The verified source data confirms a 7.5 V to 40 V supply range and an operating temperature range of -40 C to +125 C. It combines sensor-interface and local power functions in one device. An IO-Link transceiver is the interface between an industrial sensor or actuator and a point-to-point industrial communications link. The LT3669 provides the physical signaling path while integrating power-conversion functions for the connected equipment. This combination can reduce the number of discrete interface and power-supply components in sensor modules, compact control blocks, and industrial field devices. The LT3669 is designed around three functional blocks identified by Analog Devices: an IO-Link transceiver, a step-down regulator, and an LDO. It also includes wake-up detect functionality and a programmable power-on reset timer. The transmitter current limit and slew rate are externally adjustable, allowing the application to tune communication behavior and power-delivery characteristics. The supplied manufacturer information also identifies the LT3669 family as recommended for new designs. Typical industrial uses include IO-Link sensor interfaces, proximity and limit sensors, industrial actuator modules, factory automation equipment, and embedded control systems that need local power alongside a communications transceiver. The integrated architecture can simplify board partitioning, but each rail and signal path still requires careful decoupling, grounding, protection, and thermal review. The exact output-current, switching-frequency, dropout, and timing limits are not present in the supplied verified excerpts and must be confirmed from the complete manufacturer datasheet before production design. When laying out this QFN device, place input, output, and interface decoupling components close to their associated pins, connect the exposed pad to the appropriate thermal and ground plane, and keep sensitive signal routing away from switching-current paths. Verify wake-up and power-on reset timing with the complete electrical specification. The product is available in a tube package according to the verified distributor listing. This product page combines the verified Analog Devices product information, distributor package and sourcing references, and practical design guidance for engineers evaluating the LT3669 in IO-Link systems.
LT3669IUFD#TRPBF - IO-Link Transceiver with Buck/LDO
The Analog Devices LT3669IUFD#TRPBF is an industrial IO-Link transceiver integrating a step-down switching regulator, a low-dropout linear regulator, wake-up detection, and a programmable power-on reset timer. The device is supplied in a 28-pin QFN exposed-pad package measuring 4 mm by 5 mm, combining sensor-interface and local power functions in one device. An IO-Link transceiver is an interface IC that connects industrial sensors and actuators to a point-to-point communications link. It combines physical-layer signaling with supporting functions that help the connected equipment operate reliably in factory automation, sensors, and industrial control systems. The LT3669 belongs to the transceiver and interface-IC hierarchy, while its integrated regulator sections place it at the intersection of communications, power management, and industrial automation. The verified manufacturer description identifies a single-transmitter, single-receiver industrial interface with an integrated step-down regulator and LDO. Wake-up detect functionality supports sensor activation, while the programmable power-on reset timer provides a defined startup delay. The transmitter current limit and slew rate are externally adjustable, allowing the interface behavior to be matched to the wiring, capacitance, and protection requirements of a particular sensor or actuator. Combining the IO-Link physical interface, switching regulator, and LDO can reduce the number of discrete power-support components in a compact sensor design. It is particularly relevant where a sensor needs both a communication link and local regulated power. The integrated regulators also require careful layout because switching-node, analog-ground, and exposed-pad connections must be managed according to the manufacturer datasheet. Typical uses include industrial proximity and process sensors, actuator modules, factory automation equipment, and IO-Link-compatible control systems. The 28-QFN exposed-pad package supports compact placement but requires a controlled PCB land pattern and adequate thermal copper. Design engineers should verify the complete electrical limits, recommended external components, pin names, and application circuit from the official Analog Devices datasheet before production release. This page consolidates the verified manufacturer and distributor information for the LT3669IUFD#TRPBF, identifies the available family alternatives, and highlights practical package and selection considerations. For pricing, use the listed distributor references as of 2026-10-23 and confirm live stock, lead time, and configuration before purchasing.
LT3669IUFD-2#PBF - 40V IO-Link Transceiver | Analog Devices
The Analog Devices LT3669IUFD-2#PBF is an industrial IO-Link transceiver with an integrated step-down switching regulator and low-dropout regulator, a 7.5V to 40V operating range, and support for load currents up to 300mA, all in a 28-QFN surface-mount package. An IO-Link transceiver is an interface IC that connects sensors and actuators to an industrial point-to-point communication link. It combines physical-layer signaling with device power delivery, allowing one integrated module to handle both command communication and a regulated supply. The IO-Link transceiver category sits below industrial interface ICs, while the integrated switching and linear regulators place this device within broader industrial power-management and sensor-interface systems. The LT3669-2 variant supports a 300mA regulator load, whereas the LT3669 integrates a catch diode for operation up to 100mA and the LT3669-2 requires an external catch diode. Wake-up detection and a programmable power-on reset timer support robust industrial sensor behavior. Adjustable transmitter current limit and slew rate provide additional control over physical-layer signal behavior and system integration. The integrated power architecture reduces the number of separate supply components required by an IO-Link sensor module. Its step-down regulator produces a lower sensor-side voltage from the industrial input rail, while the LDO provides a clean regulated output where required. The manufacturer identifies LT3669 and LT3669-2 as being recommended for new designs, making them relevant to current industrial sensing and factory-automation platforms. Typical uses include proximity sensors, photoelectric sensors, industrial actuator interfaces, factory automation equipment, and IO-Link masters or sensor modules operating from protected industrial supplies. The device is particularly useful when the interface must support communication and regulated sensor power in one compact package. Designers should follow the datasheet exactly for the external catch diode, inductor, capacitors, current-limit setting, slew-rate setting, and wake-up or reset configuration. The external diode and regulator layout directly affect reliability, efficiency, and emissions, so PCB layout should follow the manufacturer’s recommended application circuit rather than relying on generic regulator guidance. This page combines verified manufacturer and distributor information, same-package alternatives, interface distinctions, pricing references, and practical engineering guidance. It also separates verified LT3669-2 facts from specifications that still require direct datasheet confirmation.
