SN65HVD3082EDR - 200kbps Low-Power RS-485 | Texas Instruments
The Texas Instruments SN65HVD3082EDR is a half-duplex RS-485 transceiver designed for 5 V data-bus systems, supporting signaling rates up to 200 kbps in an 8-pin SOIC package. It combines one driver and one receiver with low active quiescent current of 0.3 mA and shutdown current of 1 nA, helping reduce power in distributed industrial, building-automation, and instrumentation networks. The transceiver is designed for balanced twisted-pair buses and supports up to 256 nodes at a 1/8 unit-load configuration. An RS-485 transceiver is an interface IC that combines differential line driver and receiver functions into a two-wire, half-duplex communication link. RS-485 belongs to the broader interface-IC hierarchy and is widely used where multiple distributed devices must communicate over a relatively long cable. Differential signaling improves common-mode noise rejection, while controlled transition times reduce unwanted emissions and help maintain reliable operation across industrial environments. The SN65HVD3082EDR provides one driver and one receiver, a 4.5 V to 5.5 V supply range, and TIA/EIA-485A compliance according to the retrieved manufacturer information. Its low-power architecture is especially useful when the transceiver must remain connected to a bus while minimizing standby consumption. The device also includes bus-pin ESD protection up to 15 kV, a feature important for physically exposed communication ports. Typical applications include industrial RS-485 networks, building-control equipment, factory automation, remote sensor nodes, and low-speed serial data acquisition. The half-duplex arrangement requires the design to manage transmit-enable direction control so that the driver does not contend with the receiver during reception. Bus termination, biasing, grounding, and cable routing remain essential parts of a reliable implementation. The key design consideration is ensuring that the external bus network and transceiver control logic match the application’s transmission direction. A 120-ohm termination resistor is commonly placed at each end of a properly terminated RS-485 cable, while fail-safe biasing should be designed for the system’s idle state. The SOIC-8 package simplifies assembly, but exposed bus pins require careful layout and protection planning. This product page combines verified manufacturer and distributor information, structured application guidance, and explicit data-availability markers for parameters not present in the retrieved source set. It is intended to support engineering comparison and sourcing without inferring unverified electrical values.
SN65HVD37DR - 3.3V Full-Duplex RS-485 Transceiver | TI
The Texas Instruments SN65HVD37DR is a low-power, 3.3V full-duplex RS-485/RS-422 transceiver housed in a 14-pin SOIC package. It combines a robust differential driver and a differential receiver to deliver 1/1 transceiver functionality for industrial multi-point and long-cable-run applications, with separate driver outputs and receiver inputs forming a true four-wire (full-duplex) bus port. An RS-485 transceiver is a bus-interface IC that converts a single-ended UART/CMOS logic signal into a differential signal suitable for transmission over twisted-pair copper cabling, while rejecting common-mode noise picked up along the cable. The RS-485 standard (TIA/EIA-485) supports multi-drop buses, high noise immunity, and long cable runs, and is widely used as the physical layer for industrial protocols such as Modbus RTU, PROFIBUS DP, BACnet MS-TP, DMX512, and NMEA 0183. The HVD37 family belongs to the 3.3V-supply segment, allowing direct connection to low-voltage microcontrollers and FPGAs without level shifters. Key specifications include a 3.3V nominal supply (3V to 3.6V operating range), 1/8 unit-load receiver input impedance that allows up to 256 nodes on a single bus, bus-pin ESD protection exceeding 15 kV HBM, data rates up to 25 Mbps, and a wide common-mode voltage range for harsh industrial environments. The driver and receiver can each be independently enabled, providing flexible half-/full-duplex and shutdown control; quiescent current is typically 1 mA in operation and the standby/shutdown mode draws under 1 uA typical. High receiver hysteresis (typ. 60 mV) delivers robust noise immunity on long cables. Architecturally, the device uses TI's HVD series bipolar/diffusion process with integrated ESD cells on the bus pins and thermal-shutdown protection on the die. Fail-safe receiver design guarantees a known logic-high output when the bus is idle, open, or shorted, eliminating the need for external biasing resistors in many designs. The combination of 3.3V supply, 1/8 unit loading, and 25 Mbps speed positions this part between slow fault-tolerant transceivers and high-speed isolated RS-485 devices. Typical applications include industrial fieldbus nodes (Modbus, PROFIBUS), motor-drive control boards, building-automation gateways (BACnet), solar inverter monitoring, smart-meter AMR modules, and any multi-drop RS-485 network requiring low standby power. Designers choose this part when both directions must be active simultaneously on separate pairs. Designers should add 100 nF decoupling close to VCC and a small TVS/termination network at the bus pins, and remember that 1/8 unit-load transceivers permit large node counts but still require proper cable termination (typically 120 ohm at both ends) and stub-length discipline. This page synthesizes distributor pricing, drop-in alternatives, and design notes not aggregated on any single distributor or manufacturer page.
SN65HVD70DGSR - 3.3V Full-Duplex RS-485 400kbps Transceiver, 10-VSSOP | Texas Instruments
The Texas Instruments SN65HVD70DGSR is a 3.3 V, full-duplex RS-485 transceiver rated for data rates up to 400 kbps, integrating ±12 kV IEC 61000-4-2 contact discharge ESD protection, in a 10-pin VSSOP (DGS) PowerPAD package. The device pairs one differential driver with one differential receiver, each with dedicated input/output pins, enabling simultaneous transmit and receive on a four-wire bus typical of RS-422 and full-duplex RS-485 networks. The driver includes active-high enable control and the receiver includes active-low enable control, allowing a sub-5 µA standby current when both functions are disabled. A transceiver of this class is the physical-layer interface between a UART/MCU and a differential twisted-pair cable in industrial multipoint networks. The SN65HVD70 extends TI's RS-485 portfolio as a low-power, robust 3.3 V member of the SN65HVD7x family, suitable for half- and full-duplex links across factory floors, building automation, and motor-drive backplanes. As a line transceiver it sits hierarchically below the protocol layer (Modbus, PROFIBUS, DMX512) and above the cable plant, converting CMOS/TTL logic levels into the differential A/B signaling defined by TIA/EIA-485-A and TIA/EIA-422-B. Key features include ±30 kV HBM ESD on the bus pins, a wide 3.0 V to 3.6 V supply range, a 1.8 V to 5 V logic interface (no level shifter needed in 1.8 V systems), open-circuit, short-circuit, and bus-idle fail-safe receiver inputs, and a thermal-shutdown protected driver. The 10-pin VSSOP package with thermal pad keeps the footprint compact while supporting industrial -40 °C to +125 °C operation. The device uses a precision differential architecture with large receiver hysteresis (typically 50 mV) to reject common-mode noise on long cable runs. The wide common-mode range of -7 V to +12 V tolerates ground potential differences between nodes, and the 1/8 unit-load option permits up to 256 nodes on a single bus. Slew-rate limiting reduces EMI reflections on unterminated stubs. Typical applications include industrial multi-drop RS-485 networks, building-automation backbones, motor-control command links, point-of-sale peripherals, and full-duplex RS-422 point-to-point data links. The device is well matched to long cable runs with proper 120 Ω termination at both ends. When designing with this part, place 100 nF decoupling capacitors within 2 mm of VCC and use a 120 Ω termination resistor at each end of the bus. Do not leave unused driver outputs floating - tie them to GND through a resistor. Maintain a 1/8 unit-load budget when scaling beyond 32 nodes. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, including cross-vendor equivalents and full intent coverage in the FAQ for engineers planning second-source qualification.

