(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.
Fig.7 Waveforms showing the data input (Dn) to
output (Qn) propagation delays and the
output transition times.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.

Waveforms showing the latch enable input
(LE) pulse width, the latch enable input to
output (Qn) propagation delays and the
output transition times.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.
Fig.9 Waveforms showing the 3-state enable and
disable times.
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.
