SN65HVD379DR

Texas Instruments · RS-485 / RS-422 ICs · SOIC-8

SN65HVD379DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in 3.3-V supply input, recommended operating range 3 V to 3.6 V (absolute maximum 6 V).
2 R output Receiver output, high when VID ≥ 0.2 V and low when VID ≤ -0.2 V, rated for ±8 mA recommended output current.
3 D input Driver input, 5-V tolerant, with high-level input of 2 V to VCC and low-level input of 0 to 0.8 V; an open input drives Y low and Z high.
4 GND power_in Ground reference for the device and the network ground terminal.
5 Y output Non-inverting RS-485/RS-422 driver output, with bus-fault protection from -7 V to 12 V.
6 Z output Inverting RS-485/RS-422 driver output, with bus-fault protection from -7 V to 12 V.
7 B input Inverting differential receiver input (1/2 unit load), with bus-fault protection from -7 V to 12 V.
8 A input Non-inverting differential receiver input (1/2 unit load), with bus-fault protection from -7 V to 12 V.
