Typical Application Circuits

Precautions during Use

(1)

TA76432FT, TA76432FC, TA76432F/FR, TA76432S

These products contain MOS elements. Please take care to avoid generating static electricity when

handling these devices.

(2)

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.

(3)

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.