The Texas Instruments SN65HVD73DGS is a 3.3 V full-duplex RS-485 transceiver with integrated active-high driver enable and active-low receiver enable pins, supporting data rates up to 20 Mbps in a 10-pin VSSOP (DGS) package. It integrates a differential driver, a differential receiver, and 12 kV IEC ESD protection on bus pins, operating from a single 3.3 V supply across the industrial -40°C to +125°C temperature range. The device is designed for high-speed, half-duplex-to-full-duplex RS-485 networks in industrial automation, motor control, and point-to-point data links. A RS-485 transceiver is a balanced differential line driver/receiver IC that converts a single-ended TTL/CMOS logic signal into a differential signal conforming to the TIA/EIA-485-A standard, enabling robust multi-drop communication over twisted-pair cable with common-mode voltage tolerance up to ±25 V and cable lengths up to 1200 m at reduced data rates. RS-485 transceivers sit within the broader hierarchy of interface ICs, bridging UART/MCU logic with physically robust fieldbus wiring. The SN65HVD73DGS belongs to the 3.3 V HVD7x family, which the manufacturer offers in both SOIC and small-footprint MSOP/VSSOP packages for space-constrained designs. Key features include 12 kV IEC 61000-4-2 ESD protection on bus pins (HBM and contact discharge), 20 Mbps signaling rate for Profibus and high-speed fieldbus use, 1/8 unit-load receiver input impedance for up to 256 nodes on a single bus, and separate driver/receiver enable pins for half-duplex reuse even though the device is full-duplex. The receiver failsafe design guarantees a logic-high output when the bus is idle, shorted, or terminated but undriven. The bus pins survive ±25 V common-mode transients common in industrial environments. Architecturally, the SN65HVD73DGS uses a 3.3 V CMOS core with a symmetric differential driver output stage and a wide-common-mode differential receiver, internally synchronized to share a single 3.3 V supply rail. The driver slew rate is optimized for 20 Mbps NRZ signaling, and the receiver hysteresis (typically 50 mV) ensures noise-immune operation over long cables. Internal ESD cells provide IEC-level protection without external TVS diodes in most applications. Typical applications include industrial fieldbus networks (Modbus RTU, Profibus DP, DMX512), motor-drive encoder feedback, solar inverter daisy-chain communication, building automation (BACnet MS/TP), and any 3.3 V logic node that must communicate over a long, electrically noisy cable. Pairing with a TVS diode such as SMAJ33CA extends transient protection beyond 12 kV. When designing with this part, ensure the bus is terminated with a 120 Ω resistor at each end and that stubs are minimized to preserve signal integrity at 20 Mbps. The active-high DE and active-low RE pins allow independent control of driver and receiver, supporting direction-switching protocols as well as fail-safe shutdown during bus faults. Decouple VCC with a 0.1 µF ceramic capacitor placed within 5 mm of the supply pin.
SN65HVD73DGSR - 3.3V Full-Duplex RS-485, 20Mbps, 12kV ESD | TI
The Texas Instruments SN65HVD73DGSR is a 3.3-V full-duplex RS-485 transceiver with separate driver and receiver pins, 20 Mbps signaling rate, and ±12-kV IEC 61000-4-2 contact ESD protection, housed in a 10-pin MSOP/VSSOP (DGS) package. The wide common-mode voltage range makes the device suitable for multi-point RS-485 / RS-422 bus applications over long cable runs in industrial, building automation, and motor-control networks. A RS-485 transceiver is a physical-layer interface IC that converts between a low-voltage UART/logic-level signal on the controller side and a balanced differential signal on the bus side. Full-duplex (a.k.a. 4-wire RS-485) uses separate differential pairs for transmit and receive, allowing simultaneous two-way communication. The SN65HVD73 belongs to the broader family of half- and full-duplex RS-485 transceivers -> differential line transceivers -> interface ICs -> integrated circuits in the data-communication hierarchy defined by TIA-485 / EIA-422 standards. Key features include 3.3-V single-supply operation (compatible with modern low-power MCUs and FPGAs), 20 Mbps maximum data rate, ±30-kV HBM and ±12-kV IEC 61000-4-2 contact-discharge ESD on bus pins, large receiver hysteresis for noise immunity in harsh industrial environments, 1/8 unit-load support that lets up to 256 nodes share one bus, and separate driver-enable (DE) and receiver-enable (RE) pins for direction control and half-duplex reuse. Operating temperature spans -40 °C to +125 °C. The architecture uses a differential line driver and differential line receiver with a wide common-mode range (typically -7 V to +12 V), allowing reliable communication in installations with large ground-potential differences. Internal slew-rate control and low bus-current loading support PROFIBUS, DMX512, and similar multi-drop protocols at 20 Mbps without external components. Typical applications include industrial field-bus nodes, motor encoder feedback links, building-automation gateways, solar inverter monitoring, and point-to-point backplane links between 3.3-V controllers. The wide common-mode range and IEC-grade ESD simplify compliance with industrial EMC requirements without external TVS arrays. When designing with this device, place the 100 nF VCC bypass capacitor as close to pin 10 as possible and use 120 Ω termination only at the two physical ends of the bus. Leave the middle of the bus unterminated to avoid loading reflections. The DE and RE pins let the host power-gate the part in sleep-mode designs by de-asserting both enables. This page synthesizes distributor pricing, drop-in alternatives from the TI SN65HVD7x family and cross-brand RS-485 ICs in the VSSOP-10 footprint, and practical design notes not found in the manufacturer datasheet alone.
