(1) In order to realize low-power operation, the device has a high impedance; the shaded portion in the figure below is highly susceptible to
(2) Power supply filter capacitor
(3) This device passes a drop test (from 75 cm onto a hard board), but it is possible for the crystal resonator to be damaged by the shocks
(4) There is a possibility of damage to the crystal resonator during ultrasonic cleaning. Because of the wide variation of conditions in ultrasonic
(5) This is a CMOS device, and the standard precautions against static electricity should be taken.
Note:
inductance effects, and should be kept clear of signal lines.
To ensure stable operation against transients and noise, connect a bypass capacitor of at least 0.01 F (ceramic) across the power supply,
close to the device.
