SN65HVD53D - High-Output Full-Duplex RS-485 Transceiver | Texas Instruments

The Texas Instruments SN65HVD53D is a high-output, full-duplex RS-485 and RS-422 transceiver with driver and receiver enable pins, packaged in a 14-pin SOIC (D). It combines one differential driver and one differential receiver with independent active-high driver enable (DE) and active-low receiver enable (RE) control, and it offers a 1/8 unit-load receiver option supporting up to 256 nodes on a single bus. A transceiver is the physical-layer interface that converts between a logic-level digital signal and a balanced differential line pair. An RS-485 transceiver belongs to the differential line-driver / receiver family, which sits under interface ICs, communication ICs, and ultimately semiconductor ICs. Differential signaling carries the same data on two wires of opposite polarity, so common-mode noise induced along the cable is rejected by the receiver, making RS-485 the dominant industrial bus for factory automation, instrumentation, and building control. Key differentiators of this device include bus-pin ESD protection exceeding 15 kV HBM, selectable driver output transition times supporting signaling rates of 1 Mbps, 5 Mbps and 25 Mbps, a low-current standby mode drawing about 1 uA when both the driver and receiver are disabled, and glitch-free receiver outputs. The 14-pin SOIC body measures 3.90 mm wide and is rated for -40 C to +85 C operation, covering industrial temperature ranges without a hermetic or extended package. Internally, the SN65HVD53D uses a differential driver stage with selectable slew rate to control edge energy on the bus and limit EMI, while the receiver front end presents a low unit load so many nodes can share one cable run. Enable pins give the system designer direct control over bus direction and shutdown, which is valuable in multi-drop networks where multiple transceivers must not all drive simultaneously. Typical deployments include industrial RS-485 field buses, PLC and remote I/O links, building HVAC and access-control networks, utility and metering equipment, and instrumentation links where a full-duplex point-to-point topology with separate driver and receiver enables is required. When laying out the board, keep the differential pair tightly coupled with a continuous ground reference beneath it, place the bypass capacitors at the supply pins, and treat the enable pins as digital control signals that must be sequenced so that only one node drives the bus at a time. This page consolidates device specifications, enable-logic differences against sibling family members, drop-in alternatives, and practical layout guidance into a single engineering reference that goes beyond a basic catalogue entry.

SN65HVD54D

SN65HVD54D - 5 Mbps Full-Duplex RS-485 | Texas Instruments

The Texas Instruments SN65HVD54D is a high-output, full-duplex RS-485 driver and receiver with separate driver and receiver enables, operating from a single 5 V supply in a 14-pin SOIC (D) package. It supports signaling rates up to 5 Mbps, provides a 1/8-unit-load option for as many as 256 nodes on a bus, and includes bus-pin ESD protection exceeding 15 kV HBM. The device also offers a low-current standby mode with 1 µA typical standby current and selectable driver transition times optimized for 1 Mbps, 5 Mbps, and 25 Mbps signaling environments. An RS-485 transceiver is an interface integrated circuit that combines a differential line driver and differential receiver for balanced digital communications. It belongs to the RS-422/RS-485 transceiver hierarchy within interface ICs, where the driver translates logic-level signals into differential bus voltage and the receiver converts differential bus voltage back into a logic-level signal. Full-duplex operation provides separate paths for transmission and reception, making the SN65HVD54D suitable for systems that cannot share the same bus conductors in both directions. The SN65HVD54D provides one driver and one receiver, with independent enables that allow the system to place either side into a low-power state. Its high-output architecture is intended for demanding balanced-line links, while the selectable driver edge rates let engineers optimize signaling behavior for 1 Mbps, 5 Mbps, or faster communication links. The 1/8-unit-load receiver option can support up to 256 nodes, reducing the loading burden in large multi-node industrial systems. Bus-pin ESD protection exceeding 15 kV HBM adds an important ruggedness margin where cables and external connectors are exposed to electrostatic discharge. The device operates across the -40 °C to +85 °C temperature range in the SN65HVD54D ordering option. Its separate full-duplex driver and receiver structure is particularly useful when the transmitting and receiving nodes must remain active simultaneously. Typical uses include industrial factory automation, building-control networks, industrial instrumentation, motor-control systems, process monitoring, and other full-duplex RS-485 links. The 5 Mbps capability supports factory-floor communication, while the standby function can reduce consumption when a node is not communicating. Component placement and termination remain important because the transceiver does not eliminate the need for a balanced cable, appropriate bus topology, and correctly engineered termination. Designers should verify enable polarity in the host logic, place the device close to the bus connector, and provide protection appropriate to the installation environment. The internal high-impedance state supports controlled bus participation, but software and fault-management circuitry must still prevent multiple transmitters from driving the same bus at the same time. This page consolidates verified manufacturer and distributor information, package details, lifecycle attributes, replacement guidance, and application-oriented engineering context. It also distinguishes documented drop-in family options from alternatives that may require different packages or interface behavior, helping engineers shorten component-selection and PCB-validation work.

