UP/DOWN COUNTER

WITH PRESET

AND RIPPLE CLOCK

The MC74AC190 is a reversible BCD (8421) decade counter which features

synchronous counting and asynchronous presetting. The preset feature allows

the MC74AC190 to be used in programmable dividers. The Count Enable input,

the Terminal Count output and the Ripple Clock output make possible a variety

of methods of implementing multistage counters. In the counting modes, state

changes are initiated by the rising edge of the clock.

• High-Speed — 120 MHz Typical Count Frequency

• Synchronous Counting

• Asynchronous Parallel Load

• Cascadable

• Outputs Source/Sink 24 mA
