(Note 3)

Note 1:
National’s standard product warranty applies to devices programmed to specifications described herein.
Note 2:
V
CC
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 3:
The maximum absolute allowable voltage which may be applied to the V
PP
pin during programming is 14V. Care must be taken when switching the V
PP
supply to prevent any overshoot from exceeding this 14V maximum specification. At least a 0.1
m
F capacitor is required across V
PP
, V
CC
to GND to suppress
spurious voltage transients which may damage the device.
Note 4:
Programming and program verify are tested with the Fast Program Algorithm, at typical power supply voltages and timings.
Note 5:
During power up the PGM pin must be brought high (
t
V
IH
) either coincident with or before power is applied to V
PP
.
