Note 2: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
These products contain MOS elements. Please take care to avoid generating static electricity when handling
these devices.
The oscillation frequency of these devices is determined by the value of the capacitor connected between the
anode and the cathode.
When establishing maximum operating condition parameters, please derate the maximum rating values
specified in these datasheets so as to allow an operational safety margin.
Use of a laminated ceramic capacitor is recommended
Pin 2 and pin 5 should normally be shorted together. If only pin 5 is used, pin 2 should either be left open or
always kept at a lower potential than pin 5. Do not leave pin 5 open and use pin 2 only.
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/Derating Concept and Methods) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
