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