NOTES:
1. All currents are in RMS unless otherwise noted. Typical values at V
CC
= 5.0 V, T = +25 °C. These currents are valid for all
product versions (packages and speeds).
2. I
CCES
is specified with the device deselected. If the device is read while in erase suspend mode, current draw is the sum of
I
CCES
and I
CCR
.
3. Block erases and word/byte program operations are inhibited when V
PP
= V
PPLK
, and not guaranteed in the range between
V
PPH
1 and V
PPLK
.
4. Sampled, not 100% tested.
5. Automatic Power Savings (APS) reduces I
CCR
to less than 1 mA typical, in static operation.
6. CMOS Inputs are either V
CC
± 0.2 V or GND ± 0.2 V. TTL Inputs are either V
IL
or V
IH
.

NOTE:
AC test inputs are driven at 3.0 V for a logic “1” and 0.0 V for a logic “0.” Input timing begins, and output timing ends, at 1.5 V.
Input rise and fall times (10% to 90%) <10 ns.
