HEF4520B-Q100 Datasheet Dual Binary Counter

Manufacturer: Nexperia

Overview: HEF4520B-Q100 Dual binary counter Rev. 1 — 14 March 2017 Product data sheet 1.

General Description

The HEF4520B-Q100 is a dual 4-bit internally synchronous binary counter.

The counter has 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 the nCP0 input if nCP1 is HIGH or the HIGH-to-LOW transition of the nCP1 input if nCP0 is LOW.
