(1) HC : VM = 50%; VI = GND to VCC.

HCT: VM = 1.3 V; VI = GND to 3 V.

Fig.6 Waveforms showing the data input (nD) to

output (nQ) 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.7 Waveforms showing the data input (nD) to

output (nQ) 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 latch enable input

(LEn-n) pulse width, the latch enable input to

outputs (nQ, nQ) propagation delays and

the output transition 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.
