Overview
The SN74LVC2G66DCUTG4 is a dual bilateral analog switch manufactured by Texas Instruments, belonging to the SN74LVC2G series. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. The device features two independent SPST switches with a maximum on-resistance of 10 ohms and a channel-to-channel matching of 2 ohms. Key electrical parameters include a -3dB bandwidth of 300 MHz, off-state leakage current of 100 nA, and switching times of 3.9 ns (Ton) and 6.3 ns (Toff). It is housed in an 8-VSSOP package.
Feature Summary
- Dual bilateral analog switch architecture providing independent signal path control
- Low on-resistance characteristic ensuring minimal signal attenuation
- High-speed performance suitable for broadband applications
- Wide supply voltage compatibility for diverse logic families
Applications
- Signal routing in portable consumer electronics
- Battery-powered systems requiring low power consumption
- Audio and video signal switching applications
- Communication equipment signal path management
Procurement Notes
Verify the specific suffix 'TG4' against official Texas Instruments documentation to confirm RoHS compliance and manufacturing details. Ensure the ordering part number matches the exact package type and tape/reel specifications required for your assembly process. Cross-reference with authorized distributors to confirm current availability status.
Selection Notes
Select this component when dual independent analog switching is required within a compact surface-mount footprint. Consider the 10-ohm on-resistance and 300 MHz bandwidth for high-frequency signal integrity. Compare against automotive-grade variants if extended temperature ranges or AEC-Q100 qualification are necessary for the target application environment.
Part Context
This component is part of the SN74LVC2G family of low-voltage CMOS logic devices. It shares functional similarities with other LVC series switches but is distinct from digital logic gates like inverters or buffers. The DCUT variant specifically denotes the 8-VSSOP package configuration used in space-constrained designs.
Replacement Considerations
SN74LVC2G66DCUR is a manufacturer-recommended alternative with identical functionality. SN74LVC2G66QDCURQ1 offers automotive qualification with slightly higher on-resistance. Nexperia NL7WB66USG is a direct pin-compatible substitute from another vendor.
