# SN65HVD30MDREP

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

SN65HVD30MDREP 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 | Power supply pin; the datasheet specifies 3 V to 3.6 V. |
| 2 | R | output | Receiver data output that reports the state of the differential bus input A/B. |
| 3 | D | input | Driver data input that sets the differential state of the Y/Z bus outputs. |
| 4 | GND | power_in | Local device ground reference. |
| 5 | Y | output | Bus driver output, complementary to Z. |
| 6 | Z | output | Bus driver output, complementary to Y. |
| 7 | B | input | Receiver bus input, complementary to A. |
| 8 | A | input | Receiver bus input, complementary to B. |
