# ISL83077EIBZA

**RENESAS** · Pre-ordered Chips · SOIC-8

ISL83077EIBZA from RENESAS, in a SOIC-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 | System power supply input, 3.0V to 3.6V. |
| 2 | RO | output | Receiver output: high if A - B >= -50mV, low if A - B <= -200mV, and high if A and B are floating or shorted. |
| 3 | DI | input | Driver input: a low forces Y low and Z high, a high forces Y high and Z low. |
| 4 | GND | power_in | Ground connection. |
| 5 | Y | output | 15kV HBM ESD protected RS-485/RS-422 level noninverting driver output. |
| 6 | Z | output | 15kV HBM ESD protected RS-485/RS-422 level inverting driver output. |
| 7 | B | input | 15kV HBM ESD protected RS-485/RS-422 level inverting receiver input. |
| 8 | A | input | 15kV HBM ESD protected RS-485/RS-422 level noninverting receiver input. |
