Notes:
*A 0.01μF capacitor should be placed between V
DD
(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.
