HEF4520B  
Dual binary counter  
Rev. 8 — 1 March 2022  
Product data sheet  
1. General description  
The HEF4520B is a dual 4-bit internally synchronous binary counter with two clock inputs (nCP0  
and nCP1), buffered outputs from all four bit positions (nQ0 to nQ3) and an 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.  
Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to  
voltages in excess of VDD  
.
2. Features and benefits  
Tolerant of slow clock rise and fall times  
Fully static operation  
5 V, 10 V, and 15 V parametric ratings  
Wide supply voltage range from 3.0 V to 15.0 V  
CMOS low power dissipation  
High noise immunity  
Standardized symmetrical output characteristics  
Complies with JEDEC standard JESD 13-B  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115-B exceeds 200 V  
Specified from -40 °C to +85 °C
