TA76432AFT, TA76432AF/AFR, TA76432AS
These products contain MOS elements. Please take care to avoid generating static electricity when
handling these devices.
TA76432AFT, TA76432AF/AFR, TA76432AS
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.
Precautions when handling anode pin of TA76432AFT
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).
