Octal D-type transparent latch; 3-state

74HC/HCT373

AC WAVEFORMS

Fig.7

Waveforms showing the 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.

Fig.8

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.

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

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

Fig.10 Waveforms showing the data set-up and hold times for Dn input to LE input.

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.
