HX83483-S

ZHHXDZ · RS-485 / RS-422 ICs · SOP-8

HX83483-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: goes high when V(A)-V(B) is at or above -50 mV and low when V(A)-V(B) is at or below -200 mV, and is enabled when RE is low.
2 RE input Receiver output enable, active low: when RE is high the receiver is turned off, and when RE is high and DE is low the whole chip is turned off.
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 input: when DI is high, A is driven high and B low, and when DI is low, A is driven low and B high.
5 GND power_in Ground.
6 A bidirectional Non-inverting bus pin serving as the driver output and receiver input; the bus voltage limits are given in the absolute maximum table (A,B: -8.0 V to +13.0 V).
7 B bidirectional Inverting bus pin serving as the driver output and receiver input; the bus voltage limits are given in the absolute maximum table (A,B: -8.0 V to +13.0 V).
8 VCC power_in Supply voltage of 3.3V/5V; the DC characteristics are specified at Vcc = +3.3V ±5%, and the absolute maximum VCC is +6.0 V.