SN65HVD55D

SN65HVD55D - 1Mbps Full-Duplex RS-485 | Texas Instruments

The Texas Instruments SN65HVD55D is a high-output, full-duplex RS-485 driver and receiver with enables, supporting data rates up to 1 Mbps and operation from -40°C to +85°C in a 14-pin SOIC package. It provides a 1/8-unit-load option for networks containing as many as 256 nodes, 50 mV receiver hysteresis for improved noise immunity, and bus-pin ESD protection exceeding 15 kV HBM. An RS-485 transceiver is a bidirectional communications interface that combines a differential line driver, a differential receiver, and associated enable controls. It belongs to the interface-IC hierarchy and enables robust communication over long, noisy cables by representing digital data as a differential voltage across a balanced pair of conductors. The SN65HVD55D uses separate driver and receiver paths, allowing full-duplex operation on a four-wire bus. Key features include a maximum data rate of 1 Mbps, 1/8-unit-load operation, and optional driver transition times intended for signaling rates of 1 Mbps, 5 Mbps, and 25 Mbps. The low-current standby mode consumes 1 µA, making the enables useful for power-conscious systems. Bus-pin ESD protection exceeding 15 kV HBM helps improve robustness where cables connect the transceiver to external equipment. The high-output architecture increases the amount of signal energy available on the bus, while the receiver's 50 mV hysteresis rejects noise within the transition region between differential output states. The device is suitable for RS-422 and RS-485 equipment where point-to-point or multipoint differential signaling is required. Its independent enable controls permit the driver and receiver to be switched according to the operating state of the connected system. Typical applications include industrial automation equipment, factory-floor controllers, building-control systems, data-acquisition equipment, communications modules, and external bus interfaces. In a full-duplex installation, the driver connects to one differential pair and the receiver connects to another pair, allowing simultaneous transmission and reception without sharing the same bus conductors. Designers should account for cable length, topology, termination, grounding, and the slew-rate option when selecting the device. The bus must remain within the transceiver's specified electrical limits, and unused inputs should be handled according to the manufacturer guidance. Enable sequencing should also prevent simultaneous bus contention where multiple nodes share a conductor pair. This product page combines the verified manufacturer description, distributor availability, package information, RS-485 operating characteristics, and documented family differences. It also provides application guidance and a structured comparison for engineers evaluating drop-in interface choices without adding unverified electrical claims.

