MAX22290CASA+

Analog Devices Inc./Maxim Integrated · Digital Isolators · SOIC-8

MAX22290CASA+ from Analog Devices Inc./Maxim Integrated, 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 VDDA power_in Power supply input for Side A, specified at 1.71V to 5.5V relative to GNDA; bypass VDDA to GNDA with a 0.1µF ceramic capacitor as close as possible to the pin.
2 IN1 input Logic input 1 on Side A (MAX22290 pin 2 is IN1; the MAX22291 uses this pin for OUT1 instead).
3 IN2 input Logic input 2 on Side A.
4 GNDA power_in Ground reference for Side A; VDDA and the Side A logic levels are referenced to this pin.
5 GNDB power_in Ground reference for Side B; VDDB and the Side B logic levels are referenced to this pin.
6 OUT2 output Logic output 2 on Side B, push-pull driver that can drive TTL and CMOS inputs.
7 OUT1 output Logic output 1 on Side B, push-pull driver that can drive TTL and CMOS inputs.
8 VDDB power_in Power supply input for Side B, specified at 1.71V to 5.5V relative to GNDB; bypass VDDB to GNDB with a 0.1µF ceramic capacitor as close as possible to the pin.
