An internal pullup resistor from pin 1 to pin 4 allows active output if pin 1 is left open.

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 are subject to change without notice
