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.

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.
