Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Comparator 1 open-collector output (NPN transistor with grounded emitter), sink current limited to about 16mA, load may connect to any supply within the allowed range. |
| 2 | IN1- | input | Comparator 1 inverting input; input common-mode range extends to ground, and input must not go below -0.3V. |
| 3 | IN1+ | input | Comparator 1 non-inverting input; input common-mode range extends to ground, and input must not go below -0.3V. |
| 4 | GND | power_in | Ground; unused comparator pins must be connected to ground. |
| 5 | IN2+ | input | Comparator 2 non-inverting input; input common-mode range extends to ground, and input must not go below -0.3V. |
| 6 | IN2- | input | Comparator 2 inverting input; input common-mode range extends to ground, and input must not go below -0.3V. |
| 7 | OUT B | output | Comparator 2 open-collector output (NPN transistor with grounded emitter), sink current limited to about 16mA, load may connect to any supply within the allowed range. |
| 8 | Vcc | power_in | Positive supply, 2.0V to 36V single supply (or ±1.0V to ±18V dual supply), with absolute maximum 36V. |
