AMC22C12DR from Texas Instruments, 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 | VDD1 | power_in | High-side power supply, specified at 3V to 27V in the recommended range, with an absolute maximum of 30V (VDD1 to GND1, -0.3V to 30V). |
| 2 | IN | input | Analog input to the window comparator, with an absolute maximum range of -6V to 5.5V (IN to GND1). |
| 3 | REF | input | Reference pin that sets the trip threshold through a resistor to GND1 and is filtered by a capacitor to GND1; it is driven by an internal 100μA current source, can also be driven by an external voltage, and has an absolute maximum of -0.5V to 6.5V (REF to GND1). |
| 4 | GND1 | power_in | High-side ground reference for the isolated input side of the device. |
| 5 | GND2 | power_in | Low-side ground reference for the output side and the LATCH input of the device. |
| 6 | OUT | output | Open-drain output of the window comparator that must be connected to an external pullup resistor; its absolute maximum range is -0.5V to VDD2 + 0.5V (OUT to GND2). |
| 7 | LATCH | input | Digital input that selects latch mode (high) or transparent mode (low) of the open-drain output; it must not be left floating and should be connected to GND2 when not used, with an absolute range of -0.5V to VDD2 + 0.5V. |
| 8 | VDD2 | power_in | Low-side power supply, specified at 2.7V to 5.5V in the recommended range, with an absolute maximum of 6.5V (VDD2 to GND2). |
