DESCRIPTION

HCF4518B is a monolithic integrated circuit

fabricated in Metal Oxide Semiconductor

technology available in DIP and SOP packages.

HCF4518B Dual BCD 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

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.