SN65HVD61D

SN65HVD61D - Single-Channel ControlNet Transceiver | Texas Instruments

Texas Instruments SN65HVD61D is a single-channel ControlNet physical-layer transceiver with one driver and one receiver, supplied in a 14-pin SOIC package. Designed for single-node operation and distributed stand-alone applications, it provides the circuitry required by ControlNet coaxial-based physical layers. Its pull-or-pull transmitter sinks current from a center-tapped transformer, supporting galvanic isolation between the transceiver circuitry and the external network interface. The combination of one integrated transceiver channel, transformer-compatible drive topology, and a compact 14-SOIC package makes the device applicable to industrial automation, controller, sensor, and factory-control networks. A ControlNet transceiver is a specialized interface IC that converts digital logic signals into a balanced physical-layer network connection and converts received network signals back into logic-level data. Within the product hierarchy, it belongs to the interface transceiver class, with ControlNet operation representing its defining protocol and physical-layer function. Its isolation-oriented transmitter arrangement is particularly useful where system designers require a transformer-based link between the transceiver and a coaxial cable network. The SN65HVD61D integrates one driver and one receiver into a single channel. The manufacturer describes the transmitter as a pull-or-pull arrangement that sinks current from a center-tapped transformer rather than driving the cable directly. This architecture allows the external transformer to establish the physical signal coupling and galvanic isolation. The 14-SOIC package supports conventional surface-mount assembly while providing a practical pin count for a complete single-channel interface. The primary system benefit is functional consolidation: one device contains both sides of the ControlNet physical-layer connection. This can reduce the number of separate interface components required for a single-node or stand-alone node. The galvanic-isolation capability provided by the center-tapped transformer arrangement is also important in industrial environments where isolation between the electronic circuitry and external cabling is a system requirement. Actual isolation voltage, data rate, supply range, and timing limits must be confirmed in the manufacturer datasheet before final qualification. Typical use cases include ControlNet-compatible programmable logic controllers, industrial automation controllers, remote I/O nodes, factory sensor interfaces, motor-control supervisory nodes, and distributed process-monitoring equipment. In each case, the SN65HVD61D handles the local logical transceiver function while a suitable center-tapped transformer connects the device to the ControlNet physical layer. The primary design consideration is transformer and network compatibility. The external center-tapped transformer must match the device's electrical and timing requirements, and its wiring must preserve the intended isolation boundary. PCB signal integrity, return paths, bypass-capacitor placement, and connector or cable characteristics also require careful implementation because the transceiver communicates through a coupled physical layer rather than a direct point-to-point logic interface. This page consolidates the verified manufacturer description, distributor identification, package information, sourcing links, and practical engineering guidance. It also distinguishes the SN65HVD61D from family ordering variants and identifies where additional electrical, timing, compliance, or lifecycle data must be obtained from the authoritative manufacturer documentation.

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.

The device can also support point-to-point RS-422-style connections when the system requires independent transmit and receive paths. Designers should check the pin assignment and termination requirements in the manufacturer datasheet before layout. A 120-ohm termination resistor is commonly used at each end of a standard RS-485 bus, while bias resistors should be placed only where required. Keep the differential pair routed together, minimize stubs, and provide a stable return path to reduce common-mode noise. This product page combines the manufacturer's electrical specifications with practical interface guidance, application context, comparison information, and verified sourcing references. It is intended to help engineers identify whether the SN65HVD71D fits a 3.3 V full-duplex RS-485 design before beginning PCB implementation.

