IN1

Monitored Input 1. When the voltage at IN1 exceeds its threshold, OUT1 goes

high after the capacitor-adjustable delay period. When the voltage at IN1 falls

below its threshold, OUT1 goes low after a propagation delay.

IN2

Monitored Input 2. When the voltage at IN2 exceeds its threshold, OUT2 goes

high after the capacitor-adjustable delay period. When the voltage at IN2 falls

below its threshold, OUT2 goes low after a propagation delay.

IN3

Monitored Input 3. When the voltage at IN3 exceeds its threshold, OUT3 goes

high after the capacitor-adjustable delay period. When the voltage at IN3 falls

below its threshold, OUT3 goes low after a propagation delay.

IN4

Monitored Input 4. When the voltage at IN4 exceeds its threshold, OUT4 goes

high after the capacitor-adjustable delay period. When the voltage at IN4 falls

below its threshold, OUT4 goes low after a propagation delay.

EN1

Active-High Logic-Enable Input 1. Driving EN1 low causes OUT1 to go low

regardless of the input voltage. Drive EN1 high to enable the monitoring

comparator.

EN2

Active-High Logic-Enable Input 2. Driving EN2 low causes OUT2 to go low

regardless of the input voltage. Drive EN2 high to enable the monitoring

comparator.
