SN65LVDS9637D 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 | Supply voltage; recommended 3 V to 3.6 V (3.3 V nominal), absolute maximum supply range -0.5 V to 4 V. |
| 2 | 1Y | output | LVTTL output signal of receiver channel 1. |
| 3 | 2Y | output | LVTTL output signal of receiver channel 2. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | 2B | input | Differential (LVDS) inverting input of receiver channel 2; differential input thresholds are ±100 mV maximum. |
| 6 | 2A | input | Differential (LVDS) non-inverting input of receiver channel 2; differential input thresholds are ±100 mV maximum. |
| 7 | 1B | input | Differential (LVDS) inverting input of receiver channel 1; differential input thresholds are ±100 mV maximum. |
| 8 | 1A | input | Differential (LVDS) non-inverting input of receiver channel 1; differential input thresholds are ±100 mV maximum. |
