Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'MT' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as manufacturing processes may evolve. Check for obsolescence notices or production change notifications prior to final design approval to ensure long-term availability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a 5V logic interface is required for analog switching. Ensure the application voltage does not exceed the 5.5 V maximum rating. Consider the 70 Ohm on-resistance for signal attenuation requirements. Verify that the SOIC-14 package dimensions fit the target PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the CD74HCT4066 family of analog switches. It is functionally similar to the HC variant but optimized for 5V operation with TTL-compatible input thresholds. The MT suffix specifically denotes the tape and reel packaging format, distinguishing it from tube-packaged versions like the M suffix.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between CD74HCT4066MT and CD74HC4066MT?

The primary difference is the input logic threshold. The HCT version requires a 5V supply and has TTL-compatible inputs, while the HC version supports a wider voltage range (2V to 10V).

Does the MT suffix indicate a different internal circuit than the M suffix?

No, the internal circuitry is identical. The MT suffix only specifies that the device is packaged in tape and reel format for automated assembly, whereas M indicates tube packaging.
