# SN65HVD07DR

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

SN65HVD07DR 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 | R | output | Receiver data output, driven from the differential receiver inputs A and B as shown in the logic diagram. |
| 2 | RE | input | Receiver enable, active-low, so the receiver is enabled when this pin is held low (the datasheet states the receiver enables are active-low). |
| 3 | DE | input | Driver enable, active-high, so the driver is enabled when this pin is held high (the datasheet states the driver enables are active-high). |
| 4 | D | input | Driver data input that drives the differential A and B bus outputs when the driver is enabled, per the logic diagram. |
| 5 | GND | power_in | Ground reference pin for the device; no voltage limits for this pin are given in the pages provided. |
| 6 | A | bidirectional | Non-inverting bus pin of the differential I/O port, shared by the driver output and receiver input. |
| 7 | B | bidirectional | Inverting bus pin of the differential I/O port, shared by the driver output and receiver input, designed to offer minimum bus loading when the driver is disabled or unpowered. |
| 8 | VCC | power_in | Positive supply pin; the recommended supply voltage range is not stated in the pages provided. |
