Product Introduction

Overview

The MC74HC390ADR2G, produced by Onsemi, is a dual 4-stage binary ripple counter integrated circuit. It is part of the 74HC series and is known for its high-performance silicon-gate CMOS technology. This device is identical in pinout to the LS390 and consists of two independent 4-bit counters, each composed of a divide-by-two and a divide-by-five section. The counters have separate clock inputs and can be cascaded to implement various combinations of divide-by-2 and/or divide-by-5 up to a divide-by-100 counter. The device is compatible with standard CMOS outputs and, with pullup resistors, can also be compatible with LSTTL outputs.