LT3669IUFD-2#TRPBF - IO-Link Transceiver | Analog Devices
The Analog Devices LT3669IUFD-2#TRPBF is an industrial IO-Link transceiver integrating one transmitter, one receiver, a step-down switching regulator, and a low-dropout regulator in a 28-pin QFN package. It supports a 7.5 V to 40 V supply range and operates from -40°C to +125°C. The -2 variant supports up to 300 mA step-down load current and requires an external catch diode, while the related LT3669 integrates the catch diode for operation up to 100 mA. An IO-Link transceiver is an industrial sensor-interface device that connects compatible sensors, actuators, and master ports over an IO-Link communication link. In the signal path, the integrated receiver detects and conditions incoming IO-Link data, while the transmitter drives the output. The device also provides wake-up detect functionality and a programmable power-on reset timer, reducing the need for separate interface and supervisory circuitry. The most distinctive feature is integration of an IO-Link transceiver with local power conversion. The step-down regulator supplies a lower-voltage rail for sensor or actuator electronics, while the LDO provides a low-dropout output from that rail. In the LT3669IUFD-2#TRPBF, external rectification is required, and the supported switching-regulator load is up to 300 mA. The transmitter current limit and slew rate are externally adjustable, allowing engineers to tune output behavior for a particular line, load, or electromagnetic-compatibility requirement. Operation from -40°C to +125°C suits industrial automation, factory sensors, actuator nodes, and equipment operating across wide temperature ranges. A 40 V maximum supply also provides headroom above conventional 24 V industrial buses, although system transients still require suitable protection. The 28-QFN exposed-pad package is intended for surface-mount assembly and benefits from a properly designed ground and thermal layout. Design attention should focus on the required external catch diode, regulator compensation or output capacitors specified by the manufacturer, exposed-pad soldering, and IO-Link line protection. Because the -2 and non--2 LT3669 versions differ in their integrated catch-diode arrangement and supported regulator load, verify the exact schematic before substitution. The product page identifies the LT3669-2 as recommended for new designs. This page combines verified manufacturer and distributor information with practical selection guidance, function-level application analysis, and explicit data gaps for unverified electrical details. Engineers should consult the complete manufacturer datasheet before setting operating voltages, timing, compensation, current limits, or protection networks.
LT3960EMSE#PBF - 400kbps I2C-to-CAN Transceiver | Analog Devices
The Analog Devices LT3960EMSE#PBF is a robust 400kbps I2C-to-CAN physical-layer transceiver with one transmitter and one receiver, protected against overvoltage line faults, and supplied in a 10-lead MSOP exposed-pad package. It supports a 60V power-supply range, a selectable internal 3.3V regulator or 5V bus-voltage operation, and extended CAN-compatible common-mode reception. An I2C-to-CAN transceiver is an interface IC that bridges a logic-level I2C connection and a differential, fault-tolerant CAN physical bus. This bridge belongs to the CAN interface hierarchy and allows a single-master I2C bus to communicate across noisy or electrically harsh cable distances where direct I2C wiring would be unsuitable. One LT3960 is normally placed near the I2C master, while another device near the remote CAN endpoint completes the link. Key verified features include communication at up to 400kbps, protection from CAN line overvoltage faults, operation from a 60V power-supply range, and the option to use the internal 3.3V regulator or a 5V bus voltage. The CAN-compatible differential receiver has a common-mode range of ±25V or ±36V depending on VCC. These characteristics support reliable separation between sensitive local electronics and a remote, high-noise bus. The LT3960 converts SCL and SDA activity into equivalent differential CAN-bus behavior while permitting bidirectional communication. Its CAN physical layer is designed for robust links, but system designers must still provide correct termination, grounding, surge protection, and decoupling. The exposed pad improves heat transfer, although actual self-heating depends on supply voltage, bus state, and ambient conditions. Typical uses include industrial remote I2C monitoring, building-control equipment, factory sensor links, test systems, and CAN-connected data-acquisition modules. The LT3960 is particularly useful when an embedded controller has an I2C master port but the system requires a longer, noise-isolated connection to remote equipment. The principal design consideration is preserving interface timing and logic levels across the transceiver pair. Follow the manufacturer data sheet together with the EVAL-LT3960-AZ user guide, and verify that the selected supply and common-mode conditions match the installed system. This page consolidates verified manufacturer information, distributor pricing, sourcing links, and application guidance for engineers evaluating the LT3960EMSE#PBF.
LT3960EMSE#TRPBF - 400kbps I2C-to-CAN Transceiver | ADI
The Analog Devices LT3960EMSE#TRPBF is a 400 kbps I2C-to-CAN physical-layer transceiver with bidirectional data communication, 60 V power-supply range, and a 10-lead MSOP exposed-pad package. It is designed to extend a single-master I2C bus through harsh or noisy environments while preserving communication between SCL and SDA signals. A CAN transceiver is an interface circuit that converts logic-level signals into a physical differential bus and receives bus states back into logic-level signals. The LT3960 uses the CAN physical layer as a rugged transport mechanism for an I2C-style single-master bus. Its protected line-fault inputs, extended common-mode capability, and internal regulator support integration where the I2C master and remote bus-powered nodes are separated by substantial cable distance or electrical noise. Key verified features include operation up to 400 kbps, compatibility with 3.3 V and 5 V systems, protection from overvoltage line faults, and an internal 3.3 V regulator or selectable 5 V bus-voltage operation. Bidirectional communication is permitted, allowing data signals to flow between the host-side interface and the bus-side transceiver. The manufacturer identifies the LT3960EMSE as a 10-lead MSOP package, while the orderable LT3960EMSE#TRPBF suffix identifies the leaded RoHS-compliant packaging configuration. The device is supplied from a single wide-ranging input supply, reducing system power-tree complexity when the interface must operate near higher-voltage industrial or automotive-related equipment. Its physical-layer approach is intended for extending a bus rather than replacing a conventional CAN controller. Designers should account for the MSOP exposed pad, line termination, common-mode environment, cable length, grounding, and the different logic and bus-side voltage domains. Typical applications include industrial sensor links, remote instrumentation, building-automation equipment, noisy factory communication, and embedded systems that need I2C traffic to cross an electrically hostile cable. The verified manufacturer page specifically references the EVAL-LT3960-AZ evaluation circuit, which is useful for validating board routing, bus termination, and system behavior. For PCB design, place the transceiver near the cable connector and preserve a controlled return path to reduce common-mode conversion. Confirm the exposed-pad connection and thermal pad layout against the manufacturer package drawing. Do not substitute a conventional CAN transceiver without checking logic-side voltage, timing, fault behavior, and pin compatibility. This page combines the verified Analog Devices product information with practical interface-design guidance. It distinguishes the LT3960 from ordinary CAN controllers, emphasizes the 400 kbps single-master I2C role, and identifies which electrical details must be confirmed in the datasheet before layout release.
