SN65HVD96D - 5 Mbps SymPol Transceiver | Texas Instruments
부품 번호: SN65HVD96D ✓ 활성SN65HVD96D 개요
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.

Industrial Sensor Networks
The SN65HVD96D fits industrial sensor networks that connect field sensors to a controller over a short, high-speed bus. Its 5 Mbps maximum signaling rate supports modern digital sensor data, while the -40 °C to 85 °C operating range suits factory-floor equipment. Symmetric-polarity reception and 100 mV hysteresis improve state recognition, and reversed-wire communication reduces the impact of installation errors. Because the device is not isolated, engineers should still verify common-mode limits, grounding, and protection for the cable length used.
추천
Factory Automation and PLC Peripherals
The SN65HVD96D is suitable for point-to-point and multi-drop factory automation links where a controller connects to remote I/O modules. The 5 V supply simplifies integration with conventional logic rails, and the 8-pin SOIC package reduces board area compared with a discrete driver and receiver. Signaling up to 5 Mbps permits short, deterministic links between control boards and peripheral modules. SymPol is not backward compatible with RS-485, however, so existing PLC nodes must be converted or verified rather than mixed indiscriminately on the same bus.
추천
Process-Control and Monitoring Equipment
The SN65HVD96D can connect monitoring instruments, controllers, and remote I/O in process-control equipment where symmetric bus polarity improves installation robustness. Its 100 mV receiver hysteresis provides a defined transition region, while operation on normal or reversed conductors helps when field wiring cannot be visually inspected. The -40 °C to 85 °C range supports industrial environments, but the non-isolated interface requires careful attention to ground potential differences and surge exposure. Cable length, stub effects, and grounding should be checked against the manufacturer's system guidelines.
추천
Point-to-Point Data Links
For short point-to-point links between two circuit boards, the SN65HVD96D provides a combined driver and receiver in one 8-SOIC device. The maximum 5 Mbps signaling rate supports high-rate control or status data over appropriately short connections. Symmetric-polarity signaling and reversed-wire tolerance make the interface less sensitive to physical installation errors than a basic driver-receiver arrangement. Because SymPol does not replace RS-485 at the protocol level, both endpoint devices and the host firmware must support the same signaling convention before the link is deployed.
추천
Remote Equipment Communication
The SN65HVD96D is applicable to remote monitoring units and equipment interfaces that require reliable communication over field wiring. Reversed-wire operation helps when conductors may be connected in the opposite order, and the 5 V supply range matches common control-board rails. The industrial temperature rating supports unheated enclosures and industrial environments. For installations spanning large ground-potential differences or exposed to severe surge transients, external protection and an isolated interface should be evaluated; the verified data does not establish the SN65HVD96D as an isolated or AEC-Q100-qualified device.
추천
Instrumentation and Test Systems
The SN65HVD96D can connect laboratory and industrial instrumentation modules that exchange measurements over a short multi-point bus. Its 5 Mbps maximum rate accommodates high-resolution digital measurement data, while symmetric polarity and 100 mV hysteresis support dependable state detection. The 8-SOIC package allows compact implementation in multi-channel instruments. Designers should use the manufacturer's recommended bus topology and consider isolation for bench systems where test-equipment ground offsets may exist. SymPol-specific endpoints are required because the protocol is not compatible with conventional RS-485 nodes.

설계 노트
Do not treat the SN65HVD96D as a protocol-compatible SN75176 replacement even though Texas Instruments confirms an identical pin-out. SymPol is not backward compatible with RS-485, so a converted board must use SymPol endpoints and compatible host firmware. Reuse of the PCB footprint is reasonable; automatic reuse of network behavior, termination settings, and system test procedures is not.
Place the transceiver close to the bus connector and route the A and B conductors as a pair to minimize differential-noise pickup. Keep the supply bypass capacitor close to the VCC pin and provide a short, low-inductance ground return. The verified data does not provide exact termination or protection component values, so use the manufacturer's system guidelines rather than assuming standard RS-485 network values.
The SN65HVD96D operates from 4.75 V to 5.25 V, so the host rail must remain within that range during startup and load transients. Provide local supply bypassing and verify that the 5 V source can support the combined driver and receiver load. Because the verified results do not specify quiescent current, driver output current, or package power dissipation, those limits must be taken from the official datasheet before a thermal or power-budget sign-off.
The symmetric-polarity receiver and 100 mV hysteresis are valuable on field-wired industrial buses, but they do not eliminate the need for correct topology. Keep stub lengths short, avoid unnecessary branch points, and confirm that the intended network is point-to-point, multi-drop, or multi-point as supported by the device. Reversed-wire tolerance improves installation resilience; it is not a substitute for surge protection or a sound grounding strategy.
규정 준수 정보
The verified SN65HVD96D specification listing identifies the device as lead free. No explicit RoHS, REACH, halogen-free, conflict-minerals, or AEC-Q100 statement was included in the supplied data, so those fields remain unknown.
