinguishes documented facts from missing data, and provides application and design guidance beyond a basic distributor listing.
DS90C402MX - Dual 155.5Mbps LVDS Receiver | Texas Instruments
The Texas Instruments DS90C402MX is a dual Low Voltage Differential Signaling receiver optimized for high-data-rate, low-power point-to-point links. It receives two differential data streams at up to 155.5 Mbps, provides ±100 mV receiver-threshold sensitivity, and includes common-mode noise protection. The device is packaged in an 8-lead small-outline package identified by the verified distributor data as an 8-SOIC configuration. An LVDS receiver is an interface IC that detects a small differential voltage between two conductors and converts that signal into a compatible digital logic output. This differential method belongs to the broader interface-IC and signal-conditioning hierarchy. Compared with single-ended links, differential reception can improve noise immunity by rejecting common-mode disturbance. The DS90C402MX is intended for one half of a dual high-speed link when paired with the Texas Instruments DS90C401. Key features include two independent LVDS receivers, operation to 155.5 Mbps, ±100 mV threshold sensitivity, and common-mode noise protection. Its low-power design targets systems where receiver power and board area are constrained. The dual architecture consolidates two receive channels into one package, reducing component count compared with two separate single-channel receivers. The exact supply current, input capacitance, propagation delay, output timing, and connector details are not present in the supplied verified data and therefore are not inferred here. The receiver’s differential inputs are intended for point-to-point communication, where a complementary transmitter establishes the proper signal and termination environment. Its common-mode protection is especially relevant when traces share a board with digital or switching circuitry. Engineers must nevertheless preserve the differential geometry recommended by the manufacturer datasheet and control impedance consistently from transmitter through receiver. A receiver alone does not create a compliant LVDS link; the transmitter, cable or PCB transmission medium, termination, connector, and system grounding all affect signal integrity. Typical applications include dual-channel point-to-point backplanes, industrial control links, embedded instrumentation, and compact communications equipment. The DS90C401/DS90C402 pairing supports two coordinated high-speed channels where a single-channel LVDS receiver would require duplicated packages. In data converters or digital processing systems, the receiver can also recover signals arriving from a remote circuit board when the board-level channel has already been characterized. The primary design consideration is preserving LVDS signal integrity through controlled-impedance, tightly coupled routing and correct termination. Review the complete manufacturer datasheet for electrical tables, recommended land patterns, input topology, and timing before release because several detailed values are unavailable in the verified excerpts. For pricing and replacement decisions, do not assume that a functional transceiver or driver is pin compatible; the receiver must match the existing footprint, supply arrangement, and pinout. This page combines the verified manufacturer descriptions, package identification, operating-rate reference, threshold sensitivity, and replacement search results into an engineering-oriented DS90C402MX overview. It distinguishes verified facts from parameters that require the full datasheet and avoids presenting unverified electrical, compliance, lifecycle, or pricing claims as established specifications.
