High-Speed CMOS Logic  
Presettable Synchronous 4-Bit Up/Down Counters  
September 1997 - Revised October 2003  
Presetting the counter to the number on the preset data inputs  
(P0-P3) is accomplished by a LOW asynchronous parallel  
Features  
• Synchronous Counting and Asynchronous  
Loading  
load input (PL). The counter is incremented on the low-to-high  
transition of the Clock-Up input (and a high level on the Clock-  
Down input) and decremented on the low to high transition of  
the Clock-Down input (and a high level on the Clock-up input).  
A high level on the MR input overrides any other input to clear  
the counter to its zero state. The Terminal Count up (carry)  
goes low half a clock period before the zero count is reached  
and returns to a high level at the zero count. The Terminal  
Count Down (borrow) in the count down mode likewise goes  
low half a clock period before the maximum count (9 in the  
192 and 15 in the 193) and returns to high at the maximum  
count. Cascading is effected by connecting the carry and  
borrow outputs of a less significant counter to the Clock-Up  
and Clock-Down inputs, respectively, of the next most  
significant counter.
