Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT2 | output | Open-collector output of comparator 2; unused outputs must be left open. |
| 2 | OUT1 | output | Open-collector output of comparator 1; unused outputs must be left open. |
| 3 | VCC | power_in | Positive supply; 5.0 to 30 V single supply (±2.5 to ±15 V split), 36 V (±18 V) absolute maximum. |
| 4 | IN1(-) | input | Inverting input of comparator 1; keep within GND to VCC and tie unused inputs to GND or VCC. |
| 5 | IN1(+) | input | Non-inverting input of comparator 1; keep within GND to VCC and tie unused inputs to GND or VCC. |
| 6 | IN2(-) | input | Inverting input of comparator 2; keep within GND to VCC and tie unused inputs to GND or VCC. |
| 7 | IN2(+) | input | Non-inverting input of comparator 2; keep within GND to VCC and tie unused inputs to GND or VCC. |
| 8 | IN3(-) | input | Inverting input of comparator 3; keep within GND to VCC and tie unused inputs to GND or VCC. |
| 9 | IN3(+) | input | Non-inverting input of comparator 3; keep within GND to VCC and tie unused inputs to GND or VCC. |
| 10 | IN4(-) | input | Inverting input of comparator 4; keep within GND to VCC and tie unused inputs to GND or VCC. |
| 11 | IN4(+) | input | Non-inverting input of comparator 4; keep within GND to VCC and tie unused inputs to GND or VCC. |
| 12 | GND | power_in | Ground (negative supply for split-supply operation). |
| 13 | OUT4 | output | Open-collector output of comparator 4; unused outputs must be left open. |
| 14 | OUT3 | output | Open-collector output of comparator 3; unused outputs must be left open. |
