ES3490EEUA from ElecSuper, in a MSOP-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 | VCC | power_in | Power supply pin; the device operates from a 3.0 V to 5.5 V supply, and the absolute maximum VCC is +7 V. |
| 2 | RO | output | Receiver output: goes high when A-B is at or above +200 mV and low when A-B is at or below -200 mV. |
| 3 | DI | input | Driver input: a low level drives Y low and Z high, and a high level drives Y high and Z low; DI input range is -0.3 V to VCC+0.3 V. |
| 4 | GND | power_in | Ground pin; all voltages on the device are referenced to this ground. |
| 5 | Y | output | Non-inverting driver output (bus side). |
| 6 | Z | output | Inverting driver output (bus side). |
| 7 | B | input | Receiver inverting input (bus side); bus-side input voltage range is -8 V to +13 V. |
| 8 | A | input | Receiver non-inverting input (bus side); bus-side input voltage range is -8 V to +13 V. |
