## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Comparator output, which is push-pull per the datasheet features. |
| 2 | V- | power_in | Negative supply voltage; VS = (V+) - (V-) is specified at 2.7 V to 5.5 V, and the input voltage range extends to (V-) - 0.1 V. |
| 3 | IN+ | input | Non-inverting (+) input; the input voltage range is (V-) - 0.1 V to (V+) + 0.1 V, and input current is limited to 10 mA maximum. |
| 4 | IN- | input | Inverting (-) input; the input voltage range is (V-) - 0.1 V to (V+) + 0.1 V, and input current is limited to 10 mA maximum. |
| 5 | V+ | power_in | Positive supply voltage; VS = (V+) - (V-) is specified at 2.7 V to 5.5 V, with an absolute maximum of 6 V. |
