Notes: 1. AC measurements assume that t
T
= 1 ns.
2. The reference level for timing of input signals is 1.4 V.
The input signal conditions are below.
V
IH
= 2.4 V, V
IL
= 0.4 V
3. Output load.
Z = 50Ω
Output
50 pF (External Load)
4. The access time is defined at 1.4 V.
5. If t
T
is longer than 1 ns, then the reference level for timing of input signals is V
IH
and V
IL
.