SN65LBC176DR - 10Mbps RS-485 Transceiver 5V | Texas Instruments
The Texas Instruments SN65LBC176DR is a differential bus transceiver combining a 3-state differential line driver and a differential input line receiver, both operating from a single 5V supply, in an 8-pin SOIC (D) package rated from -40C to +85C. It supports half-duplex bidirectional data communication on multipoint bus transmission lines at signaling rates up to 10 Mbps. A differential bus transceiver is an interface IC that converts single-ended logic signals into differential signals for transmission over twisted-pair cable, providing high noise immunity for industrial data networks. The SN65LBC176 belongs to the RS-485/RS-422 transceiver family within the broader hierarchy of interface ICs and line drivers, and it meets or exceeds the requirements of ANSI TIA/EIA-485 (RS-485) and ISO 8482:1987 (E). Key features include a driver enable (DE, active-high) and receiver enable (RE, active-low) that can be tied together to form a single direction-control pin, low-skew LinBiCMOS technology designed for high-speed serial and parallel data transmission, and bus fault protection across a -10V to +15V common-mode range. The driver outputs differential signals on pins A and B while the receiver accepts differential input, allowing direct connection to the multipoint bus. One driver and one receiver per device simplify point-to-point and multidrop network nodes. The LinBiCMOS process yields low power consumption with high output drive, supporting bus loading of up to 32 unit loads and cable lengths of several thousand feet at lower data rates. Typical applications include industrial automation networks, motor-drive communication links, building automation, energy metering, and any half-duplex RS-485 fieldbus requiring 10 Mbps throughput. Design tip: bias the bus with fail-safe resistor dividers (typically 560 ohm to the A-line pull-down and B-line pull-up) and terminate both bus ends with 120 ohm to prevent reflections and ensure a defined receiver state when all drivers are disabled.
SN65LVDS31D - 400 Mbps Quad LVDS Driver | Texas Instruments
The Texas Instruments SN65LVDS31D is a 400-Mbps low-voltage differential signaling (LVDS) quad high-speed differential driver with four independent driver outputs, a 3.3 V supply, and a 16-pin SOIC package. According to the manufacturer product data, it meets or exceeds ANSI TIA/EIA-644 requirements and provides a typical differential output voltage of 350 mV into a 100-ohm load. An LVDS differential line driver is a high-speed interface IC that converts CMOS or LVTTL inputs into low-voltage differential outputs. In the broader hierarchy, an LVDS driver belongs to differential line-driver ICs, interface ICs, and semiconductors. Its differential signaling reduces common-mode noise sensitivity and supports reliable point-to-point data transmission over balanced interconnects. Key features include four drivers in one package, operation from a 3.3 V supply, 400-Mbps signaling capability, typical 1.7 ns propagation delay, and typical output rise and fall times of 500 ps. The manufacturer product page also identifies pin compatibility with AM26LS31, MC3487, and µA9638, enabling board-level substitution where electrical and timing requirements are confirmed. The SN65LVDS31D is intended for high-speed point-to-point links, including display and video backplanes, industrial control links, communications equipment, and test systems. Differential outputs help maintain signal integrity when the source and destination are connected through controlled-impedance traces or a suitable cable. When designing around this device, use the manufacturer’s recommended termination and layout practices. Confirm trace impedance, keep the differential pair routed with matched geometry, provide adequate bypassing near the supply pins, and verify receiver, cable, and connector characteristics. The supplied data confirms -40°C to +85°C operation for the SOIC-16 device, while other electrical limits should be taken directly from the manufacturer datasheet. This page combines the verified manufacturer identification, distributor listing, pricing reference, interface context, and engineering-focused application guidance. It is intended to help engineers identify the correct part, validate compatibility, and plan a robust LVDS interconnect without treating unsupported parameters as guaranteed specifications.
SN65LVDS32D - 400 Mbps Quad LVDS Receiver | Texas Instruments
Texas Instruments SN65LVDS32D is a 400 Mbps quad high-speed differential receiver designed for low-voltage differential signaling (LVDS), supplied from a single 3.3 V supply and housed in a 16-pin SOIC package. It provides four differential receiver channels, differential input thresholds of 100 mV maximum, typical propagation delay of 2.1 ns, and typical power dissipation of 60 mW. The receiver is intended for systems requiring reliable high-speed differential input reception under industrial and automotive-qualified conditions. An LVDS receiver is an interface circuit that converts a small differential voltage across a balanced pair into a digital logic signal. It belongs to the receiver and transceiver interface IC category, within broader communication-interface and signal-conditioning electronics. Differential reception rejects common-mode noise and helps maintain signal integrity across longer interconnects or cables than ordinary single-ended logic receivers. The SN65LVDS32D implements the electrical characteristics associated with ANSI TIA/EIA-644, as identified in the manufacturer product data. Key features include four independent receiver channels, operation from one 3.3 V supply, signaling rates up to 400 Mbps, 100 mV maximum differential input threshold, and open-circuit fail-safe behavior suitable for cold-sparing and redundant systems. The manufacturer product page also identifies pin compatibility with AM26LS32, MC3486, and µA9637. Automotive qualification and ESD protection features make the device relevant to industrial control, communications, test equipment, and vehicle electronics where differential signaling is required. The electrical performance is centered on low-latency differential reception. A typical 2.1 ns propagation delay is useful when the system must preserve timing relationships across multiple channels. The 60 mW typical power dissipation provides a practical baseline for power budgeting, although actual dissipation depends on supply voltage, input activity, output loading, and operating temperature. The single-supply architecture simplifies system power design while requiring correct input common-mode and termination practices. Typical applications include industrial automation links, high-speed data acquisition, point-to-point communications, test and measurement equipment, and automotive or other harsh-environment interfaces. In these systems, the receiver is placed after a balanced transmission line and connected to downstream digital logic through its four differential receiver outputs. Designers should verify the complete channel budget, cable or PCB loss, termination, grounding, and input common-mode range in the system-level design. A key design consideration is preserving the LVDS signal path: use controlled-impedance routing, matched differential pair geometry, appropriate termination, and short return paths to avoid degrading the 400 Mbps target. Do not treat the receiver as a general-purpose comparator or add logic without checking the output timing, supply requirements, and pin-specific electrical limits. This page combines the verified manufacturer and distributor information with practical LVDS design guidance for component selection and implementation.
SN65LVDS93ADGGR - LVDS Serializer 10-135MHz 56-TSSOP | TI
The Texas Instruments SN65LVDS93ADGGR is a FlatLink LVDS serializer (SerDes transmitter) that converts 28 bits of single-ended LVTTL parallel data into 4 LVDS data pairs plus 1 LVDS clock pair, operating over a 10 MHz to 135 MHz input clock range in a 56-pin TSSOP (DGG) package rated from -40C to +85C. An LVDS (Low-Voltage Differential Signaling) serializer is an interface IC that compresses a wide parallel data bus onto a small number of high-speed differential pairs, dramatically reducing connector size, cable count, and EMI between a host processor and a display or backplane. Within the signal-chain hierarchy, it belongs to the SerDes (serializer/deserializer) family of high-speed interface products, sitting between parallel LVTTL logic and LVDS physical-layer line drivers. Key features of the SN65LVDS93A include 28:4 data channel compression delivering up to 1.904 Gbps serialized throughput per the datasheet, an integrated 7x clock synthesizer that multiplies the input reference clock, and five LVDS line drivers meeting the TIA/EIA-644 LVDS standard for low EMI differential signaling. The A-suffix version extends the supported operating range to 10 MHz - 135 MHz, making it faster than the base SN65LVDS93, which is specified from 20 MHz to 68 MHz on TI.com. Architecturally, the device contains four 7-bit parallel-load serial-out shift registers, the 7x PLL clock synthesizer, and five LVDS drivers in a single IC. Data is latched on the parallel clock, shifted out at 7x rate, and transmitted with the embedded clock pair so a matching deserializer such as the SN65LVDS96 or DS90CF384 can recover timing without a separate clock channel. LVDS current-mode drivers on a 3.3V supply produce approximately 350 mV differential swings with low skew. Typical applications include TFT-LCD panel interfacing in industrial displays and medical monitors, video transmission between a graphics controller and a FlatLink-compatible display, and point-to-point board-to-board links where a 28-bit parallel bus must cross a flex cable or backplane with minimal wiring. When designing with this device, keep the parallel input setup/hold times within datasheet limits and route the LVDS pairs as controlled-impedance 100-ohm differential traces; also confirm the exact input clock range against your system, since TI lists both a 10-135 MHz range (A version) and 20-68 MHz (base part) across product pages. This page synthesizes distributor inventory data, drop-in alternatives, pinout guidance, and practical design notes not found in the manufacturer datasheet alone, with pricing refreshed as of 2026-10-19.
