Key Features
- 4 independent bidirectional SPST analog switches in a single 14-pin DIP package for versatile signal routing without external logic components
- Wide 2 V to 6 V supply range with low on-resistance and HC-family CMOS control inputs compatible with 3.3 V and 5 V logic systems
- Bidirectional signal flow on each channel allows both analog and digital signals up to the supply voltage to be switched with minimal distortion
Applications
The CD74HC4066EG4 is used to route analog audio signals, sensor outputs, and digital data lines in applications where multiple signal paths must be independently enabled or disabled under microcontroller control. Four independent SPST channels in a 14-pin DIP package make it a popular choice for signal multiplexing in prototyping boards, audio mixer circuits, and data acquisition systems requiring manual or digital switching. The through-hole DIP format simplifies breadboard prototyping and field-service replacement in industrial control equipment.

Frequently Asked Questions
How many analog switch channels does the CD74HC4066EG4 provide and what supply voltage does it require?
The CD74HC4066EG4 contains 4 independent SPST bidirectional analog switch channels operating from a 2 V to 6 V supply, enabling it to switch both analog and digital signals under CMOS logic control in 3.3 V and 5 V system designs.
Can the CD74HC4066EG4 switch audio frequency signals without significant attenuation or distortion?
Yes, the CD74HC4066EG4 has low on-resistance and flat frequency response across the audio band (20 Hz to 20 kHz), making it suitable for switching stereo audio lines, microphone signals, and audio multiplexing in consumer electronics and mixing board circuits with minimal signal degradation.
How does the CD74HC4066EG4 compare to the CD4066B it replaces in a 5 V logic design?
The CD74HC4066EG4 is the HC-speed CMOS successor to the CD4066B, offering faster switch turn-on and turn-off times and lower on-resistance while maintaining pin-for-pin compatibility in the 14-pin DIP footprint; in 5 V designs this results in reduced charge injection and improved switching speed for higher-frequency analog signal routing.
What package does the CD74HC4066EG4 use and what are the trade-offs versus the SOIC variant for production PCBs?
The CD74HC4066EG4 uses a 14-pin DIP package with 2.54 mm pin pitch, which is ideal for breadboard prototyping and hand-soldered through-hole assembly but occupies roughly 3 times the PCB area of the equivalent SOIC-14 package; production designs with space constraints typically migrate to the SOIC or TSSOP surface-mount variants.