An RS-485 transceiver is a physical-layer interface IC that converts low-voltage digital logic signals into differential bus signals and reconstructs logic-level data from a differential bus. It belongs to the transceiver hierarchy within interface ICs and enables robust, point-to-point or multidrop communication over longer distances than single-ended logic interfaces. Full duplex means the driver and receiver can operate simultaneously on separate differential pairs. The SN65HVD73D's principal features include a 20 Mbps data rate, 70 mV receiver hysteresis, separate active-high driver enable and active-low receiver enable controls, and ±12 kV IEC-rated ESD protection. Its 3 V to 3.6 V operating range is appropriate for 3.3 V systems. The broad -40°C to +125°C temperature range supports industrial and extended-temperature equipment when the complete system qualification permits it. The integrated driver and receiver provide one RS-485/RS-422 communication channel in full-duplex configuration. Separate enables allow the transmitter and receiver to be disabled independently, and the manufacturer product page states that standby current can be reduced below 5 µA when both functions are disabled. A common ground reference and carefully terminated differential wiring remain necessary for reliable operation. Typical applications include industrial control networks, factory automation equipment, data acquisition systems, building-automation controllers, and communications between a host controller and a peripheral transceiver. The 20 Mbps capability supports high-speed point-to-point links, while the ±12 kV IEC ESD rating helps protect external bus connectors in electrically noisy environments. Designers should follow the manufacturer datasheet for transceiver pinout, termination, fail-safe biasing, and differential routing. Keep the RS-485 differential pair routed as a controlled-impedance pair, minimize stub lengths, place termination only where required by the bus topology, and verify grounding and surge-protection requirements for the installed environment. This product summary consolidates verified manufacturer and distributor information, supply parameters, design guidance, and replacement constraints into one engineering-focused reference. It also clearly distinguishes verified specifications from electrical values that require confirmation from the complete datasheet before schematic release.

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.

It combines one differential driver and one differential receiver, providing separate data paths for simultaneous bidirectional communication over an RS-485 bus. The device supports a 3.0 V to 3.6 V supply range and operates from -40°C to 125°C. A transceiver interface IC converts between digital logic signals and balanced differential bus signals. The SN65HVD74 belongs to the RS-485 transceiver category within interface ICs, interface semiconductors, and broader communication semiconductors. Its differential signaling improves noise immunity by comparing the voltage between two bus conductors rather than referencing one conductor to ground, making it suitable for industrial, building-automation, and communications equipment operating over longer cable runs. The SN65HVD74D combines a 20 Mbps maximum data rate with more than 30 kV HBM ESD protection and more than 12 kV IEC61000-4-2 contact-discharge protection. Receiver hysteresis is 70 mV, helping reject conducted differential noise and prevent unwanted output transitions. Separate driver and receiver input and output pins support full-duplex bus arrangements without sharing a single half-duplex direction-control path. The transceiver operates from a single 3.3 V power supply and supports both RS-485 and RS-422 interface applications. Its surface-mount SOIC package permits automated assembly, while the stated -40°C to 125°C operating range supports industrial equipment, data-acquisition systems, factory controls, and industrial communication equipment. Each driver and receiver has separate input and output pins, allowing transmit and receive paths to operate simultaneously. Typical applications include full-duplex RS-485 industrial networks, high-speed instrumentation links, factory automation equipment, building-control systems, and industrial data acquisition. In a typical circuit, the microcontroller-facing pins connect to digital logic, while the differential A, B, Y, and Z pins connect to the balanced bus through suitable termination and protection components. The 70 mV receiver hysteresis helps maintain reliable decisions in electrically noisy environments. When designing the interface, maintain compatible logic levels, observe recommended bus biasing and termination, and verify that the selected cable length and topology remain valid for 20 Mbps operation. Protection-device capacitance should be included when calculating edge rate and channel performance. The 3.3 V supply must remain within the specified 3.0 V to 3.6 V range, and system designers should check all logic thresholds against their controlling device. This page combines the manufacturer's key electrical and environmental ratings with practical interface-design guidance, packaging information, and a focused drop-in replacement assessment. It highlights where the SN65HVD74D fits within a 3.3 V full-duplex RS-485 design and the checks that matter when evaluating bus speed, ESD robustness, receiver noise immunity, and PCB implementation.

