reset, parallel load, count-up and hold. Four  
control inputs, Master Reset (CLEAR), Parallel  
Enable Input (LOAD), Count Enable Input (PE)  
and Count Enable Carry Input (TE), determine  
the mode of operation as shown in the Truth  
Table. A LOW signal on CLEAR overrides  
counting and parallel loading and sets all outputs  
on LOW state. A LOW signal on LOAD overrides  
counting and allows information on Parallel Data  
Qn inputs to be loaded into the flip-flops on the  
next rising edge of CLOCK. With LOAD and  
CLEAR, PE and TE permit counting when both  
are HIGH. Conversely, a LOW signal on either  
PE and TE inhibits counting.

DESCRIPTION  
The AC161  
is  
a
high-speed CMOS  
SYNCRONOUS PRESETTABLE COUNTER  
fabricated with sub-micron silicon gate and  
double-layer metal wiring C2MOS technology.It is  
ideal for low power applications mantaining high  
speed operation similar to eqivalent Bipolar  
Schottky TTL. It is a 4 bit binary counter with  
AsynchronousClear.  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.  
The circuit have four fundamental modes of  
operation, in order of preference: synchronous
