HX65LBC184-S

ZHHXDZ · RS-485 / RS-422 ICs · SOP-8

HX65LBC184-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 output: RO goes high when A-B is at or above -50mV and goes low when A-B is at or below -200mV.
2 RE input Receiver output enable, active low: when RE is high the receiver is turned off, and when RE is high with DE low the whole chip enters shutdown.
3 DE input Driver output enable, active high: when DE is high the driver output is enabled, and when DE is low the driver turns off and the output enters a high-resistance state.
4 DI input Driver data input: when DI is high, A is high and B is low; when DI is low, A is low and B is high (per the drive truth table).
5 GND power_in Ground pin for the device.
6 A bidirectional Non-inverting driver output A and receiver input A; all driver outputs are rated for ±15kV human-body-model ESD protection.
7 B bidirectional Inverting driver output B and receiver input B; all driver outputs are rated for ±15kV human-body-model ESD protection.
8 VCC power_in Supply pin for 3.3V/5V operation; the absolute maximum supply rating printed in the datasheet is +6.0V.
