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

and vibration.

²An 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.
