Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OUT | output | Channel 1 comparator output is an uncommitted grounded-emitter NPN collector that can sink up to about 16 mA, with output voltage rated to 36 V. |
| 2 | 1IN- | input | Channel 1 inverting input; the input must not go below -0.3 V (at +25 °C), and either input can go to +36 V without damage. |
| 3 | 1IN+ | input | Channel 1 non-inverting input; the common-mode range is 0 V to VCC - 1.5 V at +25 °C and the input must not go below -0.3 V. |
| 4 | GND | power_in | Ground reference pin; all electrical characteristics are specified with GND = 0 V. |
| 5 | 2IN+ | input | Channel 2 non-inverting input; the common-mode range is 0 V to VCC - 1.5 V at +25 °C and the input must not go below -0.3 V. |
| 6 | 2IN- | input | Channel 2 inverting input; the input must not go below -0.3 V (at +25 °C), and either input can go to +36 V without damage. |
| 7 | 2OUT | output | Channel 2 comparator output is an uncommitted grounded-emitter NPN collector that can sink up to about 16 mA, with output voltage rated to 36 V. |
| 8 | VCC | power_in | Chip supply voltage; single-supply operation is specified from 2 V to 36 V (absolute maximum 36 V). |
