¹Inclusive of 25ºC tolerance, operating temperature range, input voltage change, load change, ag-

ing, shock, and vibration. *Excludes Shock/Vibration

²An internal pullup resistor from pin 1 to pin 4 allows active output if pin 1 is left open.

Note: A 0.01µF bypass capacitor should be placed between VDD (Pin 4) and GND (Pin 2) to

minimize power supply line noise.