LT3960JMSE#PBF - 400kbps I2C-to-CAN Transceiver | ADI
The Analog Devices LT3960JMSE#PBF is a single I2C-to-CAN physical-layer transceiver supporting I2C communication up to 400 kbps, supplied from a 3.3 V or 5 V range, and packaged in a 10-pin MSOP with exposed pad. It converts one I2C master bus into differential CAN-compatible signaling across a long or noisy interconnect, providing one driver and one receiver. An I2C-to-CAN transceiver is an interface IC that bridges the short-range, controller-oriented I2C bus and the CAN physical layer. It extends a single-master I2C connection through a harness or harsh electrical environment while preserving a familiar logic-side interface. In the system hierarchy, this device is an interface transceiver within CAN interface ICs and broader wired-communication semiconductors. The verified information identifies 400 kbps I2C communication, a 60 V power-supply range, and internal 3.3 V operation. It also confirms protection from overvoltage line faults. The LT3960 family is intended for industrial communication, and the manufacturer states that LT3960J performance is guaranteed from -40°C to 150°C operating junction temperature; the broader datasheet also describes -40°C to 125°C operating-temperature assurance. The receiver is a CAN-compatible differential receiver with a wide common-mode range of plus or minus 25 V or plus or minus 36 V, depending on VCC. In a typical two-device arrangement, one LT3960 is placed near the I2C master and the other near the distant endpoint. This arrangement keeps sensitive logic connections local while using the CAN physical layer for the longer link. Typical uses include industrial sensor links, factory automation equipment, building-control modules, remote I/O nodes, and embedded systems that need an I2C master to communicate across a longer cable. Use the exposed-pad land pattern for thermal and electrical performance, and observe the manufacturer's pin and layout guidance. A key design consideration is that the LT3960 is a transceiver, not a general-purpose CAN controller. The connected microcontroller must generate the appropriate bus behavior and protocol, while the LT3960 provides the physical signaling interface. Verify voltage ratings, termination, grounding, and fault conditions against the manufacturer datasheet. This page combines verified distributor and manufacturer information with package, application, and design guidance intended to support faster sourcing and design review.
LT3960JMSE#TRPBF - 400kbps I2C/CAN Transceiver | Analog
The Analog Devices LT3960JMSE#TRPBF is a half-duplex I2C-to-CAN physical-layer transceiver rated for data rates up to 400 kbps, supplied in a 10-pin MSOP with an exposed pad. It operates from 3.3 V or 5 V, supports I2C communication over harsh or noisy environments, and provides CAN-compatible differential signaling with protection against overvoltage line faults. The part is intended for remote sensing, industrial control, and distributed I2C-to-CAN gateway designs. An I2C-to-CAN transceiver is an interface IC that translates the logic-level clock and data signals of a single-master I2C bus into a differential CAN physical-layer signal. The LT3960 extends that bus beyond a local circuit board, using two devices in a typical system: one connects near the I2C master, while the other provides the remote endpoint. This architecture preserves the familiar I2C host interface while gaining the noise immunity and fault tolerance associated with CAN cabling. Key verified features include operation up to 400 kbps, compatibility with both 3.3 V and 5 V systems, a 60 V power-supply range for the CAN-side protection circuitry, and internal 3.3 V regulation. The receiver has a wide common-mode range of ±25 V or ±36 V depending on VCC. The LT3960 is designed for extended temperature-grade industrial environments; the manufacturer states that LT3960J performance is assured over a -40 °C to 150 °C operating junction range. The exposed-pad MSOP package helps remove heat from the device when the CAN-side dissipation is significant. Placement should keep the transceiver close to the connector or cable entry, while the I2C master and local digital ground connections should remain isolated from the harsher CAN return path as appropriate. CAN termination and common-mode behavior must be evaluated for the complete bus rather than inferred from the IC alone. Typical applications include remote sensor nodes, industrial monitoring links, building-control gateways, actuator networks, and embedded systems that need to extend I2C across a noisy cable. The 400 kbps rate is suitable for moderate-speed control and telemetry traffic, not high-bandwidth data transfer. The device should be selected only when its CAN common-mode, fault-protection, supply, and thermal characteristics match the target bus. The most important design check is system-level compatibility: verify the 3.3 V or 5 V I2C levels, cable length and topology, termination strategy, grounding, and the maximum junction temperature. The LT3960’s protected CAN interface can simplify remote-bus deployment, but it does not eliminate the need for correct bus protection and wiring. This page combines verified manufacturer and distributor information with application guidance, comparison parameters, and practical implementation notes. Pricing and availability references are current only as of 2026-10-23; verify distributor stock and delivery terms before ordering.
LTC1067IGN - Dual Switched-Cap Filter 20kHz | Analog Devices
The Analog Devices LTC1067IGN is a rail-to-rail, very low noise universal dual switched-capacitor filter building block that delivers two independent 2nd-order filter sections with cutoff frequencies up to 20 kHz in a 16-pin SSOP (narrow) package. Each filter section uses external resistors and the internal switched-capacitor architecture to implement low-pass, band-pass, notch, and all-pass responses. The device targets signal-conditioning applications where small footprint, low noise, and high dynamic range are mandatory. What is a switched-capacitor filter? A switched-capacitor filter is an active filter topology that emulates a resistor using a capacitor switched at a clock frequency, allowing precise, monolithic filter implementations without external precision capacitors. Within the broader IC taxonomy, switched-capacitor filters fall under active filters -> analog filters -> signal conditioning -> analog ICs -> semiconductors. They are preferred over continuous-time active filters for applications requiring tight frequency accuracy relative to an external clock. Key features include a clock-to-cutoff ratio of 100:1 (the LTC1067-50 variant uses 50:1), rail-to-rail input and output swing that maximizes dynamic range on low-voltage supplies, 60 dB signal-to-noise ratio, and a low noise floor suitable for instrumentation-grade signal chains. Each second-order block uses five external resistors, allowing independent configuration as a low-pass, high-pass, band-pass, or notch stage. Two blocks can be cascaded externally to build a 4th-order filter. The architecture is built on Analog Devices' precision switched-capacitor technology with CMOS analog switches and on-chip clock generation. The clock input accepts a TTL or CMOS external source, and the internal master clock divider sets the filter cutoff, simplifying design-in when synchronization to a system clock is required. The dual-block topology also enables independent filtering of two channels, such as stereo audio or dual-axis sensor signals, in a single IC. Typical applications include antialiasing filters for 16-bit ADCs, smoothing filters for DAC outputs, dual-channel audio crossover networks, instrumentation low-pass filters in data acquisition systems, and ultrasonic transducer front-end filtering in medical imaging. The wide dynamic range makes the LTC1067IGN particularly attractive when the upstream signal already spans most of the supply range. When designing with this part, plan clock-to-cutoff ratio carefully: the cutoff frequency equals fCLK/100 (or /50 for the -50 variant). A stable, low-jitter clock is essential - phase noise on the clock translates directly into passband distortion. Keep clock traces short and away from analog signal traces to prevent coupling. This page synthesizes distributor pricing, pin-compatible drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet's typical application circuits.
