HX65LBC182-S

ZHHXDZ · RS-485 / RS-422 ICs · SOP-8

HX65LBC182-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, which is driven low when the receiver differential input A-B is -200mV and high for -50mV, open circuit, or short circuit (fail-safe), with RE low.
2 RE input Receiver output enable, active low: with RE low the receiver is enabled, and with RE high RO is set to high impedance (Z).
3 DE input Driver output enable, active high: with DE high the chip operates in transmit mode, and with DE low the driver outputs A and B are high impedance (Z).
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.
6 A bidirectional Driver differential output and receiver differential input (non-inverting bus line A), rated ±15kV ESD HBM per the datasheet.
7 B bidirectional Driver differential output and receiver differential input (inverting bus line B), rated ±15kV ESD HBM per the datasheet.
8 Vcc power_in Power supply; the datasheet specifies a working voltage of 4.5 V to 5.5 V (5 V ±5%).
