74HCT4520 Description
74HCT4520 are dual 4-bit internally synchronous binary counters with two clock inputs (nCP0 and nCP1). They have buffered outputs from all 4 bit positions (nQ0 to nQ3) and an asynchronous master reset input (nMR). The counter advances on the LOW-to-HIGH transition of nCP0 when nCP1 is HIGH.