LTC202CJ - Micropower Quad CMOS Analog Switch | Analog Devices
The Analog Devices LTC202CJ is a micropower, low-charge-injection quad CMOS analog switch packaged in a 16-pin CERDIP. The device is designed for low-power signal routing and supports single or positive-and-negative supply operation. Its four independently controlled switches support analog multiplexing, demultiplexing, sampling, and signal-routing systems where low power consumption and controlled switching behavior are important. What is an analog switch? An analog switch is an integrated semiconductor switch that routes electrical signals between terminals under digital control. A quad CMOS analog switch contains four switch elements, generally allowing several analog sources to be selected or routed to a common output. The LTC202CJ belongs to the analog-switch hierarchy, which includes multiplexers, demultiplexers, and interface ICs used to connect sensors, converters, test equipment, and other signal-chain circuits. According to the manufacturer product page and identified datasheet family, key features include micropower operation, low charge injection, low on-resistance, low leakage, guaranteed break-before-make behavior, and a latch-resistant design. These characteristics make the device suitable for precision analog systems where switching transients, signal attenuation, and power consumption can affect measurement quality. The available data also identifies the LTC202 as a quad CMOS analog-switch family; exact electrical limits and temperature-grade details require the manufacturer datasheet. The CJ package suffix denotes the 16-pin CERDIP package identified in the verified distributor data. Ceramic-DIP construction is commonly used where temperature robustness, mechanical reliability, or legacy industrial and military compatibility matters. The package requires through-hole board layout rather than a surface-mount footprint, so designers should confirm PCB compatibility before substituting or upgrading this part. Typical applications include precision signal selection, instrumentation multiplexing, test and measurement systems, data-acquisition front ends, sample-and-hold signal paths, and low-power analog control systems. The low charge injection helps reduce switching errors in sampled signals, while the low-leakage characteristic supports preserving small signal levels between selection events. For new designs, engineers should verify absolute maximum ratings, recommended supply voltages, on-resistance, charge injection, leakage current, switching time, and electrical performance across temperature using the manufacturer datasheet. A footprint-compatible replacement must also preserve the 16-pin CERDIP pinout and the same enable and control logic. This page summarizes verified distributor and manufacturer information and separates confirmed facts from parameters requiring datasheet review.
LTC221CJ - Micropower Quad CMOS Switch | Analog Devices
The Analog Devices LTC221CJ is a micropower, low-charge-injection, quad CMOS analog switch with onboard data latches, supplied in a 16-CDIP package. It typically dissipates 250 uW from ±15 V supplies and 40 uW from a single 5 V supply. Each device provides four independently latched analog switches, a 65 ohm typical on-resistance, very high off-resistance, and break-before-make switching. These characteristics suit precision signal routing where low power, controlled switching transitions, and direct microprocessor-bus interface matter. An analog switch is a voltage-controlled semiconductor device that routes analog signals between external terminals. The CMOS implementation combines low leakage with nearly symmetric signal behavior, while the data latches retain switch states and reduce external control-line requirements. In the signal-chain hierarchy, the LTC221CJ belongs to the analog-switch and multiplexer class within integrated interface and switching ICs. Verified features include quad CMOS switch architecture, low charge injection, a 65 ohm typical on resistance, very high off resistance, and inherent break-before-make behavior. The onboard latches allow connection to many microprocessor buses. Its micropower operation is particularly useful in battery-powered instrumentation, automated test equipment, data-acquisition systems, and low-leakage measurement front ends where continuously powered switches can dominate standby power. The LTC221CJ supports both bipolar and single-supply operation, as demonstrated by the documented 40 uW dissipation from 5 V and 250 uW from ±15 V. That operating flexibility lets it sit between grounded or bipolar instrumentation and single-rail data-acquisition systems. Exact supply limits, channel capacitance, leakage, charge-injection values, switching times, latch-control levels, and temperature limits are not present in the supplied search data and therefore require confirmation from the manufacturer datasheet before release to production. Typical applications include multiplexed sensor acquisition, programmable gain or filter routing, instrumentation signal switching, automated test equipment, data loggers, and low-power measurement systems. Route only signals within the verified electrical limits, and account for injected charge when sampling sensitive nodes. Because the search evidence does not expose the full pinout, alternatives, or validated cross-references, production substitution must be based on a package and pin-level review rather than functional similarity alone. Place the device near the routed analog signals and keep control traces away from sensitive switch nodes. Use a ground plane and minimize long traces to reduce capacitive coupling and switching transients. Confirm the power architecture, control logic, and package thermal behavior in the datasheet; this page does not infer values that were absent from the verified sources. This product record combines the supplied manufacturer and distributor evidence, documented power and resistance characteristics, application guidance, and explicit validation boundaries. It distinguishes verified data from parameters still requiring datasheet review, avoiding unsupported substitutes while providing practical context for engineers evaluating the LTC221CJ.
LTC2846IG - 3.3V Multiprotocol Transceiver w/ Termination | Analog Devices
The Analog Devices LTC2846IG is a 3-driver/3-receiver multiprotocol transceiver with on-chip cable termination, housed in a 36-pin SSOP (Industrial Grade) package. Operating from a single 3.3V supply, it supports software-selectable protocols including RS232, RS449, EIA530, EIA530-A, V.35, V.36 and X.21, with a 1ku list price starting from $19.21 as of 2026-10-08. An RS-232/RS-422/RS-485 multiprotocol transceiver is a single-chip interface IC that combines multiple line-driver and receiver channels, allowing one hardware design to be reconfigured in software between legacy serial standards. The transceiver family (LTC2844/LTC2845/LTC2846) is typically deployed in DTE or DCE serial port designs where a single physical connector must handshake with many types of legacy equipment, and on-chip termination removes the need for external resistor networks on V.35/V.36/X.21 lines. Key features include 3 drivers and 3 receivers, on-chip cable termination resistors, software-selectable protocol mode via logic pins, integrated 1.2MHz boost switching regulator that converts the 3.3V supply to 5V for V.35/V.36/X.21 driver levels, and TUV Rheinland NET1/NET2/TBR2 certification. The Industrial Grade (-40C to +85C) temperature rating supports telecom and industrial environments, while the SSOP-36 footprint integrates easily into legacy backplane designs. The architecture combines a digital mode-control block, an on-chip boost regulator (1.2MHz), six terminated line drivers/receivers, and charge pumps for RS-232 compliance. This integration reduces the typical discrete BOM of a multiprotocol port from ~40 components to a single IC plus a few passive components. Typical applications include multiprotocol serial ports in WAN routers, telecom DSU/CSU equipment, V.35/V.36/X.21 line cards, industrial serial gateways, and legacy-to-modern serial protocol converters. When paired with the LTC2844 (clock/data transceiver) or LTC2845 (control-signal transceiver) it forms a complete software-selectable DTE/DCE port. For design, ensure the MODE_SELECT pins are driven through low-capacitance logic and that the boost regulator output (V+ pin) is bypassed with at least 10uF ceramic + low-ESR electrolytic to meet V.35 driver rise/fall time specifications.
