CLOCK (CL)
The CD4029BMS CLOCK and UP/DOWN inputs are used
directly in most applications. In applications where CLOCK
UP and CLOCK DOWN inputs are provided, conversion to
the CD4029BMS CLOCK and UP/DOWN inputs can easily
be realized by use of the circuit in Figure 11.
CD4029BMS changes count on positive transitions of
CLOCK UP or CLOCK DOWN inputs. For the gate configu-
ration in Figure 12, when counting up the CLOCK DOWN
input must be maintained high and conversely when count-
ing down the CLOCK UP input must be maintained high.