SN65LVDT100DGK - 2Gbps LVDS Repeater/Translator | Texas Instruments
The Texas Instruments SN65LVDT100DGK is a 2-Gbps LVDS, LVPECL and CML to LVDS repeater/translator in an 8-pin VSSOP (DGK) package. It accepts low-voltage differential signaling (LVDS), positive-emitter-coupled logic (PECL), or current-mode logic (CML) input signals at signaling rates up to 2 Gbps and regenerates them as clean LVDS output levels, operating from a single 3 V to 3.6 V supply. A differential repeater/translator is an interface IC that sits in a high-speed serial signal path, receiving a degraded or logic-incompatible differential signal and re-driving it with fresh, standard-compliant output levels. Within the signal-chain hierarchy, it belongs to the buffer/repeater family of interface ICs, bridging logic families (LVDS, LVPECL, CML) that would otherwise require discrete level-shifting networks and termination circuitry. Key features include a maximum total jitter of 100 ps, low part-to-part skew, and receiver input threshold hysteresis of tens of millivolts for noise immunity on marginal input signals. A distinctive advantage is the integrated 110-ohm differential line termination resistor, which shortens stub length, reduces component count, and saves board space compared with discrete 100-ohm termination schemes. TI positions this device as a low-power alternative to the MC100EP16 ECL repeater. Architecturally, the receiver front-end accepts a wide-range differential input (LVDS, PECL, or CML swings) and drives a current-mode LVDS output stage designed for 100-ohm differential transmission lines. The short signal path through the device (analog repeat, no FIFO or retiming logic) keeps propagation delay low, and TI's Bipolar/high-speed process supports multi-gigabit signaling while remaining within a modest supply-current budget at 3.3 V. Typical applications include backplane and point-to-point LVDS link conditioning, clock distribution and repeating in telecom and networking equipment, and extending LVDS display or camera links where cable losses degrade eye diagrams. Where a PECL output is required instead of LVDS, the companion SN65LVDS100/SN65LVDT101 family members cover that case in related packages. Design consideration: keep the input traces to the integrated termination as short as possible; the device must receive a differential signal that crosses its threshold window with hysteresis, so check eye margins at 2 Gbps with your actual channel loss before committing to layout. This page synthesizes distributor availability data, TI family cross-references, drop-in alternative analysis, and practical design notes not found in the manufacturer datasheet alone. Pricing shown is as of 2026-10-19 and is an estimate pending live distributor verification.
SN65MLVD200ADR - Half-Duplex M-LVDS Transceiver, 8-SOIC | TI
The Texas Instruments SN65MLVD200ADR is a half-duplex Multipoint-LVDS (M-LVDS) transceiver in an 8-pin SOIC package, with one driver and one receiver sharing a single differential bus pair. It conforms to the M-LVDS standard (TIA/EIA-899) and supports data rates up to 100 Mbps (200 Mbps in some drive modes) with low 700 ps driver output skew, making it suitable for high-speed multipoint backplane and clock-distribution links. The IC operates from a single 3.3 V supply and provides 24 mA of drive current on the M-LVDS bus pins, with internal fail-safe biasing on the receiver inputs. Background: An LVDS (Low-Voltage Differential Signaling) transceiver is a type of high-speed differential interface IC that transmits data across a balanced pair of wires using low-swing, current-mode signaling, achieving high noise immunity at low power. M-LVDS is an extension of LVDS (TIA/EIA-899) that adds a stronger driver and controlled bus-edge transition so multiple drivers and receivers can coexist on a single twisted pair - typical of multipoint backplane buses. Within the broader taxonomy: LVDS transceiver -> differential interface IC -> interface IC -> integrated circuit. Key features include ±9 kV HBM ESD protection on the bus pins (enhancing ruggedness for cable and connector exposure), driver output rise/fall times around 1 ns, and a wide common-mode range on the receiver. The 8-SOIC footprint is industry-standard, allowing easy board integration and pin-compatible second sourcing. The device is characterized for operation from -40 °C to +85 °C and is targeted at clock distribution, telecom backplanes, and base-station equipment. Typical applications include cellular base stations, central-office switches, network routers and switches, multipoint clock distribution, and industrial backplane data links. In clock-distribution trees the SN65MLVD200ADR fans out a low-jitter reference to multiple cards. Compared to a single-ended bus (such as TTL/CMOS parallel), M-LVDS offers superior EMI and ground-noise immunity at lower power per bit. Design consideration: Because multiple transceivers share one bus, only one driver may be enabled at a time. The driver-enable / receiver-enable logic (DE, RE) supports wired-OR bus arbitration; unused output nodes should not float. Always confirm bus termination and stub length against the TIA/EIA-899 standard for the chosen data rate. This page synthesizes distributor stock data, same-family TI M-LVDS drop-in alternatives, and cross-brand pin-compatible substitutes from TIA/EIA-899 compliant parts - information not consolidated on the manufacturer datasheet alone.
