SN75HVD3082EDR 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 | Receive data output, reflects receiver input state when enabled. |
| 2 | RE | input | Receiver enable input, active low. |
| 3 | DE | input | Driver enable input, active high, controls A and B output behavior. |
| 4 | D | input | Driver data input, determines A and B differential state when driver enabled. |
| 5 | GND | power_in | Local device ground reference. |
| 6 | A | tri_state | Differential bus terminal A, output when driver enabled or input when receiver enabled. |
| 7 | B | tri_state | Differential bus terminal B, output when driver enabled or input when receiver enabled. |
| 8 | VCC | power_in | Power supply input, 4.5 V to 5.5 V. |
