HEF4518B, Dual BCD counter

The HEF4518B is a dual 4-bit internally synchronous BCD counter.

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

The counter advances on either the LOW to HIGH transition of the CP0 input if CP1 is
