Overview
The SN74LVC2G66YEAR is a dual bilateral analog switch from Texas Instruments, designed for high-speed signal routing in single-supply applications. It operates within a voltage range of 1.65 V to 5.5 V and features a low on-resistance of 10 Ohms maximum. The device supports a switching current of 100 mA and exhibits a typical propagation delay of 0.5 ns at 3 V with a 50 pF load. It is housed in an 8-XFBGA package and functions as a SPDT configuration.
Feature Summary
- Dual bilateral analog switching capability for signal path selection
- High-speed performance with typical 0.5 ns propagation delay
- Low on-resistance ensuring minimal signal attenuation
- Wide single-supply operating voltage range
Applications
- Portable equipment signal routing
- Video signal switching
- Audio signal switching
- Telecommunications equipment
Procurement Notes
Verify the specific YEAR suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure compatibility with the target PCB footprint and reflow soldering profile. Cross-reference the AEC-Q100 qualification status if automotive reliability is required for the specific revision.
Selection Notes
Select this component for applications requiring dual-channel analog switching with low insertion loss. Compare the 10 Ohm on-resistance against system requirements for signal integrity. Consider the 8-XFBGA package constraints for layout density. Evaluate the 1.65 V to 5.5 V supply range against available power rails.
Part Context
This part belongs to the SN74LVC2G66 family of dual bilateral analog switches. It shares functional similarities with the SN74LVC2G66DCUR but differs in packaging and specific suffix designations. The series is characterized by low power consumption and fast switching speeds suitable for modern digital systems.
Replacement Considerations
The SN74LVC2G66DCUR is a documented alternative within the same product family. Verify pinout compatibility and package dimensions before substitution. Check datasheet revisions for any changes in electrical characteristics or recommended operating conditions.
