Product details

RS422/RS485 half-duplex transceiver — what this part is

It integrates one differential driver and one differential receiver, both active on the same twisted-pair bus, with a 50 mV receiver hysteresis for noise rejection on long cable runs.

5V-only supply — what it means for a replacement search

The SN65176BD is a 5V-only transceiver: the supply range of 4.75V to 5.25V means it cannot be powered from a 3.3V rail without a regulator. Any pin-compatible replacement must also accept a nominal 5V supply and maintain the same half-duplex, 1/1 driver/receiver configuration. The 50 mV receiver hysteresis is a typical value for this family — a replacement with lower hysteresis may be more susceptible to bus reflections on long stubs.

Frequently asked questions

What is the replacement for the SN65176BD?

No official TI replacement part number is listed for the SN65176BD. A functionally equivalent replacement must be a half-duplex RS422/RS485 transceiver in an 8-SOIC package, operating from a 5V supply, with one driver and one receiver. Parts like the TI SN65HVD72 or SN65HVD3082E are in the same family but differ in supply range or pinout — verify compatibility against the original footprint and bus timing before substituting.

Is the SN65176BD compatible with 5V RS485 systems?

Yes. The SN65176BD is designed for 5V RS485 and RS422 buses, with a supply range of 4.75V to 5.25V. It is a half-duplex transceiver with 50 mV receiver hysteresis, suitable for differential communication over twisted-pair cables in industrial environments.
