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.
