SP3077EEN-L from MaxLinear, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Positive supply voltage 3.3V ±0.3V; bypass to GND with 0.1µF capacitor. |
| 2 | RO | output | Receiver output; high when differential input (A-B) ≥ -50mV, low when (A-B) ≤ -200mV. |
| 3 | DI | input | Driver input; low forces noninverting output (Y) low and inverting output (Z) high, high forces Y high and Z low. |
| 4 | GND | power_in | Ground. |
| 5 | Y | output | Noninverting driver output; voltage range -8V to +13V with ±15kV ESD protection. |
| 6 | Z | output | Inverting driver output; voltage range -8V to +13V with ±15kV ESD protection. |
| 7 | B | input | Inverting receiver input; voltage range -8V to +13V with ±15kV ESD protection and 96kΩ input impedance. |
| 8 | A | input | Noninverting receiver input; voltage range -8V to +13V with ±15kV ESD protection and 96kΩ input impedance. |
