54F/74F190

Up/Down Decade Counter with Preset and Ripple Clock

General Description

Features

High-speedÐ125 MHz typical count frequency

The ’F190 is a reversible BCD (8421) decade counter fea-

turing synchronous counting and asynchronous presetting.

The preset feature allows the ’F190 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.