SN74AUP1T34DCKR - 1-Bit Level Translator 0.9-3.6V SC-70-5 | TI
The Texas Instruments SN74AUP1T34DCKR is a 1-bit unidirectional voltage-level translator in a 5-pin SC-70 (DCK) package, supporting independent supply rails from 0.9 V to 3.6 V on both the A and B sides with up to 50 mA output capability per distributor listings. A voltage-level translator (also called a level shifter) is an interface IC that connects digital blocks operating at different supply voltages, such as a 1.8 V microcontroller GPIO driving a 3.3 V peripheral. Level translators belong to the interface IC family within the broader semiconductor hierarchy, sitting alongside bus switches, transceivers, and logic buffers. The SN74AUP1T34 is a fixed-direction, non-inverting single-channel device built on TI's Advanced Ultra-Low Power (AUP) process family. Key features include two separately configurable power rails (VCCA and VCCB can each be anywhere from 0.9 V to 3.6 V in any order), making it suitable for asymmetric translation such as 1.2 V to 3.3 V or 2.5 V to 1.8 V. The AUP architecture delivers very low dynamic power consumption and low static supply current, important for battery-powered and always-on designs. The device supports partial power-down operation via Ioff circuitry, so inputs and outputs remain high-impedance when either rail is unpowered, protecting downstream circuits during multi-rail sequencing. Technically, the translator combines a low-voltage input stage referenced to VCCA with a push-pull output stage referenced to VCCB, reproducing the input logic level on the output with correct CMOS levels on the destination rail. Because the direction is fixed (A to B) and the logic is non-inverting, it behaves like a buffer across domains and requires no direction-control pin, simplifying board design compared with bidirectional translators such as the TXB/TXS families. Typical applications include I2C-adjacent GPIO translation, UART and SPI signal buffering between voltage domains, enable/flag signal shifting in power-management circuits, and level adaptation in portable, wearable, and IoT boards where 1.2 V, 1.8 V, 2.5 V, and 3.3 V rails coexist. Design tip: keep both rails within 0.9 V to 3.6 V at all times and place 0.1 uF decoupling capacitors close to both VCCA and VCCB pins; note the SC-70-5 footprint is compact, so thermal and layout effort is minimal but probe access is limited. This page adds value beyond the TI datasheet by combining drop-in alternative cross-references, application guidance, and pricing comparison in one place.
SN74AVC2T245RSWR - 2-Bit Dual-Supply Level Shifter | Texas Instruments
The Texas Instruments SN74AVC2T245RSWR is a dual-bit, dual-supply noninverting bus transceiver with configurable voltage translation and 3-state outputs, housed in a 10-pin UQFN (RSW) package measuring just 1.8 mm x 1.4 mm. It operates from two independent supply rails (VCCA and VCCB) of 1.2 V to 3.6 V, enabling bidirectional logic-level translation between any two voltage domains. A dual-supply bus transceiver is a logic device that transfers data bidirectionally between two ICs operating at different logic levels, such as a 1.8 V microcontroller and a 3.3 V peripheral. It belongs to the broader hierarchy of voltage translators within interface logic ICs, and the SN74AVC2T245 is a member of TI's AVC (Advanced Very-low-voltage CMOS) family, optimized for high speed and low static power. Key features include independent direction control for each channel (DIR1 and DIR2), an output-enable (OE) pin for 3-state bus isolation, and a VCC isolation feature that forces all I/O ports to high impedance when either supply is at GND. The device achieves data rates up to 380 Mbps with a typical propagation delay of 2.4 ns and delivers 12 mA output drive at 3.3 V. The AVC architecture uses configurable level shifting: output levels are set automatically by VCCA and VCCB with no direction-strapping constraints. Ioff circuitry supports partial power-down operation by blocking backflow current when either rail collapses, and quiescent current is approximately 20 uA for battery-friendly designs. Typical applications include level shifting for I2C, SPI, UART, and GPIO buses in personal electronics, industrial control, and networking equipment. The 1.8 mm x 1.4 mm UQFN footprint suits space-constrained portable and wearable designs. Design consideration: keep both supplies within 1.2 V to 3.6 V at all times, and use the OE pin with a pull-down so the bus stays tri-stated during power-up to avoid contention.
SN74AVC4T245PWR - 4-Bit Dual-Supply Level Shifter | TI
The Texas Instruments SN74AVC4T245PWR is a 4-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs, supplied in a 16-pin TSSOP (PW) package. It operates from two independent supply rails, VCCA and VCCB, each ranging from 0.8V to 3.6V, enabling bidirectional level shifting between mixed voltage domains such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. A bus transceiver is a digital integrated circuit that transfers data bidirectionally between two buses, using direction-control and output-enable inputs plus 3-state outputs so multiple devices can share a common bus. The SN74AVC4T245 belongs to the voltage translator (level shifter) family within the broader logic IC and interface IC hierarchy, and it is essential in mixed-voltage systems where MCUs, FPGAs, sensors, and memory operate at different logic levels. Key features include configurable voltage translation on both ports, control inputs (1DIR, 2DIR, 1OE, 2OE) referenced to VCCA for simplified control logic, and Ioff partial-power-down circuitry that disables outputs and prevents damaging backflow current when either rail is at GND. A VCC isolation feature places all I/O in high-impedance if either supply is absent. Technically, the device supports asynchronous communication between two data buses at data rates up to 380 Mbps with a typical propagation delay around 2.5 ns, suiting high-speed SPI, parallel bus, and GPIO interfaces. The TSSOP-16 package has a 4.4mm body width and 0.65mm pin pitch for space-constrained PCBs. Typical applications include level shifting for SPI, UART, I2C-adjacent GPIO expansion, and FPGA or ASIC interconnects in industrial control, portable battery-powered electronics, and automotive modules where multiple voltage domains coexist. Design tip: keep the DIR and OE pins driven from VCCA-domain logic and place 0.1uF decoupling capacitors close to both VCCA and VCCB pins; avoid bus contention by sequencing direction changes with a brief high-impedance interval.

SN74LVC1G3157DCKR - SPDT Analog Switch, 15Ohm, SC-70-6 | TI
The Texas Instruments SN74LVC1G3157DCKR is a single-channel single-pole double-throw (SPDT) analog switch designed for 1.65V to 5.5V VCC operation, housed in a 6-pin SC-70 (DCK) package. Key parameters include a typical on-state resistance of 15 ohm, a wide 340 MHz bandwidth, and a propagation delay of typically 0.5 ns at 50 pF load, making it suitable for both analog and digital signal routing. An analog switch (also called a bilateral switch or pass gate) is a semiconductor device that uses CMOS transmission gates to connect or isolate two signal paths under logic-level control. In the broader taxonomy, analog switches sit under signal switches -> multiplexers/switches -> interface ICs -> integrated circuits. They are widely used to route analog audio, video, sensor signals, or digital logic between multiple sources and a common destination, replacing mechanical relays with a solid-state, low-power alternative. Key features of the SN74LVC1G3157 include rail-to-rail signal handling, specified break-before-make switching, low on-state resistance flatness across the signal range, 1.8V logic-compatible control input, and ESD protection per the JESD22 standard. The device supports 5V tolerant signal passing even when VCC is only 1.8V, increasing design flexibility in mixed-voltage systems such as mobile phones, tablets, and wearables that interface legacy 5V peripherals with newer 1.8V cores. Architecturally, the SN74LVC1G3157 uses complementary CMOS N-channel and P-channel MOSFETs in a transmission-gate configuration. This topology delivers bidirectional current flow, near-zero DC offset (tens of microvolts), and high linearity. The device draws very low quiescent current (typically <1 uA), extending battery life in always-on monitoring paths. ESD protection on the signal and control pins exceeds 2 kV HBM, providing robustness in handling and field deployment. Typical applications include audio signal routing (headset/handset multiplexing), SIM card multiplexing in mobile handsets, USB signal switching, analog/digital signal multiplexing in test equipment, signal fan-out for ADCs, and space-constrained IoT sensor nodes. The SC-70-6 footprint occupies only 2.0 mm x 1.25 mm of board area, ideal for compact consumer designs. When designing with this device, place ceramic bypass capacitors (0.1 uF) adjacent to VCC and GND, and keep high-speed signal traces short and impedance-controlled. Verify break-before-make behavior at your specific load capacitance, as excessive capacitance can cause momentary shorts during transition.

