74F190

Up/Down Decade Counter with Preset and Ripple Clock

General Description

Features

The 74F190 is a reversible BCD (8421) decade counter

featuring synchronous counting and asynchronous preset-

ting. The preset feature allows the 74F190 to be used in

programmable dividers. The Count Enable input, the Termi-

nal Count output and the Ripple Clock output make possi-

■ High-speed—125 MHz typical count frequency

■ Synchronous counting

■ Asynchronous parallel load

■ Cascadable

ble

a variety of methods of implementing multistage

counters. In the counting modes, state changes are initi-

ated by the rising edge of the clock.
