AC WAVEFORMS

PACKAGE OUTLINES

See

“74HC/HCT/HCU/HCMOS Logic Package Outlines”.

Fig.6

Waveforms showing the clock (CP) to output (Qn) propagation delays, the clock pulse width, 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 data set-up and hold times from the data input (Dn) and from the data enable input

(E) to the clock (CP).

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.
