HX65176-S

ZHHXDZ · RS-485 / RS-422 ICs · SOP-8

HX65176-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; driven high when A-B is at or above -50 mV, low when A-B is at or below -200 mV, and high for open or shorted receiver inputs (fail-safe).
2 RE input Receiver enable, active low: the receiver is enabled when RE is low and its output goes to high impedance when RE is high (per the truth table, RE high with DE low puts RO in high-impedance state).
3 DE input Driver enable, active high: the driver is enabled when DE is high and A/B go to high impedance when DE is low; the datasheet's truth table shows DE low with RE low places the chip in receive mode.
4 DI input Driver data input; sets the differential output on A/B when the driver is enabled (DI high gives A high / B low, DI low gives A low / B high).
5 GND power_in Ground reference for the device; all voltages are referenced to ground.
6 A bidirectional Driver differential output and receiver differential input (non-inverting bus line); ESD protected to ±15 kV human body model.
7 B bidirectional Driver differential output and receiver differential input (inverting bus line); ESD protected to ±15 kV human body model.
8 Vcc power_in Power supply, 5 V nominal; working voltage range 4.5 V to 5.5 V (5 V ±5%).
