Programming Waveforms
Note 11: Fairchild’s standard product warranty applies 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: Programming and program verify are tested with the interactive Program Algorithm, at typical power supply voltages and timings.
