1 Inclusive of 25ºC tolerance, operating temperature range, input voltage change, load change, shock,
and 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. All specifications subject to change without notice.
All dimensions are in millimeters.
