Note
t
SKEW
indicates the following three types of time depending on the condition.
1) When switching /CE from high level to low level, t
SKEW
is the time from the /CE low level input point until the
next address is determined.
2) When switching /CE from low level to high level, t
SKEW
is the time from the address change start point to the
/CE high level input point.
3) When /CE is fixed to low level, t
SKEW
is the time from the address change start point until the next address is
determined.
Since specs are defined for t
SKEW
only when /CE is active, t
SKEW
is not subject to limitations when /CE is
switched from high level to low level following address determination, or when the address is changed after
/CE is switched from low level to high level.
Remark
t
DF
is the time from inactivation of Chip Enable input (/CE) or Output Enable input (/OE or OE) to
high impedance state output.
