HEF4520B  
Dual binary counter  
Rev. 6 — 18 November 2011  
Product data sheet  
1. General description  
The HEF4520B 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. Either nCP0 or  
nCP1 may be used as the clock input to the counter while the other clock input may be  
used as a clock enable input. Schmitt trigger action makes the clock input highly tolerant  
of slower clock rise and fall times. A HIGH on nMR resets the counter (nQ0 to  
nQ3 = LOW) independent of nCP0 and nCP1.  
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS  
(usually ground). Unused inputs must be connected to VDD, VSS, or another input.  
2. Features and benefits
