1 Inclusive of 25ºC tolerance, operating temperature range, input voltage change, load change,
reflow and one year aging.
2 An 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.
All dimensions are in millimeters.
