HEF4520B Overview
The HEF4520B is a dual 4-bit internally synchronous binary counter with two clock inputs (nCP0 and nCP1), buffered outputs from all four bit positions (nQ0 to nQ3) and an asynchronous master reset input (nMR). The counter advances on either the LOW-to-HIGH transition of nCP0 if nCP1 is HIGH or the HIGH-to-LOW transition of nCP1 if nCP0 is LOW. Either nCP0 or nCP1 may be used as the clock input to the counter and the...
