AC WAVEFORMS
(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.
