These products contain MOS elements. Please take care to avoid generating static electricity when
handling these devices.
TA76432FT, TA76432FC, TA76432F/FR, TA76432S
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 TA76432FT/TA76432FC
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.
