HX83088-S

ZHHXDZ · RS-485 / RS-422 ICs · SOP-8

HX83088-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 more, low when A-B is -200 mV or less, and high-impedance when RE is high and DE is high.
2 RE input Receiver output enable, active low: the receiver is enabled when RE is low and RO goes high-impedance when RE is high (inferred from the truth table; the source text for this pin is partly garbled).
3 DE input Driver output enable, active high: when DE is high the driver drives A and B according to DI, and when DE is low A and B are high-impedance.
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 Non-inverting driver output and receiver input bus terminal, rated ESD ±15 kV (HBM) on A/B; receiver input impedance is 1/8 unit load (RIN 96 kΩ minimum).
7 B bidirectional Inverting driver output and receiver input bus terminal, rated ESD ±15 kV (HBM) on A/B; receiver input impedance is 1/8 unit load (RIN 96 kΩ minimum).
8 VCC power_in Power supply, 4.5 V to 5.5 V (5 V nominal); absolute maximum is 6.0 V.
