Synchronous Presettable Binary Counter
General Description
The AC/ACT161 are high-speed synchronous modulo-16
binary counters. They are synchronously presettable for
application in programmable dividers and have two types
of Count Enable inputs plus a Terminal Count output for
versatility in forming synchronous multistage counters. The
AC/ACT161 has an asynchronous Master Reset input that
overrides all other inputs and forces the outputs LOW.
Features
s ICC reduced by 50%
s Synchronous counting and loading
s High-speed synchronous expansion
s Typical count rate of 125 MHz
s Outputs source/sink 24 mA
s ACT161 has TTL-compatible inputs

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, with-
out exception, to ensure that the system design is reliable over its power
supply, temperature, and output/input loading variables. Fairchild does not
recommend operation of FACT circuits outside databook specifications.
