AC WAVEFORMS

Product specification

74HC/HCT173

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

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

Fig.6

Waveforms showing the clock (CP) to

output (Qn) propagation delays, the clock

pulse width, the output transition times and

the maximum clock pulse frequency.

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

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

Fig.7

Waveforms showing the master reset (MR)

pulse width, the master reset to output (Qn)

propagation delays and the master reset to

clock (CP) removal time.

(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.

Fig.9 Waveforms showing the data set-up and hold

times from input (En, Dn) to clock (CP).
