74AC191 Up/Down Counter with Preset and Ripple Clock

November 1988

Revised November 1999

74AC191

Up/Down Counter with Preset and Ripple Clock

General Description

The AC191 is a reversible modulo 16 binary counter. It fea-

tures synchronous counting and asynchronous presetting.

The preset feature allows the AC191 to be used in pro-

grammable 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 ris-

ing edge of the clock.

Features