LTC2850HMS8#TRPBF - 3.3V 20Mbps RS485/RS422 Transceiver | ADI
The Analog Devices LTC2850HMS8#TRPBF is a low-power 3.3V RS485/RS422 transceiver in an 8-pin MSOP package, supporting data rates up to 20 Mbps with half-duplex (1 driver / 1 receiver) operation. The receiver offers one-eighth unit load, enabling up to 256 nodes on a single bus (C-, I-grade), and integrates a failsafe feature that guarantees a logic-high output under floating or shorted input conditions. The driver maintains high output impedance across the entire common-mode range when disabled, ensuring robust multi-node bus behavior. An RS485/RS422 transceiver is a physical-layer interface IC that converts between the differential signaling used on industrial twisted-pair buses and the single-ended logic levels used by UARTs, MCUs, and FPGAs. RS485 supports multipoint half/full-duplex buses over long distances (up to 1200 m), while RS422 is typically point-to-point. The LTC2850 belongs to the broader line transceivers -> interface ICs -> integrated circuits taxonomy and is part of the LTC2850/LTC2851/LTC2852 family from Analog Devices (formerly Linear Technology). Key features include ±15 kV ESD protection on the bus pins (H-grade designation), thermal shutdown, short-circuit protection, and a wide common-mode range that exceeds the RS485 standard requirement. The H-suffix variant specifies the high-ESD rating and the -40 °C to +125 °C automotive temperature grade, making it suitable for harsh industrial and automotive environments. Its 3.3V supply operation minimizes power dissipation in battery-powered and point-of-load regulated systems. The architecture uses a differential line driver with slew-rate-limited outputs to reduce EMI while still delivering 20 Mbps throughput. Internal hysteresis on the receiver inputs combined with the failsafe circuit ensures clean logic transitions even with significant bus attenuation or noise. The device draws low quiescent current, allowing many transceivers to share a single 3.3V rail without thermal concerns. Typical applications include industrial fieldbus networks (Modbus, Profibus DP), building automation (BACnet, RS485 lighting control), automotive body and chassis networks, point-of-sale terminals, and long-cable RS422 point-to-point links. The wide common-mode range also supports harsh electrically noisy environments such as motor drives and factory automation. When designing with this part, place 100 nF decoupling capacitors as close as possible to the VCC pin and provide proper cable termination (typically 120 Ω) at both ends of the bus. The half-duplex topology requires that only one driver be enabled at a time; software UART flow control or hardware direction-control timing must enforce this to avoid contention.

LTC2852IMS#PBF - 3.3V 20Mbps RS485/RS422 Transceiver | ADI
The Analog Devices LTC2852IMS#PBF is a low-power, 3.3V full-duplex RS485/RS422 transceiver rated for 20 Mbps signaling and housed in a 10-pin MSOP package. It features a one-eighth unit-load receiver input (supporting up to 256 nodes per bus on C- and I-grade devices), integrated hot-swap capable driver outputs, and a failsafe receiver that guarantees a logic-high output under floating, shorted, or terminated bus conditions. An RS485/RS422 transceiver is a differential line driver/receiver IC that translates between a single-ended UART/logic interface and a twisted-pair differential bus, enabling robust, long-reach, noise-immune communication in industrial, building-automation, and instrumentation systems. The LTC2852 belongs to the broader RS-422/RS-485 interface IC category (sub-category of Interface ICs) within the broader semiconductor power management and signal-chain ecosystem. Its 3.3V supply aligns with modern low-voltage MCUs and FPGAs, eliminating the level shifters required by legacy 5V transceivers. Key features include 3.3V single-supply operation, 20 Mbps data rate, 1/8th unit load (256-node fan-out on C/I grade), integrated hot-swap/tolerant driver outputs that remain high-impedance across the full common-mode range when disabled, low current per package (500 µA typical supply current), and industry-standard RS485/RS422 pinout. The MSOP-10 footprint enables compact node designs typical of multi-drop industrial backbones. Internally, the LTC2852 uses a precision differential line driver with slew-rate-limited edges (for low EMI) and a window-comparator receiver topology that detects 200 mV differential signals as required by TIA/EIA-485. The one-eighth unit-load input impedance reduces bus loading by 8× compared to legacy 1-unit-load parts, allowing more nodes on the same bus without exceeding the 32-unit-load RS485 specification limit. Typical applications include industrial fieldbus networks (Modbus, Profibus DP at 20 Mbps), building automation (BACnet MS/TP, lighting control), point-of-sale peripherals, multi-drop motor controller links, and RS422 point-to-point communication between embedded controllers and sensors. Designers choose the LTC2852 when they need a 3.3V-only transceiver with a small package, robust hot-swap performance, and high node count. When designing with this device, place 100 nF supply bypass capacitors within 5 mm of the VCC pin, use a 100 Ω termination resistor at each bus end, and verify common-mode protection in electrically noisy environments. The #PBF suffix denotes a lead-free, RoHS-compliant finish. This page synthesizes distributor pricing, parametric alternates, and practical design notes that complement - and go beyond - the manufacturer datasheet's nominal spec table.
LTC2862AIS8-2 - ±60V RS485/RS422 Transceiver | Analog Devices
The Analog Devices LTC2862AIS8-2 is a low-power, half-duplex RS485/RS422 transceiver with ±60V fault protection, operating on 3V to 5.5V supplies and housed in an 8-pin SOIC package. It supports two speed grades selectable via part variant: 20Mbps (the -2 suffix denotes a high-speed version) or 250kbps, with 1/1 driver/receiver count. The interface pins withstand ±60V overvoltage faults during all modes of operation including power-down. An RS485/RS422 transceiver is a physical-layer device that converts between a single-ended UART/CMOS logic signal on the microcontroller side and a robust differential signal on the bus side, enabling reliable serial communication over twisted-pair cables at distances up to 1200 meters. RS485 is the de-facto standard for industrial multipoint buses (Modbus RTU, Profibus, DMX512) while RS422 is used for point-to-point high-speed links; the LTC2862 family supports both. Half-duplex means one differential pair is shared between transmit and receive, with direction controlled by a logic pin. Key features include ±60V fault tolerance on the bus pins, IEC 61000-4-2 Level 4 ESD protection (typically 8 kV contact, 15 kV air per the manufacturer's IEC ESD rating), current-limited drivers, thermal shutdown, and a fully balanced differential receiver threshold for low duty-cycle distortion. The 8-pin SOIC package is pin-compatible with legacy LT1785/LT1791 footprints and the original LTC2862 family, enabling direct board replacement. The LTC2862A uses a CMOS process with switched-capacitor charge pump to generate the ±60V fault-tolerant driver supply. The architecture delivers low quiescent current during idle while still maintaining high drive strength during bus arbitration, and the receiver exhibits 250 mV typical hysteresis with a 50 mV worst-case offset to meet TIA/EIA-485-A. Typical applications include industrial fieldbus networks (Modbus, Profibus), solar inverter monitoring, building automation (BACnet), motor control encoder links, and any 3V-5V MCU interface that must survive miswiring, ESD strikes, or transient overvoltage events on long cable runs. The wide 3V-5.5V supply range also supports battery-powered remote sensor nodes. When designing with this device, place 100 nF decoupling close to VCC and use twisted-pair cable with proper termination (120 Ω) at the bus ends. The -2 suffix denotes 20 Mbps high-speed grade; the -1 variant is 250 kbps low-EMI grade - select based on your data rate and EMI budget.
