Timing Nomenclature
For 3.3 V systems use 1.5 V cross point definitions.
Each timing parameter consists of 5 characters. Some common examples are defined below:
t

t
ELQV
t
GLQV
time (t) from CE
(E) going low (L) to the outputs (Q) becoming valid (V)
time (t) from OE
(G) going low (L) to the outputs (Q) becoming valid (V)
time (t) from address (A) valid (V) to the outputs (Q) becoming valid (V)
t
AVWH
t
WHDX
time (t) from address (A) valid (V) to WE
(W) going high (H)
time (t) from WE
(W) going high (H) to when the data (D) can become undefined (X)

NOTE:
AC test inputs are driven at 3.0 V for a Logic '1'
and 0.0 V for a Logic '0'. Input timing begins
and output timing ends at 1.5 V. Input rise
and fall times (10% to 90%) < 10 ns.
