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 incrementing on either the positive-going or negative going transitions.
