THVD1550DGKR from Texas Instruments, in a VSSOP-8-0.65mm. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | R | output | Receive data output, active high from the differential receiver. |
| 2 | RE | input | Receiver enable input, active low with 2 MΩ internal pull-up resistor. |
| 3 | DE | input | Driver enable input, active high with 2 MΩ internal pull-down resistor. |
| 4 | D | input | Driver data input for the differential driver. |
| 5 | GND | power_in | Device ground reference. |
| 6 | A | bidirectional | Differential bus I/O port A (complementary to B) with extended operational common-mode range of ±15 V. |
| 7 | B | bidirectional | Differential bus I/O port B (complementary to A) with extended operational common-mode range of ±15 V. |
| 8 | VCC | power_in | 5-V supply voltage (4.5 V to 5.5 V nominal operating range). |
