incrementing on either the positive-going or
negative going transitions. For single-unit
operations 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 clock input of the latter is held low.
DESCRIPTION
HCF4520B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
HCF4520B, a Dual Binary Up Counter, consists of
two identical, internal 4-stage counters. The
counter stages are D-type Flip-Flops having
interchangeable Clock and Enable lines for
