1 Inclusive of 25ºC tolerance, operating temperature range, input voltage change, load change, ag-
ing, shock, and vibration. *Excludes Shock/Vibration
2 An internal pullup resistor from pin 1 to pin 4 allows active output if pin 1 is left open.
Note: A 0.01µF capacitor should be placed between Vdd (Pin 4) and GND (Pin2) to minimize
power supply noise.
