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. |
