Product specification

74HC/HCT4015

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

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

Fig.6 Waveforms showing the clock (nCP) to output (nQn) propagation delays, the clock pulse width, the output

transition times and the maximum clock 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 (nMR) pulse width, the master reset to output (nQn) propagation

delay and the master reset to clock (nCP) removal time.

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.
