Note 1:
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of
the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
Note 2:
This parameter is only sampled and is not 100% tested.
Note 3:
OE may be delayed up to t
ACC
- t
OE
after the falling edge of CE without impacting t
ACC
.
Note 4:
The t
DF
and t
CF
compare level is determined as follows:
High to TRI-STATE
®
, the measured V
OH1
(DC) - 0.10V;
Low to TRI-STATE, the measured V
OL1
(DC) + 0.10V.
Note 5:
TRI-STATE may be attained using OE or CE .
Note 6:
The power switching characteristics of EPROMs require careful device decoupling. It is recommended that at least a 0.1
µF
ceramic capacitor be used on every device
between V
CC
and GND.
Note 7:
The outputs must be restricted to V
CC
+ 1.0V to avoid latch-up and device damage.
Note 8:
1 TTL Gate: I
OL
= 1.6 mA, I
OH
= -400

C

Note 9:

may be connected to V

except during programming.
Note 10:
Inputs and outputs can undershoot to -2.0V for 20 ns Max.

Note 11:
Fairchild’s standard product warranty applies only to devices programmed to specifications described herein.
Note 12:
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 13:
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
µF
capacitor is required across V
PP
, V
CC
to GND to suppress spurious voltage transients
which may damage the device.
Note 14:
During power up the CE/PGM pin must be brought high (≥V
IH
) either coincident with or before power is applied to V
