SPECIFICATIONS
`
Note:
1, A 0.01μF capacitor should be placed between VDD
(Pin 4) and GND (Pin2) to minimize power supply line
noise.
2, Dimensional drawing is for reference to critical
specifications defined by size measurements. Certain
non-critical visual attributes, such as side castellation’s,
etc. may vary.
