Output
AC Testing (all speed options except -70): Inputs are driven at
2.4 V for a logic “1” and 0.45 V for a logic “0”. Input pulse rise
and fall times are ≤10 ns.
AC Testing for -70 devices: Inputs are driven at 3.0 V for a
logic “1” and 0 V for a logic “0”. Input pulse rise and fall times
are ≤10 ns.
