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. |
