XD3485

XINLUDA · RS-485 / RS-422 ICs · DIP-8

XD3485 from XINLUDA, in a DIP-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: when /RE is low, RO is high if A-B is at or above +200 mV and low if A-B is at or below -200 mV.
2 RE input Receiver output enable, active low: RO is active when /RE is low and high-impedance when /RE is high; with /RE high and DE low the device enters low-power shutdown.
3 DE input Driver output enable, active high: the driver output is active when DE is high and highly resistive when DE is low; with /RE high and DE low the device enters low-power shutdown.
4 DI input Driver input: when DE is high, a low on DI drives output A low and B high, and a high on DI drives A high and B low.
5 GND power_in Ground; the reference point for all voltages on the device.
6 A bidirectional Receiver non-inverting input and driver non-inverting output on the bus; bus-side input voltage is limited to -7 V to 13 V.
7 B bidirectional Receiver inverting input and driver inverting output on the bus; bus-side input voltage is limited to -7 V to 13 V.
8 VCC power_in Power supply, 3.3 V nominal with a stated operating range of 3.0 V to 3.6 V; absolute maximum supply voltage is +7 V.
