Description  
• CD74HC161, CD74HCT161 4-Bit Binary Counter,  
Asynchronous Reset  
The Harris CD74HC161, CD74HCT161, CD74HC163 and  
CD74HCT163 are presettable synchronous counters that  
feature look-ahead carry logic for use in high-speed  
counting applications. The CD74HC161 and CD74HCT161  
are asynchronous reset decade and binary counters,  
respectively; the CD74HC163 and CD74HCT163 devices  
decade and binary counters, respectively and are reset  
synchronously with the clock. Counting and parallel  
presetting are both accomplished synchronously with the  
negative-to-positive transition of the clock.

• Wide Operating Temperature Range . . . -55 C to 125 C inputs to be loaded into the counter (provided that the  
setup and hold requirements for SPE are met).  
• Balanced Propagation Delay and Transition Times  
All counters are reset with a low level on the Master Reset  
input, MR. In the CD74HC163 and CD74HCT163 counters  
(synchronous reset types), the requirements for setup and  
hold time with respect to the clock must be met.

- 2V to 6V Operation  
Two count enables, PE and TE, in each counter are  
provided for n-bit cascading. In all counters reset action  
occurs regardless of the level of the SPE, PE and TE inputs  
(and the clock input, CP, in the CD74HC161 and  
CD74HCT161 types).

The look-ahead carry feature simplifies serial cascading of  
the counters. Both count enable inputs (PE and TE) must  
be high to count. The TE input is gated with the Q outputs  
of all four stages so that at the maximum count the terminal  
count (TC) output goes high for one clock period. This TC  
pulse is used to enable the next cascaded stage.
