65HVD3085EIM from HGSEMI, 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 | RO | output | Receiver output: when RE is low, RO is high if A-B is not less than -50mV and low if A-B is not greater than -200mV. |
| 2 | RE | input | Receiver output enable: RO is active when RE is low and high-impedance when RE is high, and RE high with DE low puts the device in low-power shutdown; RE uses a hot-swap input structure. |
| 3 | DE | input | Driver output enable: the driver outputs are active when DE is high and high-impedance when DE is low, and DE uses a hot-swap input structure. |
| 4 | DI | input | Driver input: when DE is high, a low on DI drives output A/Y low and B/Z high, and a high on DI drives A/Y high and B/Z low. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Receiver non-inverting input and driver non-inverting output. |
| 7 | B | bidirectional | Receiver inverting input and driver inverting output. |
| 8 | VCC | power_in | Positive supply: 4.5V ≤ VCC ≤ 5.5V, with a 0.1µF capacitor to ground. |