LTC2863IS8-1 - ±60V Fault-Protected RS485/RS422 Transceiver | ADI
The Analog Devices LTC2863IS8-1#PBF is a ±60V fault-protected, 3V to 5.5V supply, full-duplex RS485/RS422 transceiver housed in an 8-pin SOIC (IS8) package. Per the manufacturer datasheet, it integrates one driver and one receiver (1/1), supports data rates up to 20 Mbps, and tolerates ±60V on the bus pins without damage, a level that exceeds the typical RS485 common-mode range of -7V to +12V by a wide margin. A transceiver is a semiconductor device that bridges two distinct electrical interfaces, in this case translating between low-voltage CMOS logic on the controller side and the differential, bus-terminated signaling required by the RS485/RS422 standard. RS485/RS422 transceivers sit inside the broader interface-IC hierarchy: interface IC > line driver/receiver > differential transceiver > RS485/RS422 transceiver. The LTC2863 family is positioned for harsh industrial bus networks where hot-plug events, wiring faults, and surge exposure are routine. Key features include ±60V fault protection on driver outputs and receiver inputs, ±25V HBM ESD protection on the bus pins, 1/8 unit load (up to 256 nodes per bus), current-limited drivers with thermal shutdown, and a fully balanced differential receiver threshold that minimizes duty-cycle distortion. The -1 suffix denotes the full-duplex (no shared DE/RE control timing constraint) pinout variant in the 8-lead SOIC; the -2 variant differs in enable logic. Per the manufacturer datasheet, MP-grade (-55°C to 125°C) and DFN package options are also available in the LTC2863 family. Architecturally, the device combines a differential line driver with a wide-input-range differential receiver, both protected by on-chip TVS-style clamping structures. The 3V-5.5V VCC range allows direct connection to 3.3V or 5V microcontrollers without level shifters, simplifying BOM and reducing board area. Pin compatibility with the LT1785 and LT1791 families (per Analog Devices product page) means existing designs can be ruggedized against field faults with no layout rework. Typical applications include industrial fieldbus networks (Modbus, Profibus, BACnet), building automation, motor drive feedback links, smart-grid metering, and any long-cable RS485 link exposed to installation transients or mis-wiring. The ±60V tolerance protects against accidental AC mains contact on the bus. When laying out the LTC2863IS8-1, keep the bus traces short and matched, place the bus termination at the end nodes, and provide a solid ground plane; the IC's internal fault protection does not replace good EMC practice. Use a 100nF decoupling capacitor close to VCC and add a 10µF bulk capacitor if the supply is shared with switching regulators.
LTC2870IFE - RS232/RS485 Multiprotocol Transceiver | Analog Devices
The Analog Devices LTC2870IFE is a pin-configurable multiprotocol transceiver supporting RS232, RS485, and RS422 on shared I/O lines, operating from a single 3V to 5.5V supply in a 28-pin TSSOP-EP package. The device integrates switchable termination resistors, configurable as two single-ended RS232 transceivers or one differential RS485/RS422 transceiver, with 2/2 (driver/receiver) channel count. A multiprotocol transceiver is a mixed-standard interface IC that allows a single port to communicate over multiple physical-layer protocols (RS232 point-to-point, RS485/RS422 multi-drop differential). The LTC2870 belongs to the transceiver -> line driver/receiver -> interface IC -> integrated circuit hierarchy. This protocol flexibility reduces BOM count when a system must support both legacy RS232 equipment and modern differential RS485 industrial fieldbuses without two separate transceivers. Key features include ±15 kV ESD protection on the transceiver I/O pins (HBM), integrated switchable RS485 120 ohm termination, full-duplex and half-duplex RS485 modes, slew-rate-limited RS485 driver for low EMI, and a wide common-mode range exceeding the RS485 requirement. The exposed pad (TSSOP-EP) package improves thermal dissipation for high-load industrial environments. Logic inputs are 5V tolerant when operating from 3.3V supply, simplifying level shifting with MCUs and FPGAs. Technically, the LTC2870 uses charge-pump technology for RS232 ±5V drivers while running from a single low-voltage rail, and a precision differential line driver for RS485/RS422. Internal logic configures the protocol by setting mode pins; the shared bus pins are reorganized between single-ended and differential operation without external switching. The receiver features 25 mV typical hysteresis for noise immunity on long RS485 cables. Typical applications include industrial programmable logic controllers (PLCs) with mixed RS232/RS485 ports, point-of-sale (POS) terminals, building automation gateways, multi-protocol instrumentation, and HVAC controllers. The integrated termination eliminates external resistor networks and improves field reliability. When designing with this part, place 0.1uF decoupling capacitors close to VCC pins and connect the exposed pad to a low-impedance ground plane for thermal and EMI performance. Verify mode-pin logic levels match the selected protocol during firmware development to avoid bus contention.
LTC2870IFE#PBF - RS232/RS485 Multiprotocol Transceiver | Analog Devices
Analog Devices LTC2870IFE#PBF is a robust pin-configurable multiprotocol transceiver supporting RS232, RS485, and RS422 protocols from a single 3V to 5.5V supply, housed in a 28-pin TSSOP-EP (FE) package. The LTC2870 integrates one RS485 differential transceiver and two RS232 single-ended transceivers on shared I/O lines, with automatic integrated termination resistor selection. According to the Analog Devices LTC2870/LTC2871 datasheet, the device supports data rates up to 20 Mbps for RS485 and 500 kbps for RS232, with ±25 kV ESD (HBM) protection on the bus pins. An RS232/RS485 multiprotocol transceiver is an interface IC that bridges a UART, microcontroller, or processor to a physical serial bus. The RS232 standard uses single-ended signaling (logic-high and logic-low on separate lines with ±5V to ±15V swings) and is common in point-to-point links to legacy PCs and industrial controllers. The RS485 standard uses differential signaling (A-B differential voltage) and enables multipoint half-duplex or full-duplex networks up to 1200 m with up to 32 unit loads. Multiprotocol transceivers combine both physical layers on shared pins so a single PCB footprint can serve multiple end-equipment variants, reducing BOM and qualification cost. Key features of the LTC2870 include shared I/O lines between RS232 and RS485 modes, automatic or logic-controlled 120 ohm RS485 termination, ±25 kV ESD HBM on the bus I/O pins, hot-swap glitch protection, and a low-current shutdown mode. The integrated loopback mode allows self-test of the RS232 path without external cabling. The single 3V to 5.5V supply eliminates the negative charge pump traditionally required for RS232, simplifying power tree design. Typical applications include industrial multipoint fieldbus nodes, point-of-sale terminals, RS232-to-RS485 protocol converters, and any system that must communicate to both legacy RS232 equipment and modern RS485 networks. The TSSOP-EP package provides low thermal resistance for reliable operation at the extended industrial temperature range. When designing with the LTC2870, the shared I/O pins require careful PCB routing to avoid coupling between RS232 single-ended and RS485 differential traces; the exposed pad must be soldered to a thermal copper pour for specified thermal performance.
