General Description

The HEF4520B is a dual 4-bit internally synchronous binary counter.

The counter has an active HIGH clock input (CP0) and an active LOW clock input (CP1), buffered outputs from all four bit positions (O0 to O3) and an active HIGH overriding asynchronous master reset input (MR).

The counter advances on either the LOW to HIGH transition of the CP0 input if CP1 is HIGH or the HIGH to HEF4520B MSI LOW transition of the CP1 input if CP0 is low.
