Programming Characteristics
Note 11: Fairchild’s standard product warranty applies only to devices programmed to specifications described herein.
Note 12: V
voltage applied to V
Note 13: The maximum absolute allowable voltage which may be applied to the V
prevent any overshoot from exceeding this 14V maximum specification. At least a 0.1 F capacitor is required across V
which may damage the device.
Note 14: During power up the CE/PGM pin must be brought high ( V
