Timing Nomenclature

All 3.3 V systems are measured from where signals cross 1.5 V. For 5.0 V systems use the standard JEDEC cross

point definitions. Each timing parameter consists of 5 characters. Some common examples are defined below:

tCE tELQV time (t) from CE » (E) going low (L) to the outputs (Q) becoming valid (V)

tOE tGLQV time (t) from OE » (G) going low (L) to the outputs (Q) becoming valid (V)

tACC tAVQV time (t) from address (A) valid (V) to the outputs (Q) becoming valid (V)

tAS tAVWH time (t) from address (A) valid (V) to WE » (W) going high (H)

tDH tWHDX time (t) from WE » (W) going high (H) to when the data (D) can become undefined (X)
