Assumes that t
RCD
<=t
RCD
(max) and t
RAD
<=t
RAD
(max). If t
RCD
or t
RAD
is greater than the maximum
recommended value shown in this table, t
RAC
exceeds the value shown.
Measured with a load circuit equivalent to 2TTL loads and 100

<=t

>=t
RAD
(max).
t
OFF
(max) defines the time at which the output achieves the open circuit condition and is not
referenced to output voltage levels.
V
IH
(min) and V
IL
(max) are reference levels for measuring timing of input signals. Also,
transition times are measured between V
IH
and V
IL
.
Operation with the t
RCD
(max) limit insures that t
RAC
(max) can be met, t
RCD
(max) is specified as a
reference point only; if t
RCD
is greater than the specified t
RCD
(max) limit, then access time is
controlled exclusively by t
CAC
.
Operation with the t
RAD
(max) limit insures that t
RAC
(max) can be met, t
RAD
(max) is specified as a
reference point only; if t
RAD
is greater than the specified t
RAD
(max) limit, then access time is
controlled exclusively by t
AA
