DESCRIPTION  
The M74HC190 is an high speed CMOS 4-BIT  
input in multi-stage counters. Control input, Down/  
Up, determines whether a circuit counts up or  
down. A MAX/MIN output and a Ripple Clock  
output provide overflow/underflow indication and  
make possible a variety of methods for generating  
carry/borrow signals in multi-stage counter  
applications.  
All inputs are equipped with protection circuits  
against static discharge and transient excess  
voltage.  
SYNCHRONOUS  
UP/DOWN  
COUNTER  
2
fabricated with silicon gate C MOS technology.  
State changes of the counter are synchronous  
with the LOW-to-HIGH transition of the Clock  
Pulse Input.  
An asynchronous parallel load input overrides  
counting and loads the data present on the DATA  
inputs into the flip-flops, which makes it possible to  
use the circuits as programmable counters. A  
count enable input serves as the carry/borrow
