RENESAS · Interface - Specialized · SOIC-16

ISL32273EIBZ-T from RENESAS, in a SOIC-16. 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 B1 input ±16.5kV IEC61000-4-2 ESD protected RS-485/422 level, Channel 1 inverting receiver input.
2 A1 input ±16.5kV IEC61000-4-2 ESD protected RS-485/422 level, Channel 1 noninverting receiver input.
3 RO1 tri_state Channel 1 tristate receiver output: high if A1-B1 ≥ 200mV or floating, low if A1-B1 ≤ -200mV.
4 EN input Active high group enable input, receiver outputs enabled when high, internally pulled to VCC.
5 RO2 tri_state Channel 2 tristate receiver output: high if A2-B2 ≥ 200mV or floating, low if A2-B2 ≤ -200mV.
6 A2 input ±16.5kV IEC61000-4-2 ESD protected RS-485/422 level, Channel 2 noninverting receiver input.
7 B2 input ±16.5kV IEC61000-4-2 ESD protected RS-485/422 level, Channel 2 inverting receiver input.
8 GND power_in Ground connection and device circuit reference potential.
9 B3 input ±16.5kV IEC61000-4-2 ESD protected RS-485/422 level, Channel 3 inverting receiver input.
