Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OUT | output | Output pin of comparator 1; it is an open-drain NPN pull-down whose logic-low voltage (VOL) is resistive and scales with output current. |
| 2 | 1IN- | input | Negative input pin of comparator 1; the voltage must not go below -0.3 V, and the common-mode range extends from ground to VCC-2 V over the full temperature range. |
| 3 | 1IN+ | input | Positive input pin of comparator 1; the voltage must not go below -0.3 V, and the common-mode range extends from ground to VCC-2 V over the full temperature range. |
| 4 | GND | power_in | Ground reference pin; all voltages except differential voltages are referenced to network ground. |
| 5 | 2IN+ | input | Positive input pin of comparator 2; the voltage must not go below -0.3 V, and the common-mode range extends from ground to VCC-2 V over the full temperature range. |
| 6 | 2IN- | input | Negative input pin of comparator 2; the voltage must not go below -0.3 V, and the common-mode range extends from ground to VCC-2 V over the full temperature range. |
| 7 | 2OUT | output | Output pin of comparator 2; it is an open-drain NPN pull-down whose logic-low voltage (VOL) is resistive and scales with output current. |
| 8 | VCC | power_in | Supply pin; the recommended supply range is 2 V to 30 V, with an absolute maximum of 36 V. |
