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 0.01F capacitor should be placed between Vdd (Pin 4) and GND (Pin2) to minimize
power supply noise.
*Dimensional drawing is for reference to critical specifications defined by size measurements.
Certain non-critical visual attributes, such as side castellations, reference pin shape, etc. may
vary. All specifications subject to change without notice.
