Overview
The SN74LVC2G66DCTR is a dual bilateral analog switch manufactured by Texas Instruments, belonging to the LVC logic series. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and supports bidirectional signal transmission. The device features two independent SPST switches with low on-resistance of 15 ohms maximum. It utilizes an SOT-353 package for surface-mount installation. Key electrical parameters include a maximum propagation delay of 5.9 ns at 5 V and 8.3 ns at 3.3 V, with a bandwidth of 300 MHz. The component functions within a temperature range of -40°C to +125°C.
Feature Summary
- Dual bilateral analog switching capability for bidirectional signal paths
- Low on-resistance ensures minimal signal attenuation across the passband
- Wide single-supply voltage operation compatible with various logic families
- High-speed performance suitable for data acquisition and communication systems
Applications
- Battery-powered consumer electronics requiring low power consumption
- Signal routing in portable devices and mobile phones
- Data acquisition systems involving multiplexing
- Audio and video signal switching applications
Procurement Notes
Verify the specific ordering suffix to confirm the tape and reel quantity and packaging type. Ensure the component meets RoHS compliance requirements for your region. Check the datasheet revision date to confirm technical specifications match your design needs. Confirm the manufacturer source is authorized to avoid counterfeit risks.
Selection Notes
Select this component when a compact dual analog switch is required for low-voltage digital-to-analog interfacing. Compare on-resistance and leakage current specifications against system requirements. Consider the SOT-353 package size constraints during PCB layout. Verify that the operating voltage range aligns with the target signal levels.
Part Context
This part belongs to the SN74LVC2G66 family of dual bilateral analog switches. It serves as a solid-state alternative to mechanical relays in signal routing applications. The LVC series offers improved speed and lower power consumption compared to older logic families. It is designed for use in space-constrained portable electronic devices.
Replacement Considerations
Direct substitutes include the SN74LVC2G66DCUR variant which shares identical electrical characteristics but may differ in packaging configuration. Other family members like the SN74AUC2G66 offer similar functionality with different voltage ranges. Verify pin compatibility and thermal performance before substitution.