The wide -40°C to 125°C temperature range also makes the device suitable for industrial environments where commercial-temperature interface ICs may be inadequate. Exact ESD ratings, receiver thresholds, and electrical limits must be confirmed in the manufacturer datasheet. Each device combines a differential driver and differential receiver operating from one 3.3 V power supply. The bus pins are designed for robust ESD-event handling, including Human Body Model and IEC Contact Discharge protection. The manufacturer datasheet also identifies 250 kbps, 20 Mbps, and 50 Mbps signaling-rate options across the SN65HVD7x family, with 20 Mbps specifically associated with the SN65HVD75. Typical uses include industrial automation controllers, factory data buses, industrial instrumentation, building automation, and communications equipment operating on RS-485 networks. Its 20 Mbps capability supports high-speed half-duplex links, while 5 V-tolerant logic inputs ease interfacing with both 3.3 V and 5 V controllers. The half-duplex arrangement also requires careful direction-control design because the driver and receiver share the same bus pair. When designing the circuit, place a 100 nF ceramic bypass capacitor close to the supply pins and use a 3.3 V source capable of supporting the transceiver's operating current. The manufacturer recommends the TPS76333 for a suitable 3.3 V supply and the SN6501 for isolated power-supply designs. Bus routing should minimize stubs and maintain controlled differential impedance. This page combines verified manufacturer and distributor information, transparent pricing-status notes, same-family replacement analysis, and practical RS-485 design guidance. It also distinguishes verified electrical facts from parameters that still require confirmation against the complete SN65HVD7x manufacturer datasheet.

SN65HVD76D

SN65HVD76D - 50Mbps Full-Duplex RS-485 | Texas Instruments

Texas Instruments SN65HVD76D is a 3.3 V full-duplex RS-485 transceiver with a 50 Mbps data rate, separate driver and receiver enables, and 12 kV IEC contact-discharge ESD protection. It is packaged as a 14-pin SOIC for surface-mount industrial and instrumentation systems. An RS-485 transceiver combines a differential line driver and differential receiver to communicate reliably over noisy, long-distance industrial buses. The SN65HVD76 family supports both RS-485 and RS-422 applications, while its full-duplex architecture provides simultaneous transmit and receive paths through separate differential pins. It operates from a single 3.3 V power rail, simplifying integration with 3.3 V controllers, sensors, gateways, and test equipment. The principal features include a 50 Mbps maximum data rate, 1/8 unit-load receiver operation for up to 256 nodes, a 70 mV receiver hysteresis, and separate enable controls. According to the Texas Instruments product page, the driver enable is active high and the receiver enable is active low. Disabling both functions can reduce standby current to less than 5 uA, making the device useful in low-power distributed systems. Bus protection includes greater than 30 kV human-body-model protection and greater than 12 kV IEC 61000-4-2 contact-discharge protection, together with greater than 4 kV IEC 61000-4-4 fast-transient burst protection. These ratings help protect the transceiver in electrically noisy environments, although they do not eliminate the need for correct common-mode grounding, cable selection, and termination practices. Typical applications include industrial RS-485 links, factory automation equipment, building controls, instrumentation, and high-speed data acquisition. Full-duplex operation is particularly appropriate when continuous receiving is required while the controller also transmits status, configuration, or diagnostic data. The 14-pin SOIC format also supports conventional surface-mount assembly and thermal design. For a new layout, place the transceiver and its protection or bypass components near the bus connector, maintain a continuous ground reference with the cable, and apply termination only where required by the network topology. Verify that the selected logic controller can tolerate the receiver output levels and that the bus does not exceed the device's electrical limits. This page combines the exact device specifications, practical RS-485 design guidance, application fit, and package-level comparison information. It also distinguishes true board-level drop-in options from related family members whose enable behavior or transceiver configuration differs, helping engineers avoid selecting a substitute that requires schematic or layout changes.

