Notes:
1.
Caution:
The Am28F020 must not be removed from (or inserted into) a socket when V
CC
or V
PP
is applied. If V
CC
鈮?/div>
1.0 Volt,
the voltage difference between V
PP
and V
CC
should not exceed 10.0 Volts. Also, the Am28F020 has a V
PP
rise time and fall
time specification of 500 ns minimum.
2. I
CC1
is tested with OE# = V
IH
to simulate open outputs.
3. Maximum active power usage is the sum of I
CC
and I
PP
.
4. Not 100% tested.
