AC CHARACTERISTICS
Caution:
Do not remove the device from (or insert it into) a socket or board that has V
PP
or V
CC
applied.
Notes:
1. V
CC
must be applied simultaneously or before V
PP
, and removed simultaneously or after V
PP
.
2. This parameter is sampled and not 100% tested.
3. Switching characteristics are over operating range, unless otherwise specified.
4. See Figure 3 and Table 1 for test specifications.
SWITCHING WAVEFORMS
Notes:
1. OE# may be delayed up to t
ACC
– t
OE
after the falling edge of the addresses without impact on t
ACC
.
2. t
DF
is specified from OE# or ‘CE#, whichever occurs first.
PACKAGE CAPACITANCE
Notes:
1. This parameter is only sampled and not 100% tested.
2. T
