# ISL3176EIUZ

**RENESAS** · Pre-ordered Chips · MSOP-10

ISL3176EIUZ from RENESAS, in a MSOP-10. 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: RO is high if A-B is at or above -50mV, low if A-B is at or below -200mV, and high if A and B are floating or shorted. |
| 2 | RE | input | Receiver output enable: RO is enabled when RE is low and high impedance when RE is high; if the Rx enable function is not required, connect RE directly to GND or through a 1kΩ to 3kΩ resistor to GND. |
| 3 | DE | input | Driver output enable: outputs Y and Z are enabled when DE is high and high impedance when DE is low; if the Tx enable function is not required, connect DE to VCC through a 1kΩ to 3kΩ resistor. |
| 4 | DI | input | Driver input: a low on DI forces Y low and Z high, and a high on DI forces Y high and Z low. |
| 5 | GND | power_in | Ground connection. |
| 6 | Y | output | ±15kV IEC61000 ESD protected RS-485/422 level, noninverting driver output. |
| 7 | Z | output | ±15kV IEC61000 ESD protected RS-485/422 level, inverting driver output. |
| 8 | B | input | ±15kV IEC61000 ESD protected RS-485/422 level, inverting receiver input. |
| 9 | A | input | ±15kV IEC61000 ESD protected RS-485/422 level, noninverting receiver input. |
| 10 | VCC | power_in | System power supply input, 3.0V to 3.6V. |
