TA76L431FT, TA76L431S These products contain MOS elements. Please take care to avoid generating static electricity when handling these devices. 2. TA76L431FT, TA76L431S 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 absolute 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 TA76L431FT 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.

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). 3 2011-10-11 TA76L431FT/S Operating Ranges Characteristics Symbol Min Typ.
