 软件简介 |
The CD4017BC is a 5-stage divide-by-10 Johnson counter
with 10 decoded outputs and a carry out bit.
The CD4022BC is a 4-stage divide-by-8 Johnson counter
with 8 decoded outputs and a carry-out bit.
These counters are cleared to their zero count by a logical
“1” on their reset line. These counters are advanced on the
positive edge of the clock signal when the clock enable signal
is in the logical “0” state.
The configuration of the CD4017BC and CD4022BC permits
medium speed operation and assures a hazard free
counting sequence. The 10/8 decoded outputs are normally
in the logical “0” state and go to the logical “1” state
only at their respective time slot. Each decoded output
remains high for 1 full clock cycle. The carry-out signal
completes a full cycle for every 10/8 clock input cycles and
is used as a ripple carry signal to any succeeding stages.
