ISL3176EIUZ-T

Intersil(Renesas Electronics) · RS-485/RS-422 ICs · MSOP-10

ISL3176EIUZ-T from Intersil(Renesas Electronics), 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 tri_state Receiver output: high if A-B ≥ -50mV, low if A-B ≤ -200mV, and high if A and B are floating or shorted; high impedance when RE is high.
2 RE input Receiver output enable: RO is enabled when RE is low and high impedance when RE is high; if unused, connect to GND directly or through a 1kΩ to 3kΩ resistor.
3 DE input Driver output enable: Y and Z are enabled when DE is high and high impedance when DE is low; if unused, connect to VCC through a 1kΩ to 3kΩ resistor.
4 DI input Driver input: a low forces Y low and Z high, a high forces Y high and Z low.
5 GND power_in Ground connection.
6 Y tri_state ±15kV IEC61000 ESD protected RS-485/422 level noninverting driver output.
7 Z tri_state ±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).
