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.

NOTE:
AC test inputs are driven at VOH (2.4 VTTL) for a logic “1” and VOL (0.45 VTTL) for a logic “0.” Input timing begins at VIH (2.0 VTTL
and VIL (0.8 VTTL) . Output timing ends at VIH and VIL. Input rise and fall times (10% to 90%) <10 ns.
