Dual 4-bit synchronous binary counter

1. General description The 74HC4520-Q100; 74HCT4520-Q100 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 either t
