FACT DATA
The MC74AC160/74ACT160 and MC74AC162/74ACT162 are high-speed
synchronous decade counters operating in the BCD (8421) sequence. 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 MC74AC160/74ACT160 has an
asynchronous Master Reset input that overrides all other inputs and forces the
outputs LOW. The MC74AC162/74ACT162 has a Synchronous Reset input that
overrides counting and parallel loading and allows all outputs to be simultaneously
reset on the rising edge of the clock.
Synchronous Counting and Loading
High-Speed Synchronous Expansion
Typical Count Rate of 120 MHz
Outputs Source/Sink 24 mA
