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.8 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.
