Overview
The SN74LVC2G66DCUT is a dual bilateral analog switch manufactured by Texas Instruments, belonging to the SN74LVC2Gxx family. 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 low on-resistance of 15 Ω (maximum) at VCC = 3.3 V. Key electrical parameters include a maximum channel-to-channel matching of 5 Ω, off-state leakage current of 100 nA, and a bandwidth of 300 MHz. Switching times are specified as 5.9 ns for turn-on and 8.3 ns for turn-off. The component is housed in an 8-VSSOP package.
Feature Summary
- Dual bilateral analog switching capability allowing signal routing in both directions
- Low on-resistance characteristic ensuring minimal signal attenuation across the passband
- Wide supply voltage compatibility supporting systems from 1.65 V to 5.5 V
- High-speed performance with 300 MHz bandwidth for efficient signal transmission
Applications
- Portable equipment requiring low-voltage operation and space-efficient packaging
- Battery-powered systems utilizing single-supply configurations
- Automotive applications meeting AEC-Q100 qualification standards
- Communication protocols involving high-frequency signal switching
Procurement Notes
Verify the specific ordering suffix DCUT corresponds to the VSSOP-8 package and cut-tape or reel packaging options when sourcing. Confirm RoHS compliance status and manufacturing date codes through authorized distributors to ensure component authenticity. Cross-reference the manufacturer part number with official datasheets to validate pinout and electrical specifications before integration into design files.
Selection Notes
Select this component when designing circuits that require bidirectional analog signal routing under low-voltage conditions. The 15 Ω on-resistance makes it suitable for general-purpose signal switching where moderate impedance is acceptable. Consider the 8-VSSOP package dimensions for PCB layout constraints. Ensure the input logic levels remain compatible with the system's control voltages to prevent unintended switching states during operation.
Part Context
This device is part of the SN74LVC2Gxx series of dual analog switches from Texas Instruments. It shares functional similarities with other members like the SN74LVC2G66QDCURQ1, which offers automotive-grade qualification. The LVC technology provides improved performance over older logic families while maintaining compatibility with standard CMOS and TTL inputs.
Replacement Considerations
The SN74LVC2G66QDCURQ1 serves as a qualified alternative for automotive applications requiring AEC-Q100 certification. Other variants within the SN74LVC2Gxx family may offer different package options or temperature ranges but maintain similar electrical characteristics.
