ADUM1201ARZ-JSM

JSMSEMI · Digital Isolators · SOP-8

ADUM1201ARZ-JSM from JSMSEMI, in a SOP-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 VIA input Logic input for channel A (Side 1); VIH = 0.7×VDD1, VIL = 0.3×VDD1; drives VOA on Side 2.
2 GND1 power_in Ground reference for Side 1 (input side); 0V reference for VDD1 and all Side-1 signals.
3 VDD1 power_in Supply voltage for Side 1; operating range 2.5V to 5.5V; absolute maximum 6V.
4 VIB input Logic input for channel B (Side 1); VIH = 0.7×VDD1, VIL = 0.3×VDD1; drives VOB on Side 2.
5 VOB output Logic output for channel B (Side 2); default output state is high when VDD1 or VDD2 is unpowered (ARZ default-high variant).
6 VDD2 power_in Supply voltage for Side 2; operating range 2.5V to 5.5V; absolute maximum 6V.
7 GND2 power_in Ground reference for Side 2 (output side); 0V reference for VDD2 and all Side-2 signals.
8 VOA output Logic output for channel A (Side 2); default output state is high when VDD1 or VDD2 is unpowered (ARZ default-high variant).
