Notes:
1. V
CC
must be applied simultaneously or before V
PP
, and removed simultaneously or after V
PP
.
2. This parameter is only sampled and not 100% tested.
3.
Caution:
The Am27C256 must not be removed from (or inserted into) a socket or board when V
PP
or V
CC
is applied.
4. For the -55 and -70:
Output Load: 1 TTL gate and C
L
= 30 pF
Input Rise and Fall Times: 20 ns
Input Pulse Levels: 0 V to 3 V
Timing Measurement Reference Level: 1.5 V for inputs and outputs
For all other versions:
Output Load: 1 TTL gate and C
L
= 100 pF
Input Rise and Fall Times: 20 ns
Input Pulse Levels: 0.45 V to 2.4 V
Timing Measurement Reference Level: 0.8 V and 2 V inputs and outputs
Chip Enable HIGH or
