Fig.7
Waveforms showing the minimum pulse width of the latch enable input (LE) and the set-up and hold times
for LE to A

. Set-up and hold times are shown as positive values but may be specified as negative values.
The shaded areas indicate when the input is
permitted to change for predictable output
performance.
