CD74HC4066M

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4066M is a high-speed CMOS logic quad bilateral switch manufactured by Texas Instruments. It features four independent single-pole single-throw (SPST) analog switches in a 14-pin SOIC package. The device operates on a single supply voltage ranging from 2 V to 10 V. Key electrical parameters include a maximum on-resistance of 70 ohms, a bandwidth of 200 MHz, and a maximum leakage current of 100 nA. Propagation delays are specified with a maximum turn-on time of 100 ns and a maximum turn-off time of 150 ns. The component supports an operating temperature range from -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as the base model number may correspond to different packaging options such as tubes or reels across distributors. Confirm RoHS compliance status and lead times directly with authorized suppliers, noting that availability may vary due to production lifecycle changes. Ensure the selected part matches the required pin configuration and thermal specifications for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring low on-resistance and high bandwidth within a standard 14-pin surface-mount footprint. Compare against the CD74HCT4066M if strict 5V logic compatibility is mandatory, as the HC series supports a wider voltage range. Evaluate the TSSOP variants like CD74HC4066PWR if space-constrained layouts necessitate a smaller package profile while maintaining similar electrical characteristics.