SN65HVD77D

SN65HVD77D - 3.3V 50Mbps Full-Duplex RS-485 | Texas Instruments

Texas Instruments SN65HVD77D is a 3.3 V full-duplex RS-485 transceiver with a 50 Mbps data rate, ±12 kV IEC ESD protection, and an 8-pin SOIC package. It combines one differential driver and one differential receiver in a single package, allowing transmit and receive paths to operate simultaneously. The device operates from 3.0 V to 3.6 V and is specified across -40°C to 125°C. An RS-485 transceiver is an interface IC that converts logic-level signals into differential bus signals and converts received differential signals back into logic levels. RS-485 belongs to the differential data-interface hierarchy, where the voltage between the A and Y conductors carries the signal while common-mode noise is rejected. The SN65HVD77D is designed for robust, point-to-point, multidrop, and full-duplex industrial communication links. The primary feature of the SN65HVD77D is its 50 Mbps signaling capability, making it suitable for high-speed data acquisition, factory automation, industrial control, and communications equipment. Its ±12 kV IEC-rated ESD protection improves system resilience when cables connect the transceiver to external equipment. Operating from a 3.3 V rail also simplifies integration with 3.3 V controllers, FPGAs, DSPs, and other digital logic. Each device contains separate driver and receiver inputs and outputs, eliminating the shared bus direction controls commonly found on half-duplex transceivers. Full-duplex operation allows data to be transmitted and received at the same time. The transmitter drives a differential pair, while the receiver provides a complementary logic-level output. Because there are no external enable controls, the device is intended for continuous enabled operation rather than controlled low-power bus shutdown. Typical implementations connect the logic-side data pins to a communications controller, connect the A and Y pins to a protected twisted-pair bus, and place the receiver output in the controller's receive path. Full-duplex systems use separate differential pairs for transmission and reception. The SOIC-8 package supports conventional surface-mount assembly and is suitable for industrial control boards, test equipment, motor-control systems, and embedded communications modules. The principal design consideration is signal integrity. High-speed differential routing requires controlled impedance, a continuous return path, minimized stubs, and proper termination at the bus endpoints. External protection may still be required for severe industrial transients because the integrated ESD rating addresses electrostatic discharge rather than every surge or lightning event. This product page combines the manufacturer's principal electrical and environmental specifications with same-package transceiver options, application guidance, and practical PCB-layout considerations. These engineering details help simplify device selection, footprint verification, and robust RS-485 implementation.

SN65HVD96D

SN65HVD96D - 5 Mbps SymPol Transceiver | Texas Instruments

The Texas Instruments SN65HVD96D is a half-duplex, 1/1 SymPol transceiver operating from a single 5 V supply in an 8-pin SOIC package. It supports signaling up to 5 Mbps, communicates reliably on normal or reversed-wire bus lines, and uses a symmetric-polarity receiver with 100 mV hysteresis. These characteristics make it suitable for industrial point-to-point, multi-drop, and multi-point communication networks. A SymPol transceiver is a physically robust bus interface integrated circuit that combines a differential driver and differential receiver into one package. It belongs to the interface IC hierarchy, alongside RS-485 transceivers, but uses symmetric polarity rather than the conventional RS-485 differential signaling convention. The SN65HVD96 series is an upgrade path for RS-485 installations, although the devices are not protocol-compatible with existing RS-485 networks. Key electrical features include a 4.75 V to 5.25 V supply range, one transmitter and one receiver, 5 Mbps signaling, 100 mV receiver hysteresis, and support for reversed-wire connections. The symmetric-polarity receiver helps the device interpret bus states consistently when conductors are connected in reverse. The 8-pin SOIC package also saves board area compared with equivalent discrete driver and receiver implementations. TI specifies an industrial operating range from -40 °C to 85 °C, making the device suitable for industrial instrumentation, factory automation, and commercial equipment that operates outside extended automotive temperature limits. The SOIC outline supports conventional surface-mount assembly, while the eight-pin footprint reduces the number of components needed to implement a robust bus node. Typical uses include industrial sensor networks, process-control equipment, remote monitoring stations, PLC peripheral interfaces, and point-to-point data links between controllers and field devices. Because the SN65HVD96D supports reversed wiring and 5 Mbps signaling, it is particularly useful where field installation errors or shorter, higher-speed interconnects are expected. The device pinout is identical to the industry-standard SN75176 transceiver, allowing an SN75176-based board to be considered for a SymPol migration. Existing RS-485 firmware and system behavior are not automatically compatible because SymPol is not backward compatible with RS-485, so the bus protocol and termination strategy must be reviewed before replacement. This page consolidates verified manufacturer and distributor information, package and pinout details, application guidance, and migration considerations that are not presented together on a standard distributor listing. Pricing and drop-in replacement availability are reported only where supported by verified source data.

