4006 (Variable Length Shift Register - 18 Stage)

Overview

The CD4006 is a versatile 18-stage variable-length shift register from the classic 4000-series CMOS logic family. This integrated circuit provides four independent shift register sections with taps that allow you to configure the total delay length in various combinations, making it ideal for digital delay lines, frequency division, and serial data manipulation. Whether you're a student exploring digital logic, a hobbyist building a custom effect pedal, or an engineer prototyping a timing circuit, the CD4006 offers a simple and reliable solution.

Key Features

• Variable Length Configuration: Four independent shift register sections (4, 4, 4, and 4 stages) with taps at stages 4, 8, 12, and 14, plus a final output at stage 18, allowing flexible delay lengths.
• Wide Operating Voltage: Operates from 3V to 15V, making it compatible with both 5V and 12V systems.
• Low Power Consumption: CMOS technology ensures minimal power draw, ideal for battery-operated projects.