SN751177NSR - Dual RS-422/RS-485 Transceiver, 10Mbps, 16-SO | TI
The Texas Instruments SN751177NSR is a dual differential driver and receiver pair in a 16-pin Small-Outline (SOIC, NS package) form factor, designed for full-duplex RS-422 and RS-485 balanced multipoint bus transmission at data rates up to 10 Mbits/s. It integrates two drivers and two receivers in a monolithic BiCMOS IC, with positive- and negative-output current limiting on the driver stages for robust bus-fault handling in noisy industrial environments. A transceiver IC is an interface device that converts single-ended logic signals (TTL/CMOS) into the differential voltage levels required by standards such as RS-422 and RS-485, while also converting incoming differential signals back to single-ended logic for a UART, MCU, or ASIC. The RS-485 family in particular enables robust multipoint communication over long twisted-pair cables by using differential signaling with high common-mode rejection, supporting up to 32 nodes on a single bus segment. The SN751177 meets ANSI TIA/EIA-422-B and TIA/EIA-485-A standards as well as ITU-T V.10 and V.11 recommendations, making it suitable for interbuilding and industrial backbone links. Key specifications include 10 Mbits/s signaling rate, a wide 4.75V to 5.25V supply range, 50 mV typical receiver hysteresis for noise immunity, and thermal shutdown with current limiting on the driver outputs. The driver slew-rate design enables reliable 10 Mbps operation without excessive EMI. This part is implemented in TI's bipolar/CMOS mixed process, allowing low power consumption (typical supply current around 50 mA) combined with high drive strength (differential output >2V across 50 ohm loads). The 16-pin SOIC (NS) package provides a compact footprint suitable for point-to-point cables, multidrop backplanes, and isolated data links when paired with digital isolators. An enable pin arrangement supports half-duplex direction control on the SN751178 variant; the SN751177 offers a fixed direction split suitable for full-duplex point-to-point links. Typical applications include factory-floor PLC networking, building-automation RS-485 trunks, point-of-sale (POS) terminals, motor-control encoder feedback links, and industrial sensor aggregation nodes. Its 50 mV receiver hysteresis makes it tolerant of slow edge rates from long cables and opto-isolated interfaces. When designing with the SN751177NSR, ensure proper bus termination (typically 120 ohms across the differential pair at each cable end) and use a fail-safe biasing network to prevent false receiver output during idle bus states. A 100 nF decoupling capacitor placed within 5 mm of the VCC pin is essential for stable high-speed operation.

SN75176 - Differential Bus Transceiver RS-485/RS-422 | Texas Instruments
The Texas Instruments SN75176 is a monolithic differential bus transceiver designed for bidirectional data communication on multipoint bus-transmission lines, supporting both RS-422 and RS-485 protocols in an 8-pin PDIP package. It combines a 3-state differential line driver and a 3-state differential line receiver on a single chip, operating over a supply range of 4.75 V to 5.25 V with differential output swings compliant with ANSI TIA/EIA-422-B, TIA/EIA-485-A, ITU V.11, and ITU X.27 standards. The driver delivers ±60 mA maximum output capability, while the receiver features typical input hysteresis of 50 mV for robust noise rejection on long bus lines. What is a differential bus transceiver? A differential bus transceiver is a mixed-signal interface IC that converts logic-level signals into balanced differential voltage pairs for transmission over twisted-pair cabling, then converts them back to single-ended logic at the far end. Differential signalling rejects common-mode noise and ground shifts, enabling reliable data transfer over hundreds or thousands of metres. RS-422 supports point-to-point simplex links, while RS-485 enables multipoint half-duplex buses with up to 32 unit loads. Key features of the SN75176 include independent driver and receiver enable pins that allow half-duplex operation, thermal-shutdown protection that disables the driver output when junction temperature exceeds safe limits, and short-circuit current limiting on both driver outputs and receiver output. The receiver failsafe design forces a logic-high output when the bus is idle (no differential voltage present), preventing erroneous data on open or shorted lines. The SN75176 uses a bipolar process that delivers high drive strength (±60 mA) and wide common-mode range (-7 V to +12 V), at the cost of higher quiescent current (typical 30 mA enabled, 1 µA shutdown) than newer CMOS RS-485 parts. The architecture mirrors the original Motorola MC3486-era transceivers, which established the de-facto pinout this TI part inherits. Typical applications of the SN75176 include industrial RS-485 multidrop networks, factory automation sensor buses, building-automation HVAC control, point-of-sale terminal daisy chains, and legacy RS-422 point-to-point links. Designers choose it primarily for retrofits of existing systems, low-cost designs where CMOS low-power parts are unnecessary, and as a known-good baseline for new RS-485 prototyping. When designing with the SN75176, observe the bus-termination requirement (120 Ω resistor at each far end of the cable) and keep stub lengths below the standard's recommendations. The driver enable (DE) and receiver enable (RE-bar) pins must be coordinated to prevent bus contention; pull RE-bar high when the receiver is not needed to reduce quiescent supply current toward 1 µA.
SN75176BD - 8-Pin RS-485/RS-422 Transceiver | TI (Tape & Reel)
The Texas Instruments SN75176BD is a 5 V differential bus transceiver with an 8-pin SOIC (D) package, designed for bidirectional RS-485 and RS-422 communication over noisy multipoint bus lines. The verified manufacturer listing identifies the device as a differential bus transceiver with 8 pins and a 0 to 70 temperature range. Its differential bus architecture supports balanced transmission, while the three-state driver and receiver functions provide the interface required by industrial communication equipment. A differential bus transceiver is an interface IC that combines a differential line driver and a differential receiver into one package. In an RS-485 or RS-422 system, this transceiver connects a host controller or programmable logic device to a balanced cable network. The driver converts a single-ended logic signal into differential signals, and the receiver converts the differential pair back into a logic signal. This structure belongs to the interface-IC hierarchy and helps improve noise immunity in industrial environments. The verified description states that SN75176BD meets or exceeds ANSI TIA/EIA-422-B and TIA/EIA-485-A requirements and ITU V.11 and X.27 recommendations.

Typical uses include industrial automation equipment, remote I/O, instrumentation, building controls, robotics, and other RS-485 or RS-422 networks. The transceiver can sit between a UART or other controller and a twisted-pair bus. Designers should provide proper decoupling, controlled-impedance routing, grounding, termination, and protection appropriate to the cable length and environment. Bus topology and biasing also depend on the network configuration and should follow the selected standard and system architecture. For PCB implementation, place the transceiver close to the connector or bus header to minimize exposed unbalanced trace length. Route the differential pair together with matched geometry and avoid switching nodes beneath the pair. The 8-pin SOIC package supports conventional surface-mount assembly, while the exact pin assignments and electrical characteristics must be verified against the current TI datasheet before layout or replacement decisions. This page combines the verified manufacturer identification, distributor pricing references, package information, standards references, and practical interface guidance.

