Part (a) of AC Test Loads was used for all parameters except t
, t
, t
and t
, which use part (b).
The parameters t
and t
are measured as the delay from the input disable logic threshold transition to V
- 0.5 V for an enabled HIGH output or V
OL
+0.5V for an enabled LOW output. Please see part (c) of AC Test Loads and Waveforms for waveforms and measurement reference levels.
