Note 10: Fairchild’s standard product warranty applies to devices programmed to specifications described herein.
Note 11: V
voltage applied to V
Note 12: 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
may damage the device.