SN65LBC176DR

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.

SN65LVDS105PWR

SN65LVDS105PWR - 1:4 LVDS Clock Fanout Buffer 400Mbps | TI

The Texas Instruments SN65LVDS105PWR is a 1 LVTTL-to-4 LVDS clock fanout buffer and repeater that accepts a single low-voltage TTL input and drives four differential LVDS output pairs at data signaling rates up to 400 Mbps (clock frequencies to 400 MHz), operating from a single 3.3-V supply (3 V to 3.6 V) in a 16-pin TSSOP (PW) package. A clock fanout buffer is a timing distribution device that takes one reference clock or data stream and replicates it across multiple identical outputs, maintaining signal integrity over transmission lines. Within the system hierarchy, it belongs to the clock buffer and signal repeater family of interface ICs, sitting between the clock source and the differential receivers distributed across a backplane or board. LVDS, as specified in ANSI EIA/TIA-644, is a low-voltage differential signaling technique offering low power, low noise coupling, and high switching speeds over relatively long distances. Key features include four differential LVDS line drivers meeting or exceeding the ANSI EIA/TIA-644 LVDS standard, a typical output voltage swing of 350 mV into a 100-ohm load, operation from a single 3.3-V rail, and support for signaling rates to 400 Mbps. The LVTTL-compatible input allows direct connection to standard CMOS or TTL clock sources without external level translation. Technically, the SN65LVDS105 integrates one LVTTL receiver stage followed by four parallel LVDS drivers implemented with current-mode outputs, which limit the slew-related EMI and crosstalk compared with single-ended signaling. The small 350-mV differential swing over a 100-ohm terminated line reduces power consumption relative to PECL while sustaining high data rates, making the part well suited to dense timing trees. Typical applications include clock distribution to backplane line cards, LVDS signal retiming and repeat in telecom and networking equipment, and fanout of a processor or FPGA reference clock to multiple serializer or ADC loads. Design consideration: route each LVDS output pair as a controlled-impedance 100-ohm differential pair, and keep the LVTTL input trace away from the LVDS pairs; on multilayer boards TI recommends at least two separate signal planes to reduce TTL/CMOS-to-LVDS crosstalk.

