CE may change only from HIGH-to-LOW while CP
is LOW.
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.

enable (CE) inputs, from the clock enable input (CE) to the clock input (CP) and from the clock input (CP)
to the clock enable input (CE).
(1) HC : VM = 50%; VI = GND to VCC.
