ISL83078EIUZA-T

RENESAS · Pre-ordered Chips · MSOP-8

ISL83078EIUZA-T from RENESAS, in a MSOP-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 ≥ -50mV, low if A-B ≤ -200mV, and high if A and B are unconnected (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 directly to GND or through a 1k to 3k resistor to GND.
3 DE input Driver output enable: the driver 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 output 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 level noninverting receiver input and noninverting driver output; it is an input when DE = 0 and an output when DE = 1.
7 B/Z bidirectional 15kV HBM ESD protected RS-485/RS-422 level inverting receiver input and inverting driver output; it 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.
