An internal pull-up resistor from pin 1 to pin 4 allows active output if pin 1 is left open. Notes: *A 0.01μF capacitor should be placed between VDD (Pin 4) and GND (Pin2) to minimize power supply line 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.
