Overview
The SN74LVC2G66DCTRG4 is a dual single-pole single-throw (SPST) analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 5.5V and features an on-resistance of 10 ohms maximum. The device supports bidirectional signal transmission with low capacitance of 6pF and offers a bandwidth of 300MHz. It includes overvoltage protection up to 5.5V and operates across a temperature range of -40°C to 85°C in an 8-VSSOP package.
Feature Summary
- Dual SPST configuration for independent signal routing
- Low on-resistance for minimal signal loss
- Bidirectional data flow support
- Overvoltage protection for input pins
Applications
- Portable equipment signal switching
- Battery-powered systems
- Video and audio signal routing
- Communication protocols interface
Procurement Notes
Verify the complete part number including suffixes such as 'R4' for RoHS compliance and 'TR' for tape-and-reel packaging. Confirm the manufacturer source is authorized to ensure component authenticity. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions before finalizing procurement specifications.
Selection Notes
Select this component when dual independent analog switching is required in space-constrained designs. Ensure the operating voltage aligns with the 1.65V to 5.5V range. Consider the 10-ohm on-resistance impact on signal integrity for high-frequency applications. Verify that the 8-VSSOP package fits the PCB layout constraints.
Part Context
This component belongs to the SN74LVC2G series of dual analog switches from Texas Instruments. It is part of the broader 74LVC logic family, designed for low-voltage CMOS applications. The device complements other LVC series components like the SN74LVC2G157 multiplexer for complex signal management systems.
Replacement Considerations
The SN74LVC2G66DCUR is a non-RoHS compliant alternative from the same manufacturer. Cross-reference with Nexperia's 74LVC2G66DC for pin-compatible options. Verify electrical parameters match before substitution.
