74HC4520 Datasheet (NXP Semiconductors) - Dual 4-Bit Synchronous Binary Counter

74HC4520, Dual 4-Bit Synchronous Binary Counter

The 74HC4520; 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
