HX65HVD3088-S

ZHHXDZ · RS-485 / RS-422 ICs · SOP-8

HX65HVD3088-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; the receiver truth table gives RO high for A-B at or above -50 mV, low for A-B at or below -200 mV, and high for open or shorted inputs, and it is high-Z when RE is high and DE is low.
2 RE input Receiver output enable, active low (printed with an overline); the datasheet pin table says that when RE is high the receiver output is high.
3 DE input Driver output enable, active high; the datasheet states that outputs A and B are high-Z when DE is low.
4 DI input Driver data input; DI drives the A/B differential outputs, with input high voltage of 2 V minimum and input low voltage of 0.8 V maximum.
5 GND power_in Ground reference; the datasheet states all voltages are referenced to ground.
6 A bidirectional Driver differential output and receiver differential input (non-inverting bus line); A/B ESD protection is ±15 kV HBM and up to 256 transceivers may share the bus.
7 B bidirectional Driver differential output and receiver differential input (inverting bus line); A/B ESD protection is ±15 kV HBM and up to 256 transceivers may share the bus.
8 VCC power_in Supply pin; operating range 4.5 V to 5.5 V (Vcc = 5 V ±5%), with absolute maximum 6.0 V.
