SN65HVD1477DR

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

SN65HVD1477DR 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-V to 3.6-V supply voltage input.
2 R output Receive data output from the differential receiver.
3 D input Driver data input to the differential driver.
4 GND power_in Local device ground reference potential.
5 Y output Digital bus output, Y (Complementary to Z) from the differential driver.
6 Z output Digital bus output, Z (Complementary to Y) from the differential driver.
7 B input Digital bus input, B (Complementary to A) to the differential receiver.
8 A input Digital bus input, A (Complementary to B) to the differential receiver.
