MM54HC192/MM74HC192  
Synchronous Decade Up/Down Counters  
MM54HC193/MM74HC193  
Synchronous Binary Up/Down Counters  
General Description  
These high speed synchronous counters utilize advanced  
silicon-gate CMOS technology to achieve the high noise im-  
munity and low power consumption of CMOS technology,  
along with the speeds of low power Schottky TTL. The  
MM54HC192/MM74HC192 is a decade counter, and the  
MM54HC193/MM74HC193 is a binary counter. Both coun-  
ters have two separate clock inputs, an UP COUNT input  
and a DOWN COUNT input. All outputs of the flip-flops are  
simultaneously triggered on the low to high transition of ei-  
ther clock while the other input is held high. The direction of  
counting is determined by which input is clocked.  
Both a BORROW and CARRY output are provided to en-  
able 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 counter overflows. The counters can be cascaded by  
connecting the CARRY and BORROW outputs of one de-  
vice to the COUNT UP and COUNT DOWN inputs, respec-  
tively, of the next device.  
All inputs are protected from damage due to static dis-  
charge by diodes to V  
and ground.  
CC  
These counters may be preset by entering the desired data  
on the DATA A, DATA B, DATA C, and DATA D inputs.  
When the LOAD input is taken low the data is loaded inde-  
pendently of either clock input. This feature allows the count-  
ers to be used as divide-by-n counters by modifying the  
count length with the preset inputs.

Typical operating frequency: 27 MHz  
Wide power supply range: 2–6V  
Low quiescent supply current: 80 mA maximum  
(74HC Series)  
In addition both counters can also be cleared. This is ac-  
complished by inputting a high on the CLEAR input. All 4  
internal stages are set to a low level independently of either  
COUNT input.
