ASL485S-R

ASDsemi · RS-485 / RS-422 ICs · SOP-8

ASL485S-R from ASDsemi, 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: while /RE is low, RO goes high when A - B ≥ -50 mV and goes low when A - B ≤ -200 mV.
2 /RE input Receiver output enable, active low: driving /RE low enables RO, and RO is high impedance when /RE is high; /RE high with DE low puts the device into low-power shutdown.
3 DE input Driver output enable: driving DE high enables the driver outputs, which are high impedance when DE is low; DE low with /RE high puts the device into low-power shutdown.
4 DI input Driver input: with DE high, a low on DI forces the noninverting output (A) low and the inverting output (B) high.
5 GND power_in Ground reference for the device.
6 A bidirectional Noninverting receiver input and noninverting driver output; receiver input resistance is at least 96 kΩ for -7 V ≤ VCM ≤ 12 V.
7 B bidirectional Inverting receiver input and inverting driver output; receiver input resistance is at least 96 kΩ for -7 V ≤ VCM ≤ 12 V.
8 VCC power_in Positive supply; the absolute maximum VCC is +7 V, and the electrical characteristics are specified at VCC = 5 V.
