65HVD3085EIM

HGSEMI · RS-485/RS-422 ICs · SOIC-8

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.
