RENESAS · RS-485 / RS-422 ICs · SOIC-8

ISL83072EIBZA-T 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 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 unused, connect RE to GND directly or through a 1k to 3k resistor.
3 DE input Driver output enable: outputs Y and Z are enabled when DE is high and high-impedance when DE is low; if unused, connect DE to VCC through a 1k to 3k 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 A/Y bidirectional 15kV HBM ESD-protected RS-485/RS-422 noninverting receiver input and noninverting driver output; the pin is an input when DE = 0 and an output when DE = 1.
7 B/Z bidirectional 15kV HBM ESD-protected RS-485/RS-422 inverting receiver input and inverting driver output; the pin is an input when DE = 0 and an output when DE = 1.
8 VCC power_in System power supply input, 3.0V to 3.6V.
