HX483-S

ZHHXDZ · RS-485 / RS-422 ICs · SOP-8

HX483-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; per the receiver truth table it is high when A-B is -50 mV or an open/short circuit at the input, and low when A-B is -200 mV.
2 RE input Receiver output enable; the receiver is active when RE is low and RO goes to high impedance (Z) when RE is high.
3 DE input Driver output enable; the driver is active when DE is high and A/B go to high impedance (Z) 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.
6 A bidirectional Driver data output and receiver data input (non-inverting bus line A); rated for ±15 kV HBM ESD protection.
7 B bidirectional Driver data output and receiver data input (inverting bus line B); rated for ±15 kV HBM ESD protection.
8 Vcc power_in Power supply; the working voltage range is 4.5 V to 5.5 V (5 V ±5%).