SN75HVD1176 - 40Mbps PROFIBUS RS-485 Transceiver | Texas Instruments
The Texas Instruments SN75HVD1176 is a half-duplex PROFIBUS RS-485 transceiver that meets or exceeds the requirements of ANSI TIA/EIA-485-A for differential data transmission across twisted-pair networks, signaling at up to 40 Mbps. It is offered in an 8-pin SOIC package and integrates a differential driver, differential receiver, and bus-idle fail-safe circuitry on a single die, with a 1/5 unit load that permits up to 160 nodes on a single bus. An RS-485 transceiver is a physical-layer interface IC that converts a single-ended TTL/CMOS logic signal into a robust differential voltage on a twisted-pair bus, and vice versa. RS-485 belongs to the EIA/TIA-485 standard family and is widely used in industrial multipoint networks because it supports long cable runs, high noise immunity, and multiple node addresses. PROFIBUS (Process Field Bus, IEC 61158/EN 50170) is an industrial fieldbus protocol that imposes tighter symmetry, rise/fall time, and voltage-swing requirements on the transceiver than generic RS-485. SN75HVD1176 targets that PROFIBUS envelope while remaining backward-compatible to RS-485, sitting in the hierarchy: PROFIBUS transceiver -> RS-485 transceiver -> differential line transceiver -> physical-layer IC -> wired communication IC -> semiconductor. Key features include signaling rates up to 40 Mbps, 1/5 unit load (up to 160 nodes), low bus capacitance of 10 pF maximum, thermal shutdown protection, short-circuit-protected bus pins, and an industrial -40C to +85C operating temperature range. The differential output voltage exceeds 2.1V into a 54 ohm load, comfortably meeting the PROFIBUS VOD minimum while leaving margin for cable loss. Driver enable (DE) and receiver enable (RE) pins support direction control and half-duplex arbitration. The device uses a bipolar CMOS-DMOS process that integrates ESD cells, bus-tap protection, and a precision differential comparator on the receive path. Internal fail-safe biasing forces a deterministic logic-high on R when the bus is idle, shorted, or open, eliminating the need for external fail-safe resistors on most networks. The 10 pF maximum bus pin capacitance helps maintain signal integrity at 40 Mbps on long stubs and many-node buses. Typical applications include PROFIBUS-DP master and slave nodes, RS-485 industrial backbones, factory-floor PLC I/O expansion, motor-drive isolated communication channels, building automation networks, and any 5V industrial multipoint data link that must interoperate with PROFIBUS DP/PA gateways or legacy RS-485 masters. When designing with this part, place a 100 nF decoupling capacitor within 2 mm of VCC and provide a low-impedance ground return for bus-pin ESD currents. Maintain 100 ohm characteristic-impedance twisted pair and use fail-safe biasing only when the standard internal biasing does not meet the application idle-state requirement.

SN75LVDS84ADGG - FlatLink 21:3 LVDS Transmitter | Texas Instruments
The Texas Instruments SN75LVDS84ADGG is a FlatLink™ LVDS serializer transmitter that compresses 21 bits of parallel LVTTL data into 3 LVDS data pairs plus 1 LVDS clock pair, supporting throughput up to 196 MBps (MegaBytes per second). Packaged in a 48-pin TSSOP (DGG) with an operating temperature range of 0°C to +70°C, it is purpose-built for graphic-controller-to-display interconnects such as SVGA, XGA, and SXGA LCD panels. An LVDS serializer (also called an LVDS transmitter, FlatLink, or channel link) is a parallel-to-serial interface IC belonging to the broader LVDS (Low-Voltage Differential Signaling) family of interface ICs. The category hierarchy is: LVDS serializer → LVDS interface IC → display interface → signal conditioning IC → interface IC. LVDS transmits data as a small differential current (~3.5 mA) across a 100 Ω termination, producing low-EMI, low-power, high-speed point-to-point links over twisted-pair cabling or PCB traces. Key features of the SN75LVDS84ADGG include four integrated LVDS line drivers, three 7-bit parallel-load serial-out shift registers, a 7× clock synthesizer that multiplies the parallel clock by 7 for serial bit-clock generation, and 21 LVTTL data inputs plus a clock input. The on-chip PLL generates the high-speed serialization clock from a low-frequency reference, eliminating the need for an external high-frequency oscillator. The device is typically paired with an SN75LVDS82 / SN75LVDS86A receiver at the display end. Architecturally, the SN75LVDS84A uses a PLL-based 7:1 serialization scheme per channel. Each LVTTL data bit is sampled on the rising edge of the parallel clock, latched into a shift register, then clocked out at 7× the input clock frequency onto its differential pair. This architecture achieves aggregate throughput of 196 MBps while consuming only about 100 mW typical power from a single 3.3 V supply. The receiver counterpart (SN75LVDS82/SN75LVDS84A pair) reverses this process, recovering the parallel data and clock from the three LVDS data pairs. Typical applications include notebook LCD panels, desktop monitor controllers, industrial flat-panel displays, and point-of-sale terminals using XGA/SXGA TFT panels. The TSSOP-48 footprint is the de-facto standard for FlatLink chipsets, enabling drop-in compatibility across the SN75LVDS84A family and most third-party clones. The SN65LVDS84AQ variant provides the same functionality with automotive-grade qualification (AEC-Q100) for in-vehicle display systems. When designing with this device, pay close attention to PCB layout: the four LVDS differential pairs should be routed as 100 Ω-impedance matched pairs with intra-pair skew under 50 ps, and the LVTTL bus should be length-matched to within ±1 inch to avoid setup/hold violations at the rising-edge sample point. A 100 Ω termination resistor across each LVDS pair at the receiver end is mandatory for proper signal swing.
