HX3088-S

ZHHXDZ · RS-485 / RS-422 ICs · SOP-8

HX3088-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 datasheet's receiver truth table shows RO high for A-B >= -50 mV and low for A-B <= -200 mV, with open or short circuit inputs giving RO high.
2 RE input Receiver enable, active low: the receiver is enabled when RE is low and its output is high-impedance when RE is high (with DE high or low), per the truth table.
3 DE input Driver enable, active high: the chip is in transmit mode when DE is high, and in receive mode when DE is low and RE is low, per the datasheet's operating-mode text.
4 DI input Driver data input that sets the differential driver output on A and B when the driver is enabled.
5 GND power_in Ground reference for the device; the datasheet states all voltages are referenced to ground.
6 A bidirectional Driver differential output (A) and receiver differential input (A), with ±15 kV Human Body Model ESD protection between A and B.
7 B bidirectional Driver differential output (B) and receiver differential input (B), with ±15 kV Human Body Model ESD protection between A and B.
8 VCC power_in Power supply, specified at 4.5 V to 5.5 V (5 V ±5%) for the working voltage range.