LTC2875HS8#PBF - 60V Fault-Protected CAN Transceiver | ADI
The Analog Devices LTC2875HS8#PBF is a robust, high-speed, low-power CAN (Controller Area Network) transceiver that operates from a 3.3V or 5V supply and features ±60V overvoltage fault protection on the bus pins during all modes of operation, including power-down. The device supports data rates up to 4 Mbps (CAN FD capable) and is housed in an 8-pin SOIC (HS8) package. Per the Analog Devices LTC2875 datasheet, the part is intended for 3.3V or 5V CAN networks requiring tolerance to large common-mode transients such as load-dump events in 12V/24V automotive or industrial systems. What is a CAN transceiver? A CAN transceiver is an interface IC that sits between a CAN protocol controller (typically a microcontroller) and the physical differential two-wire CAN bus (CANH/CANL). It converts the controller's CMOS/TTL TX/RX logic into the differential dominant/recessive signaling required by ISO 11898-2/ISO 11898-5, providing ESD and overvoltage robustness, common-mode rejection, and the bus-level protection that the controller itself cannot supply. The LTC2875 belongs to the interface IC -> transceiver IC -> CAN bus transceiver category inside the broader CAN bus driver / CAN FD transceiver family. Key features include ±60V bus fault protection, ±25kV ESD (HBM) on the CANH/CANL pins, ISO 11898-2 and ISO 11898-5 conformance, low current shutdown mode, SPLIT pin for recessive stabilization, and a wide supply range of 3V to 5.5V. The driver output stage is internally slew-rate limited and guarantees VSYM (driver symmetry) so the part can be used in CAN FD frames up to 4 Mbps. The LTC2875 combines an NPN/PNP bipolar bus driver with a precision differential receiver and a charge-pump-assisted protection rail that clamps bus voltages above and below the supply rails. The integrated ±60V fault path is active even in shutdown and power-off states, an important differentiator versus conventional CAN transceivers that lose protection when VCC collapses. Typical applications include automotive body and chassis ECUs, industrial CAN nodes with long cabling exposed to 24V/48V supply transients, building automation and HVAC CAN networks, and any 3.3V or 5V MCU-based system that must survive miswiring or load-dump events on the bus. When designing with this part, place 100nF supply decoupling as close as possible to VCC and add TVS diodes (or use the part's integrated ±60V clamp) to guarantee fault survival. The SPLIT pin typically requires a 10kΩ/1nF RC network to ground for proper recessive-bias stabilization per the datasheet typical application circuit. This page synthesizes distributor pricing, drop-in 8-SO alternatives, and practical fault-protection design notes that are not collected in any single manufacturer datasheet, helping engineers select, source, and lay out the LTC2875HS8#PBF with confidence.

The device is sampling as of January 2025 and is offered in a mainstream BGA package suitable for high-bandwidth AI and cloud-computing platforms. A retimer is a signal-conditioning device placed in the middle of a high-speed serial link to re-clock and equalize degraded signals, restoring signal integrity across long PCB traces, cables, or connector paths. The M88RT61632 sits in the PCI Express / Compute Express Link physical layer stack — PCIe 6.x uses PAM4 modulation at 64 GT/s, doubling the bandwidth of PCIe 5.0 NRZ 32 GT/s. Retimers are increasingly required in AI server fabrics where GPU-to-GPU and GPU-to-CXL-memory links traverse long channels inside the chassis. Key features include 16 lanes of PCIe 6.x/CXL 3.x with per-lane PAM4 64 GT/s operation, link budget above 40 dB, low-latency retransmission, and compatibility with mainstream industry packaging. Montage's proprietary SerDes IP supports the FLIT-mode framing and FEC structures defined in the PCIe 6.x specification, ensuring full compliance with the PCI-SIG and CXL-3.x standards. Architecturally, the chip integrates analog front-ends with CTLE, DFE, and adaptation engines, plus protocol-aware PCS layers for PCIe and CXL.

Provide low-impedance supply rails and isolated analog/digital grounds to maintain the 64 GT/s link budget. Confirm firmware is loaded via the host BMC or system management interface during bring-up. This page synthesizes manufacturer specifications, distributor availability, and PCB design considerations for engineers evaluating the M88RT61632 in next-generation AI server and CXL memory platforms — information not consolidated in the manufacturer brief alone.
MALD-37445 - Quad 25G/26G CDR VCSEL Driver | MACOM
MACOM MALD-37445 is a quad-channel 24.33 Gbps or 25.78 Gbps VCSEL driver with integrated clock-and-data recovery and input equalization, supplied as a 3 mm × 2 mm die. Its four transmit channels consolidate input equalization, CDR retiming, and laser-drive functions into one optical-transmit solution. Outputs are spaced at 250 µm centers to align with standard optical interfaces. The reference-free CDR supports 24.33 Gbps and 25.78 Gbps operation and can be bypassed for legacy or non-standard data rates. A clock-and-data recovery IC is a high-speed signal-conditioning device that extracts timing information from a serial data stream and reconstructs a clean data output. A VCSEL driver is a semiconductor interface that converts high-speed electrical data into modulation current for a vertical-cavity surface-emitting laser. Together, these functions form part of the optical communication hierarchy: optical transceiver → transmit signal chain → clock and data recovery → VCSEL driver → semiconductor. The primary verified features of MALD-37445 are four integrated CDR/VCSEL-driver channels, two supported retiming rates of 24.33 Gbps and 25.78 Gbps, an input equalizer, reference-free CDR operation, CDR bypass capability, and 250 µm output spacing. This combination is intended to reduce transmit-path component count while supporting both standardized and legacy interfaces. The equalizer addresses channel-loss impairments before data reaches the CDR, while retiming improves signal integrity by removing accumulated timing variation. Architecturally, the device is optimized as a complete one-chip transmit solution for optical modules. Each channel combines receive-side input conditioning with transmit-side laser drive, allowing an optical subsystem to process incoming high-speed data for re-timing and forwarding. The selectable CDR-bypass path is important when interoperability depends on legacy or non-standard data rates that the internal retiming loop should not process. Typical uses include 25G and 26G optical-module transmit sections, quad-lane optical links, high-speed backplane or data-communication equipment, and systems requiring coordinated equalization, retiming, and VCSEL-drive functions. The output pitch directly supports compact optical-interface assembly, although the die format requires assembly-level design rather than conventional leaded or packaged-component replacement. Designers must treat MALD-37445 as a bare-die RF and mixed-signal component. Its 3 mm × 2 mm form does not establish a pin-compatible drop-in footprint by itself. Board assembly must follow MACOM's die pad definitions, assembly process, thermal path, and high-speed layout guidance. Differential routing, impedance control, return paths, and laser-drive current settings must be validated in the complete channel rather than inferred only from aggregate data rate. This page consolidates the verified manufacturer information, source links, packaging facts, application context, and engineering cautions. It distinguishes a complete optical transmit IC from merely similar high-speed drivers and avoids inventing electrical limits, prices, pin assignments, or replacement parts that the supplied evidence does not establish.
