DESCRIPTION  
The M54/74HC190/191 are high speed CMOS4-BIT  
SYNCHRONOUS UP/DOWN COUNTERS fabri-  
cated in silicon gate C2MOS technology.  
They have the same high speed performance of  
LSTTL combined with true CMOS low power con-  
sumption.  
State changes of the counter are synchronous with  
the LOW-to-HIGH transition of the Clock Pulse input.  
An asynchronous parallel load input overrides count-  
ing and loads the data present on the DATA inputs into  
the flip-flops, which makes it possible to use the cir-  
cuitsasprogrammable counters. Acountenable input  
serves as the carry/borrow input in multi-stage  
counters. Control input, Down/Up, determines  
whether a circuit counts up or down. A MAX/MIN out-  
putand a RippleClockoutput provide overflow/under-  
flow indication and make possible a variety of  
methods for generating carry/borrow signals in multi-  
stage counter applications.  
NC =  
No Internal  
Connection  
Allinputs are equipped with protection circuits against  
static discharge and transient excess voltage.
