(1) HC : V_M = 50%; V_I = GND to V_CC.
HCT : V_M = 1.3 V; V_I = GND to 3 V.
Fig.7 Waveforms showing the input (D_n) to output
(Q_n) propagation delays and the output
transition times.
(1) HC : V_M = 50%; V_I = GND to V_CC.
HCT : V_M = 1.3 V; V_I = GND to 3 V.

Waveforms showing the latch enable input
(LE) pulse width, the latch enable input to
output (Q_n) propagation delays and the
output transition times.
(1) HC : V_M = 50%; V_I = GND to V_CC.
HCT : V_M = 1.3 V; V_I = 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 : V_M = 50%; V_I = GND to V_CC.
HCT : V_M = 1.3 V; V_I = GND to 3 V.
