# THVD1510DGKR

**Texas Instruments** · RS-485 / RS-422 ICs · VSSOP-8-0.65mm

THVD1510DGKR from Texas Instruments, in a VSSOP-8-0.65mm. 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 | Receive data output; the Absolute Maximum Ratings give a receiver output current limit of -24 mA to 24 mA. |
| 2 | RE | input | Receiver enable, active low, with a 2 MΩ internal pull-up. |
| 3 | DE | input | Driver enable, active high, with a 2 MΩ internal pull-down. |
| 4 | D | input | Driver data input. |
| 5 | GND | power_in | Device ground. |
| 6 | A | bidirectional | Bus I/O port A, complementary to B; bus pins are rated -18 V to 18 V with respect to GND. |
| 7 | B | bidirectional | Bus I/O port B, complementary to A; bus pins are rated -18 V to 18 V with respect to GND. |
| 8 | VCC | power_in | 5-V supply; the recommended supply range is 4.5 V to 5.5 V and the absolute maximum is 7 V. |
