Product speciï¬cation
74HC/HCT377
(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, output
transition times and the maximum clock pulse frequency.
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.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).
