Philips 74HC4520N Dual 4-bit Synchronous Binary Counter DIL16
Manufactured by Philips - 74HC4520N (CD4520) - DIL16 through hole package
GENERAL DESCRIPTION
The 74HC4520 is a high-speed Si-gate CMOS device and is pin compatible with the “4520” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A.
The 74HC4520 is a dual 4-bit internally synchronous binary counter with an active HIGH clock input (nCP0) and an active LOW clock input (nCP1), buffered outputs from all four bit positions (nQ0 to nQ3) and an active HIGH overriding 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 other clock input may be used as a clock enable input. A HIGH on nMR resets the counter (nQ0 to nQ3 = LOW) independent of nCP0 and nCP1.
