Key Features

  • 4 independent SPST bilateral switch channels enabling flexible signal routing in analog multiplexer and signal conditioning designs
  • 40 MHz analog signal bandwidth supports audio, video, and intermediate-frequency switching without significant insertion loss
  • Wide supply voltage range compatible with both single-supply and dual ±5 V configurations for mixed-signal systems

Applications

The CD4066BNS is widely used in analog signal routing for audio mixers, data acquisition front ends, and communication systems where 4 independent SPST channels with 40 MHz bandwidth are needed. It performs effectively in sample-and-hold circuits, analog multiplexers, and CMOS logic signal routing on a single PCB. The 14-pin SO package suits space-constrained designs in consumer electronics and industrial instrumentation.

Frequently Asked Questions

What is the analog bandwidth of the CD4066BNS, and what signal types can it switch?

The CD4066BNS has a nominal bandwidth of 40 MHz, allowing it to switch audio, video, and intermediate-frequency analog signals without significant attenuation. It handles both analog and digital signals from 0 V up to the positive supply rail, making it a versatile SPST switch for mixed-signal boards.

How many independent switch channels does the CD4066BNS provide and how are they configured?

The CD4066BNS contains 4 independent SPST bilateral switch channels, each controlled by a separate logic input. All 4 channels share a common 14-pin SOIC package, enabling compact quad-channel signal routing without discrete relays or separate switch ICs.

Can the CD4066BNS operate from a single supply voltage, and what supply range is supported?

Yes, the CD4066BNS supports single-supply operation as well as dual supplies down to -5 V on the negative rail. The CMOS design allows the device to switch signals across the full supply span, and its low quiescent current makes it power-efficient in battery-operated instruments and portable audio equipment.
