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. |