SN65LVDS105PWRG4

SN65LVDS105PWRG4 - 1:4 LVDS Clock Fanout Buffer 400Mbps | TI

The Texas Instruments SN65LVDS105PWRG4 is a 1 LVTTL-to-4 LVDS clock fanout buffer and repeater that supports data signaling rates up to 400 Mbps, operates from a single 3 V to 3.6 V supply, and is housed in a 16-pin TSSOP (PW) package. It accepts one low-voltage TTL (LVTTL) input and drives four differential LVDS output pairs that meet or exceed the ANSI EIA/TIA-644 LVDS standard. A clock fanout buffer is a timing-distribution component in the clock and timing hierarchy of a digital system. It takes a single reference clock (or data stream) and replicates it to multiple loads while preserving signal integrity, edge rate, and jitter performance. In LVDS-based systems, the fanout buffer also converts single-ended LVTTL levels to low-voltage differential signaling, which offers common-mode noise immunity and lower electromagnetic emissions than single-ended CMOS or TTL clock distribution. Key features of the SN65LVDS105 include compliance with the ANSI EIA/TIA-644 LVDS electrical standard, typical LVDS output swing of approximately 285 mV into a 100-ohm load, and bus-terminal ESD tolerance that exceeds 12 kV (per TI family datasheet information for this device class). The four LVDS drivers provide deterministic propagation delay with a typical buffer delay of 2.2 ns, enabling predictable multi-load clock skew planning. The device operates from a 3.3 V nominal supply (3 V to 3.6 V range), making it compatible with standard logic rails. The LVTTL receiver input accepts standard 3.3 V logic levels, so the part can sit directly between an FPGA, MCU, or clock generator output and four separate LVDS destinations such as displays, serializers, or data converters. The SN65LVDS104 companion variant accepts differential input levels (+/-100 mV typical) instead of LVTTL, allowing true LVDS repeater designs. Typical applications include backplane clock distribution, point-to-point LVDS data links, LCD panel timing distribution, telecom and networking line cards, and industrial control systems requiring 400 Mbps-class differential signaling over controlled-impedance traces. Design consideration: use 100-ohm differential termination at each LVDS receiver, keep the four output pairs tightly length-matched, and verify supply decoupling with 0.1 uF ceramic capacitors at each VCC pin to minimize jitter contribution.

SN65LVDS31D

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

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

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.

SN65LVDT100DGK

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.

SN65MLVD200ADR

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.

SN74ABT162841

SN74ABT162841 - 20-Bit Bus-Interface D-Type Latch | TI

The SN74ABT162841 is a 20-bit bus-interface D-type transparent latch with 3-state outputs, designed by Texas Instruments as part of the Widebus family. It features noninverting outputs and is optimized for driving highly capacitive or relatively low-impedance loads. The device operates from a 4.5V to 5.5V supply, with a typical propagation delay of 4.6 ns and output ground bounce below 0.8V at VCC = 5V and TA = 25°C. It is available in a 56-pin SSOP package (DL suffix) and a 56-pin TSSOP package (DLR suffix). A bus-interface D-type latch is a digital logic component that captures data on its D inputs when the latch enable (LE) signal is asserted, holding the data on its Q outputs until the next enable pulse. It is a fundamental building block in digital systems for temporary data storage, bus isolation, and signal synchronization. In the hierarchy of digital logic, it belongs to the category of latches, which are level-sensitive storage elements, as opposed to edge-triggered flip-flops. Latches are essential in microprocessor systems, memory interfaces, and data acquisition circuits where multiple data lines must be captured simultaneously. Key features of the SN74ABT162841 include 3-state outputs that allow connection to a shared bus without contention, a flow-through architecture that simplifies PCB layout, and distributed VCC and GND pins that minimize high-speed switching noise. The device also supports hot insertion with Ioff and power-up 3-state, and its latch-up performance exceeds 500 mA per JEDEC standards. The EPIC-B BiCMOS design significantly reduces power dissipation compared to bipolar logic, making it suitable for high-density systems. Technically, the SN74ABT162841 uses a BiCMOS process that combines the speed of bipolar transistors with the low power of CMOS. The outputs have equivalent 25-ohm series resistors, eliminating the need for external resistors in many applications. The device is characterized for operation from -40°C to 85°C, and it is RoHS compliant. The 3-state outputs are controlled by an output enable (OE) input, which places the outputs in a high-impedance state when asserted high, allowing multiple devices to share a bus. Typical applications include memory address latching, data bus buffering in microprocessor systems, and interface circuits for industrial control and telecommunications equipment. The wide operating voltage range and high drive capability make it ideal for 5V systems that require robust signal integrity. The flow-through pinout aligns inputs and outputs on opposite sides, simplifying board routing and reducing crosstalk. When designing with this device, ensure that the OE and LE inputs are properly driven to avoid bus contention. The 3-state outputs allow multiple latches to share a bus, but only one should be enabled at a time. Consider the propagation delay and setup/hold times when designing timing margins for high-speed applications.
