DESCRIPTION  
The M74HC192 is an high speed CMOS  
the counter can also be cleared. This is  
accomplished by inputting a high on the CLEAR  
input. All 4 internal stages are set to low  
independently of either COUNT input. Both a  
BORROW and CARRY output are provided to  
enable cascading of both up and down counting  
functions. The BORROW output produces a  
negative going pulse when the counter underflows  
and the CARRY outputs a pulse when the  
counters overflows. The counter can be cascaded  
by connection the CARRY and BORROW outputs  
of one device to the COUNT UP and COUNT  
DOWN inputs, respectively, of the next device.  
All inputs are equipped with protection circuits  
against static discharge and transient excess  
voltage.  
SYNCRONOUS  
COUNTERS fabricated with silicon gate C MOS  
technology.  
UP/DOWN  
DECADE  
2
The counter has two separate clock inputs, an UP  
COUNT input and a DOWN COUNT input. All  
outputs of the flip-flop are simultaneously  
triggered on the low to high transition of either  
clock while the other input is held high. The  
direction of counting is determined by which input  
is clocked. This counter may be preset by entering  
the desired data on the DATA A, DATA B, DATA  
C, and DATA D input. When the LOAD input is  
taken low the data is loaded independently of  
either clock input. This feature allows the counters  
to be used as divide-by-n counters by modifying  
the count length with the preset inputs. In addition
