Product specification

74HC/HCT165

The changing to output assumes internal Q6

opposite state from Q7.

(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 (Q7 or Q7) propagation delays, the clock pulse width, the

output transition times and the maximum clock frequency.

The changing to output assumes internal Q6

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

Fig.7 Waveforms showing the parallel load (PL) pulse width, the parallel load to output (Q7 or Q7) propagation

delays, the parallel load to clock (CP) and clock enable (CE) 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 data input (Dn) to output (Q7 or Q7) propagation delays when PL is LOW.
