U74HC4060

DESCRIPTION 

The U74HC4060 are high-speed Si-gate CMOS device. 

The U74HC4060 devices consist of an oscillator section and 

14 ripple-carry binary counter stages. The oscillator configuration 

allows design of erther RC or crystal oscillator circuits with three 

oscillator terminals (CLKI, CLKO, CLKO) , ten buffered outputs 

(QD to QJ and QL to QM) and an overriding asynchronous master 

reset (CLR) . The oscillator may be replaced by an esternal clock 

signal at input CLKI. In this case keep the other oscillator pins 

(CLKO, CLKO) floating. The counter advances on the 

negative-going transition of CLKI. A high level at the clear (CLR) 

input disables the oscillator and resets the counter to zero (all Q 

output low). 

FEATURES
