HGX3485EIM from HGSEMI, 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: with /RE low, RO goes high when A-B is at or above +200 mV and goes low when A-B is at or below -200 mV. |
| 2 | /RE | input | Active-low receiver output enable: a high level puts RO in high impedance, and /RE high with DE low puts the device into low-power shutdown. |
| 3 | DE | input | Driver output enable: a high level enables the driver outputs and a low level puts them in high impedance; with /RE high and DE low the device enters shutdown. |
| 4 | DI | input | Driver input: while DE is high, a low on DI drives A low and B high, and a high on DI drives A high and B low. |
| 5 | GND | power_in | Ground reference for the device; all voltages are referenced to this pin. |
| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output on the RS-485 bus. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output on the RS-485 bus; bus-side input voltage is rated -7 V to +13 V. |
| 8 | VCC | power_in | Supply pin; the device operates from 3.0 V to 3.6 V (3.3 V ±10%), with an absolute maximum supply of +7 V. |
