DC CHARACTERISTICS
TTL/NMOS Compatible
CMOS Compatible
Notes for DC Characteristics (both tables):
1. The I
CC
current listed includes both the DC operating current and the frequency dependent component (at 6 MHz).
The frequency component typically is less than 2 mA/MHz, with OE# at V
IH
.
2. Maximum I
CC
specifications are tested with V
CC
= V
CCmax
.
3. I
CC
active while Embedded Algorithm (program or erase) is in progress.
4. Not 100% tested.
5. For CMOS mode only, I
CC3
= 20 μA max at extended temperatures (> +85°C).
