1. If the combinatorial input changes while LE is in the latched mode and LE goes into the transparent mode after tPTD ns has
elapsed, the corresponding latched output will change tGOL ns after LE goes into the transparent mode. If the combinatorial
input change while LE is in the latched mode and LE goes into the transparent mode before tPTD ns has elapsed, the corre-
sponding latched output will change at the later of the following—tPTD ns after the combinatorial input changes or tGOL ns after
LE goes into the latched mode.