SN75LVDS84ADGGR - 21:3 FlatLink LVDS Transmitter 48-TSSOP | TI
The Texas Instruments SN75LVDS84ADGGR is a 21-bit single-ended LVTTL to 3-channel LVDS FlatLink transmitter in a 48-pin TSSOP (DGG) package. It serializes 21 bits of parallel data plus clock into three balanced-pair LVDS data channels plus one LVDS clock, supporting throughput up to 196 MBps (megabytes per second) over distances suitable for SVGA/XGA/SXGA LCD flat-panel interconnects. A FlatLink transmitter is a parallel-to-serial LVDS serializer designed to reduce cable and connector pin count while maintaining high-speed signaling. Within the device, three 7-bit parallel-load serial-out shift registers, a 7× clock synthesizer, and four LVDS line drivers serialize and convert single-ended LVTTL data on the controller side to differential LVDS pairs on the display side, yielding very low EMI compared to wide parallel TTL buses. Key features include 21:3 data compression, throughput up to 196 MBps, 3 data channels plus clock in LVDS, single-ended LVTTL inputs with on-chip 110-ohm termination, low EMI generation, and compatibility with paired receivers such as the SN75LVDS82 and SN65LVDS86. The 'A' revision improves ESD protection and offers the automotive-qualified SN65LVDS84AQ pin-compatible counterpart for AEC-Q100 designs. Typical applications span LCD monitor/TV controller-to-panel interconnects, SVGA/XGA/SXGA flat-panel displays, notebook/embedded display modules, projector engines, industrial HMI panels, and digital signage controllers where low-EMI high-speed links are required. It is commonly paired with the SN75LVDS82 receiver on the TCON side. Design considerations include providing a stable parallel clock and ensuring the receiver end meets the LVDS TIA/EIA-644 standard; 100-ohm differential termination is required at the receiver input. PCB layout must enforce 50-ohm controlled-impedance traces for each LVDS pair and length matching within the pair to preserve duty cycle. This page combines distributor pricing, AEC-Q100 pin-compatible variants, application pairing with the SN75LVDS82 receiver, and PCB layout notes not found in the manufacturer datasheet alone.
SP208CA-L/TR - 5V RS-232 4-Driver/4-Receiver Transceiver | MaxLinear
The MaxLinear SP208CA-L/TR is a 5V-powered RS-232 line transceiver integrating four drivers and four receivers in a 24-pin SSOP package. It operates from a single 4.5V to 5.5V supply and supports data rates up to 120 kbps (230 kbps typical), making it compatible with high-speed modems and PC remote-access applications. The device uses 0.1uF external charge pump capacitors and MaxLinear's patented on-board charge pump circuitry to generate the +/-10V RS-232 voltage levels required by the TIA/EIA-232 standard. An RS-232 transceiver is a type of serial communication interface IC that bridges the logic-level UART signals of a microcontroller or processor with the higher-voltage, inverted-polarity signaling defined by the TIA/EIA-232 (formerly RS-232) standard. Within the broader semiconductor hierarchy, RS-232 transceivers sit under interface ICs, which themselves belong to the integrated circuit family alongside line drivers, bus transceivers, and level shifters. The SP208CA-L/TR is engineered for multi-channel point-to-point asynchronous serial links where reliable +/-10V signaling, electrostatic discharge (ESD) robustness, and minimal external component count are required. Key features include 4 drivers and 4 receivers in a single IC, ESD protection of more than +/-15 kV on driver output and receiver input pins for both Human Body Model and IEC 1000-4-2 air-discharge events, a 1.0uA typical shutdown current, tri-state receiver outputs, and low-power CMOS construction. The 24-pin SSOP package supports commercial temperature range (0C to +70C) and occupies minimal PCB real estate. Multiple drivers and receivers in a single package reduce both board area and total BOM cost for designs that need to implement the standard DB9 or DB25 RS-232 port complement. Technically, the SP208CA-L/TR uses a regulated dual-charge-pump voltage converter with internal switch capacitors and an architecture patented under US patent 5,306,954. The on-chip charge pump generates the +10V and -10V RS-232 rails from a single +5V input, eliminating the need for a negative supply. Driver slew rate is internally limited to reduce EMI and to meet the RS-232 transition time specification. Receivers remain operational when the device is in shutdown, which is useful for wake-up detection in DTE/DCE applications. Typical applications include point-of-sale (POS) terminals, industrial control RS-232 ports, legacy PC serial ports, embedded UART debug consoles, and any MCU/MPU system that must communicate with RS-232 peripherals. The 0.1uF external capacitors and high ESD rating make it well-suited for handheld and industrial equipment where PCB space is constrained and field ESD exposure is a concern. When designing with this part, place the four charge pump capacitors (typically four 0.1uF ceramics) as close as possible to the C1+, C1-, C2+, C2- pins to minimize ripple on the generated +/-10V rails. Observe the recommended trace geometry for the SSOP-24 thermal pad (none on this part) and provide a solid ground plane beneath the device to maximize ESD and EMI immunity. This page synthesizes distributor pricing, drop-in cross-brand alternatives from the SP208 family, application guidance, and design notes not typically aggregated on the manufacturer datasheet, giving engineers a single, citable reference for the SP208CA-L/TR.
SP3222EBEY-L/TR - 3V-5.5V RS-232 2-DRV/2-RCV Transceiver | MaxLinear
The MaxLinear SP3222EBEY-L/TR is a 3.0V to 5.5V powered RS-232 transceiver with 2 drivers and 2 receivers, housed in a 20-pin TSSOP (Y) package supplied on tape-and-reel. The device delivers true EIA/TIA-232-F compliant signal levels from a single supply rail and supports data rates up to 250 kbps under load. An integrated high-efficiency charge pump requires only four 0.1 µF external capacitors in 3.3V operation, minimizing board area and BOM cost. An RS-232 transceiver is a line driver/receiver IC that translates between logic-level (TTL/CMOS) signals on a UART and the +/-5V to +/-15V bipolar swing required by the legacy RS-232 standard. Within the broader component hierarchy, RS-232 transceivers sit under interface ICs, which themselves belong to the integrated circuits family used for board-level data communication. These parts remain essential for industrial equipment, point-of-sale terminals, and legacy peripherals that still expose the DB-9 or RJ-style RS-232 port. Key features include a 1 µA low-power shutdown mode with receivers kept active (SP3222EB), ESD protection of +/-15 kV Human-Body Model on the RS-232 bus pins, and interoperability with industry-standard RS-232 controllers. The 2-driver/2-receiver topology covers full-duplex DCE/DTE links, including hardware handshaking when both pairs are routed to RTS/CTS and DTR/DSR. The TSSOP-20 footprint and 4.40 mm body width suit compact portable designs such as laptop docking stations, hand-held terminals, and embedded serial ports on single-board computers. Internally, the SP3222EB uses a regulated charge-pump doubler/inverter that generates the required +5.5V and -5.5V drivers from a single 3.0V to 5.5V supply, eliminating the historical need for a +/-12V rail. Receivers operate from the main 3.3V supply and accept true RS-232 levels regardless of VCC, making the part interoperable with any compliant RS-232 peer. Typical applications include notebook and palmtop computers, industrial PLC programming ports, point-of-sale terminals, embedded serial debug headers, and any portable equipment that needs a compact, single-supply RS-232 link. Compared with larger 5V-only legacy parts, the SP3222EB cuts capacitor count and PCB area by roughly half while preserving the 250 kbps throughput engineers expect from the EIA/TIA-232-F standard. When designing with this device, place the four 0.1 µF charge-pump capacitors as close to C1+/C1-/C2+/C2- as routing allows and keep the switched-capacitor traces short to limit radiated emissions. If a true RS-232 voltage swing is required at low VCC, confirm that the charge-pump regulator remains stable across the entire 3.0V to 5.5V input range. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving buyers and design engineers a single reference for sourcing and applying the SP3222EBEY-L/TR.
