SN65HVD3085EDR 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; transitions high when differential input voltage VID exceeds positive threshold VIT+ and low when VID is below negative threshold VIT-. |
| 2 | RE | input | Receiver enable, active low; receiver output placed in high-impedance state when RE is high or open. |
| 3 | DE | input | Driver enable, active high; driver outputs placed in high-impedance state when DE is low. |
| 4 | D | input | Driver data input; logic high at D produces A output high and B output low when driver is enabled. |
| 5 | GND | power_in | Local device ground reference potential. |
| 6 | A | bidirectional | Differential bus line complementary to B; serves as driver output or receiver input with bus voltage range -7 V to 12 V. |
| 7 | B | bidirectional | Differential bus line complementary to A; serves as driver output or receiver input with bus voltage range -7 V to 12 V. |
| 8 | VCC | power_in | Supply voltage input rated 4.5 V to 5.5 V. |
