# THVD1512DGS

**Texas Instruments** · RS-485 / RS-422 ICs · VSSOP-10-0.5mm

THVD1512DGS from Texas Instruments, in a VSSOP-10-0.5mm. 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; the datasheet gives no further electrical limit for this pin. |
| 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 | Y | output | Bus output Y, complementary to Z. |
| 7 | Z | output | Bus output Z, complementary to Y. |
| 8 | B | input | Bus input/output pin B, complementary to A; the bus pins withstand ±18 V (absolute maximum, common-mode or differential, with respect to GND) and ±30 kV HBM ESD. |
| 9 | A | input | Bus input/output pin A, complementary to B; the bus pins withstand ±18 V (absolute maximum, common-mode or differential, with respect to GND) and ±30 kV HBM ESD. |
| 10 | VCC | power_in | 5-V supply; the datasheet specifies 4.5 V to 5.5 V operation. |
