HD74HC390 Product details

Description

The HD74HC390 incorporate dual decade counters, each composed of a divide-by-two and a divide-byfive counter.

The divide-by-two and divide-by-five counters can be cascaded to form dual decade, dual biquinary, or various combinations up to a single divide-by-100 counter.
