PACKAGE OUTLINES
See
“74HC/HCT/HCU/HCMOS Logic Package Outlines”.
Fig.11 Waveforms showing the set-up and hold times for the input (Dn) and parallel enable input PE.
The shaded areas indicate when the input is permitted to change
for predictable output performance.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.
