Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OUT | output | Open-drain NPN output of comparator 1 that sinks current when 1IN+ is higher than 1IN- plus the offset voltage; absolute maximum output current is 18 mA, output pin voltage range is -0.3 V to 36 V, and output short to ground is unlimited. |
| 2 | 1IN- | input | Inverting (negative) input of comparator 1; the voltage must not go below -0.3 V, the absolute input pin range is -0.3 V to 36 V, and the common-mode range is 0 to VCC-1.5 V at 25 °C (0 to VCC-2 V over full temperature range). |
| 3 | 1IN+ | input | Non-inverting (positive) input of comparator 1; the voltage must not go below -0.3 V, the absolute input pin range is -0.3 V to 36 V, and the common-mode range is 0 to VCC-1.5 V at 25 °C (0 to VCC-2 V over full temperature range). |
| 4 | GND | power_in | Ground reference pin; all voltages on the device are referenced to network ground. |
| 5 | 2IN+ | input | Non-inverting (positive) input of comparator 2; the voltage must not go below -0.3 V, the absolute input pin range is -0.3 V to 36 V, and the common-mode range is 0 to VCC-1.5 V at 25 °C (0 to VCC-2 V over full temperature range). |
| 6 | 2IN- | input | Inverting (negative) input of comparator 2; the voltage must not go below -0.3 V, the absolute input pin range is -0.3 V to 36 V, and the common-mode range is 0 to VCC-1.5 V at 25 °C (0 to VCC-2 V over full temperature range). |
| 7 | 2OUT | output | Open-drain NPN output of comparator 2 that sinks current when 2IN+ is higher than 2IN- plus the offset voltage; absolute maximum output current is 18 mA, output pin voltage range is -0.3 V to 36 V, and output short to ground is unlimited. |
| 8 | VCC | power_in | Supply pin; recommended supply range is 2 V to 30 V (absolute maximum 36 V), and the device also supports dual supplies of ±18 V. |
