- Four independent channels (1:1 SPST) with normally-open configuration for versatile multiplexing and signal gating
- Supports negative supply voltage down to -5 V for dual-supply analog switching in mixed-signal circuit designs
- 14-pin SOP package (JEDEC R-PDSO-G14) with RoHS e4 compliance for compact surface-mount assembly
Applications
The CD4066BNSR is widely used in analog signal multiplexing, audio switching, and communication interface selection circuits where multiple signal paths must be independently controlled by digital logic. Its quad bilateral switch architecture makes it ideal for sample-and-hold circuits, signal attenuation networks, and chopper-stabilized amplifier designs. The wide supply range and 40 MHz bandwidth enable deployment in both low-frequency audio and high-frequency data acquisition applications.

Frequently Asked Questions
What is the bandwidth of the CD4066BNSR?
The CD4066BNSR has a nominal bandwidth of 40 MHz, making it suitable for both analog audio signal switching and moderate-frequency digital signal routing applications. This bandwidth allows the switch to handle a wide range of signals without significant distortion or attenuation.
How many switch channels does the CD4066BNSR have?
The CD4066BNSR contains four independent SPST (Single-Pole Single-Throw) bilateral switch channels. Each channel operates independently with a normally-open configuration, allowing four separate signal paths to be individually controlled by dedicated logic inputs.
What package does the CD4066BNSR come in?
The CD4066BNSR is packaged in a 14-pin small outline package (JEDEC code R-PDSO-G14), suitable for surface-mount PCB assembly. It is RoHS compliant with JEDEC-609 e4 rating and a lead-free Pbfree designation for environmentally regulated markets.
Can the CD4066BNSR switch analog signals bidirectionally?
Yes, the CD4066BNSR is a bilateral (bidirectional) switch, meaning signals can pass through each channel in either direction. This makes it suitable for applications like analog multiplexers, sample-and-hold circuits, and two-way signal gating in audio and instrumentation designs.
What are typical applications for the CD4066BNSR?
Typical applications include analog signal multiplexing, audio channel selection, digital signal gating, communication interface switching, sample-and-hold circuits, and chopper-stabilized amplifier designs in consumer electronics, industrial instrumentation, and telecommunications equipment.
