HX65HVD3085-S

ZHHXDZ · RS-485 / RS-422 ICs · SOP-8

HX65HVD3085-S from ZHHXDZ, in a SOP-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 data output: RO is high when A-B is at or above -50 mV and low when A-B is at or below -200 mV, and the receiver fail-safe holds RO high for open-circuit or short-circuit inputs.
2 RE input Receiver enable input: RO is active when RE is low and goes high-impedance when RE is high.
3 DE input Driver enable input: the driver is active when DE is high, and A/B are high-impedance when DE is low.
4 DI input Driver data input: with DE high, DI high drives A high and B low, and DI low drives A low and B high.
5 GND power_in Ground reference for the device; all voltages are referenced to ground.
6 A bidirectional Bus line A (non-inverting): driver differential output and receiver input, with a common-mode range of -7 V to +12 V.
7 B bidirectional Bus line B (inverting): driver differential output and receiver input, with a common-mode range of -7 V to +12 V.
8 VCC power_in Power supply, 4.5 V to 5.5 V (5 V ±5%) as stated in the DC characteristics.
