Note 10:
Fairchild
’
s standard product warranty applies to devices programmed to specifications described herein.
Note 11:
V
must be applied simultaneously or before V
PP
and removed simultaneously or after V
PP
. The EPROM must not be inserted into or removed from a board with
voltage applied to V
PP
or V
CC
.
Note 12:
The maximum absolute allowable voltage which may be applied to the V
pin during programming is 14V. Care must be taken when switching the V
supply to
prevent any overshoot from exceeding this 14V maximum specification. At least a 0.1
μ
F capacitor is required across V
CC
to GND to suppress spurious voltage transients which
may damage the device.
