5. NOTES
1. HANDLING
(ELECTROSTATIC DISCHARGES)
This device is made with CMOS circuitry. Please take precautions
to prevent damage due to electrical static discharge.
(SHOCK RELIABILITY)
This device contains a quartz crystal, so please do not give too much shock or vibration.
An automatic insersion is available, however, the internal quartz crystal might be damaged in
case that too much shock or vibration is given by machine condition. Be sure to check your
machine condition in advance.
(CLEANING)
Since, depending on the cleaning conditions,there is a possibility of damage being caused to
the Crystal Osillator,do not fail to test and confirm the results beforehand,using your
company's cleaning conditions.
(TEMPERATURE AND HUMIDITY)
We recommend to store and use device under normal temperature and humidity.
When this device is used in high humidity applications, there is a potential problem with
condensation.
As with other IC's, please take precautions to prevent condensation.
2. CIRCUIT DESIGNS
(POWER LINES)
We recommend placing a 0.01 ~ 0.1µF capacitor between VDD and GND to obtain stable
operation and protect against power line ripple .
VDD and GND pattern should be as wide as possible.
(OE INPUT LINE)
When OE pin is not used, please connect it to VDD.
(OUTPUT LINE)
As a long output line may cause irregular output, please take care to design that output line is
as short as possible, and also keep high level signal source away from this device.
