AC WAVEFORMS

Product specification

74HC/HCT4017

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

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

Fig.7 Waveforms showing the hold and set-up times for CP0 to CP1 and CP1 to CP0.

Conditions:

CP1 = LOW while CP0 is triggered on a LOW-to-HIGH

transition and CP0 = HIGH, while CP1 is triggered on a

HIGH-to-LOW transition.

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

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

Fig.8 Waveforms showing the minimum pulse widths for CP0, CP1 and MR inputs; the recovery time for MR and

the propagation delays for MR to Qn and Q5-9 outputs.
