54AC191

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 program-

mable 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.

Features

n ICC reduced by 50%

n High speed — 133 MHz typical count frequency

n Synchronous counting

n Asynchronous parallel load

n Cascadable

n Outputs source/sink 24 mA

n Standard Military Drawing (SMD)
