DESCRIPTION

The HCC4518B/4520B (extended temperature

range) and HCF4518B/4520B (intermediate tem-

perature range) are monolithic integrated circuits,

available in 16-lead dual in-line plastic or ceramic

package and plastic micro package. The

HCC/HCF4518B Dual BCD Up Counter and

HCC/HCF4520B DualBinary Up Counter each con-

sist of two identical, internally synchronous 4-stage

counters. The counter stages are D-type flip-flops

having interchangeable Clock and Enable lines for

incrementing on either the positive-going or nega-

tive-going transition. For single-unit operation the

Enable input is maintained ”high” and the counter

advances on each positive-going transition of the

Clock. The counters are cleared by high levels on

their Reset lines. The counter can be cascaded in

the ripple mode by connecting Q4 to the enable

input of the subsequent counter while the clockinput

of the latter is held low.
