(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.
Fig.7
Waveforms showing the clock (CP) to
output (Qn) and terminal count (TC)
propagation delays, the clock pulse width
and the maximum clock pulse frequency.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.
Fig.8
Waveforms showing the set-up and hold
times form count enable (CE) and up/down
(UP/DN) control inputs to the clock pulse
(CP), the propagation delays from UP/DN,
CE to TC.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.
Fig.9 Waveforms showing the preset enable
pulse width, preset enable to output
delays and output transition times.
(1) HC : VM = 50%; VI = GND to VCC.
HCT: VM = 1.3 V; VI = GND to 3 V.
Fig.10 Waveforms showing the master reset pulse,
master reset to terminal count and Qn
delay and master reset to clock removal
time.
