## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTPUT1 | output | Open-collector output of comparator 1; the datasheet gives a saturation voltage of 200 mV typical at 4 mA sink and a sink current of 6.0 mA minimum. |
| 2 | INPUT1- | input | Inverting input of comparator 1; the common-mode range is 0 V to VCC-1.5 V and the input can be driven up to +36 V without damage, but should not go below -0.3 V. |
| 3 | INPUT1+ | input | Non-inverting input of comparator 1; the common-mode range is 0 V to VCC-1.5 V and the input can be driven up to +36 V without damage, but should not go below -0.3 V. |
| 4 | GND | power_in | Ground reference (0 V) for the device; the datasheet specifies GND = 0 V for the electrical characteristics. |
| 5 | INPUT2+ | input | Non-inverting input of comparator 2; the common-mode range is 0 V to VCC-1.5 V and the input can be driven up to +36 V without damage, but should not go below -0.3 V. |
| 6 | INPUT2- | input | Inverting input of comparator 2; the common-mode range is 0 V to VCC-1.5 V and the input can be driven up to +36 V without damage, but should not go below -0.3 V. |
| 7 | OUTPUT2 | output | Open-collector output of comparator 2; the datasheet gives a saturation voltage of 200 mV typical at 4 mA sink and a sink current of 6.0 mA minimum. |
| 8 | VCC | power_in | Positive supply: 2 V to 36 V single supply (absolute maximum 40 V), or ±1.0 V to ±18 V dual supplies. |
