Product Overview

National Semiconductor CD4066BCN is a CMOS quad bilateral switch designed for controlled routing of analog or digital signals. Each of the four independent switches operates bidirectionally, allowing signals to pass in either direction when enabled by a logic control input.

Built on the CD4000-series CMOS platform, the CD4066BCN operates over a wide supply range and offers low quiescent current, making it suitable for battery-powered systems as well as industrial control designs. The DIP-14 through-hole package supports legacy boards and prototyping environments that require a classic footprint.

Key Features

• DIP-14 through-hole package
• Manufactured by National Semiconductor

Applications

• Analog signal multiplexing
• Audio signal switching
• Sample-and-hold circuits
• Sensor signal selection
• Battery-powered control systems
• Industrial control and automation boards
• Repair of legacy equipment specifying CD4066BCN

Frequently Asked Questions

Can this switch both analog and digital signals?

Yes. The CD4066BCN is designed to pass either analog waveforms or digital logic signals within the supply voltage range.

Are the switches independent?

Yes. All four bilateral switches are independently controlled by separate logic inputs.

Is this compatible with other 4066 variants?

It is generally pin-compatible with other CD4066 devices, but electrical characteristics should be verified against your circuit requirements.

What package does this use?

This version is supplied in a 14-pin DIP through-hole package suitable for socketed or direct PCB mounting.

Four analog gates in one classic DIP package. If your design calls for a CD4066BCN, this National Semiconductor part keeps signal routing simple and period-correct.