MAP1602 - Gen4 x4 4-Channel NVMe Controller | Maxio
The Maxio MAP1602 is a DRAMless NVMe solid-state-drive controller with a PCI Express Gen4 x4 host interface and a four-channel NAND interface supporting up to four CE devices per channel. The supplied product information identifies Smart Cache architecture, multi-core Fusion technology, and hardware/firmware co-design as methods used to improve resource utilization, read/write performance, and power efficiency. It is intended for designers developing PCIe Gen4 M.2 solid-state drives rather than for a conventional discrete analog or logic circuit. An SSD controller is a semiconductor system that coordinates a host interface, NAND media, firmware, cache management, error handling, and data-transfer paths. In the storage hierarchy, the MAP1602 is a storage controller, then an NVMe controller, then a PCIe interface controller, and finally a semiconductor used in solid-state storage. Its DRAMless architecture means external DRAM support is not identified in the supplied MAP1602 description; firmware and on-controller resources therefore carry greater responsibility for mapping and cache behavior. The verified interface data supports PCIe Gen4 x4 connectivity and four NAND channels, each supporting up to four CE devices per channel. The related controller PDF also associates MAP1202-I and MAP1602-I families with DRAMless PCIe/NVMe designs, but the supplied snippets do not establish the exact package, pinout, operating voltage, NAND timing, ECC capability, endurance, power figures, or lifecycle status for MAP1602. Those parameters must be confirmed against the original manufacturer documentation before schematic release or production sourcing. Typical design targets include M.2 NVMe SSDs, client notebooks, compact desktops, and other systems with a PCIe Gen4 x4 storage slot. The referenced SSD listing reports densities of 1TB and 2TB, sequential reads up to 7000MB/s, writes up to 6000MB/s, and a 3.3V ±5% supply condition for a module built around this controller; these are module-level claims, not guaranteed MAP1602 IC ratings. PCB design should preserve the high-speed PCIe and NAND signal-integrity requirements, provide correct power sequencing, and follow the manufacturer’s reference layout and firmware requirements. Because the available evidence does not provide a complete pinout or electrical table, engineers should not infer package details from unrelated MAP1602 listings. The public datasheet URL supplied here is a retrieved PDF reference, while its manufacturer and revision metadata remain to be confirmed. This page consolidates the verified interface capabilities, module-level SSD claims, architecture descriptions, and engineering limitations for MAP1602. It also distinguishes useful design context from unverified controller-level specifications so procurement and hardware teams can request the correct manufacturer package data before committing a design.
MAX13085EESA+ - 500kbps Fail-Safe RS-485/RS-422 | Analog Devices
The Analog Devices MAX13085EESA+ is a 5.0 V RS-485/RS-422 transceiver with one driver, one receiver, 500 kbps data rate, and ±15 kV ESD protection in an 8-pin SOIC package. It supports half-duplex communications and includes fail-safe receiver circuitry plus hot-swap capability. The verified material also reports a 1/8-unit-load receiver input impedance and up to 256 transceivers on the bus. Its low 1.2 mA unloaded or driver-disabled supply current suits power-conscious field-bus equipment. An RS-485/RS-422 transceiver is an interface IC that converts logic-level UART or controller signals into balanced differential bus signals, then converts received differential signals back into CMOS-compatible logic. RS-485 supports multipoint, half-duplex buses, while RS-422 commonly emphasizes point-to-point or driver-receiver links. The MAX13085E family belongs to the transceiver hierarchy: interface transceiver, wired communication interface, and semiconductor. The MAX13085E provides one driver and one receiver, 500 kbps operation, ±15 kV ESD protection, and fail-safe behavior that forces a logic-high receiver output when inputs are open, shorted, or all bus transmitters are disabled. Its hot-swap capability helps maintain predictable operation during connector mating. The 1/8-unit receiver loading lowers input impedance so as many as 256 compatible transceivers can share one bus. Its half-duplex architecture requires control of driver enable and receiver enable according to the selected bus topology. Supply filtering, protected cable routing, and correct termination are essential because a compliant transceiver alone does not guarantee an immune field connection. The stated 5 V operating range also requires systems to regulate the device from compatible rail voltages. Typical uses include industrial sensor buses, building automation, factory equipment, telecom racks, and remote monitoring links. It is particularly useful when a compact bus node needs one bidirectional half-duplex channel, robust electrostatic protection, and deterministic behavior during disabled-driver or hot-plug conditions. Designers should confirm the manufacturer pinout and enable polarity before routing the PCB, and should not infer RS-485 network performance from the 500 kbps device rate alone. Cabling, topology, termination, grounding, and transceiver matching determine practical range and reliability. This page combines verified manufacturer data, distributor availability information, and application-oriented engineering guidance. It also separates documented drop-in alternatives from unverified substitutions, helping engineers compare procurement and design options without treating merely similar interface ICs as pin-compatible replacements.
MAX13487EESA+ 500kbps RS-485/RS-422 Transceiver
The Analog Devices MAX13487EESA+ is a 5 V, half-duplex, 500 kbps RS-485/RS-422-compatible interface IC with one driver, one receiver, automatic direction control, and ±15 kV ESD protection in an 8-SOIC package. Designed for industrial data links, it combines differential bus communication with automatic transmitter-receiver switching, reducing the need for a separate isolated direction-control channel. An RS-485/RS-422 transceiver is an interface IC that converts between single-ended logic signals used by a controller or MCU and differential signals carried across a noisy, long-distance bus. It belongs to the communications-interface hierarchy: interface IC → differential transceiver → RS-485/RS-422 interface. One transceiver supports bidirectional half-duplex communication, so the same pair of bus conductors carries traffic in either direction, but only one side transmits at a time. The MAX13487EESA+ provides 500 kbps operation, a +5 V supply, automatic direction control, hot-swap capability, and ±15 kV ESD protection according to the manufacturer datasheet. AutoDirection control is particularly useful when the system has no convenient GPIO for asserting driver enable. Hot-swap capability helps prevent false bus transitions during startup and live insertion, while ESD protection improves robustness against electrostatic discharge encountered in industrial environments. The MAX13487EESA+ is suited to RS-485-compatible multidrop networks, RS-422-compatible point-to-point links, industrial control systems, instrumentation, building automation, and communications equipment where a compact 500 kbps half-duplex transceiver is required. The device is available in an 8-SOIC package, making it appropriate for conventional PCB assembly and replacement workflows. When designing around the MAX13487EESA+, verify the complete datasheet pinout, termination requirements, bus topology, grounding, and supply decoupling before production release. The automatic direction-control architecture should be reviewed for compatibility with the system’s bus timing and fault-recovery expectations. This page combines verified manufacturer and distributor information with package, application, and replacement-oriented engineering guidance.
