Overview
The SN74LVC2G53DCURG4 is a single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features an on-resistance of 13 ohms maximum. The device supports bidirectional signal transmission with low leakage current of 100 nA maximum. Key electrical parameters include a -3 dB bandwidth of 300 MHz, channel-to-channel matching of 2 ohms maximum, and crosstalk of -58 dB at 1 MHz. Switching times are specified as 4.5 ns for turn-on and 8 ns for turn-off. It functions reliably across an extended temperature range from -40°C to +85°C.
Feature Summary
- Provides SPDT switching capability with bidirectional signal flow support
- Features low on-resistance for minimal signal attenuation
- Offers high bandwidth suitable for RF and video applications
Applications
- Portable equipment requiring low power consumption
- Audio and video signal routing
- Communication systems
Procurement Notes
Verify the complete part number including the G4 suffix to ensure compliance with RoHS standards and lead-free manufacturing requirements. Confirm the package type matches the design footprint, specifically the 8-VSSOP configuration. Check datasheet revisions for any updates regarding assembly sites or material declarations before finalizing procurement orders.
Selection Notes
Select this component when a single SPDT switch is required within the LVC logic family voltage range. Ensure the application demands a maximum on-resistance of 13 ohms or lower. Verify that the operating temperature environment falls within the -40°C to +85°C industrial range. Consider the 300 MHz bandwidth limit for high-frequency signal integrity requirements.
Part Context
This part belongs to the SN74LVC2G53 series of single SPDT switches. It shares functional similarities with other devices in the LVC family but is distinct in its specific on-resistance and bandwidth characteristics. The DCUR suffix indicates the 8-VSSOP package variant, differentiating it from other package options like DCT or DBVR within the same logical function set.
Replacement Considerations
Direct replacements include SN74LVC2G53DCURE4 and SN74LVC2G53DCUTG4, which share identical electrical specifications and pinouts. Alternative packages such as SN74LVC2G53DCTRG4 offer the same functionality in different form factors. Cross-family substitutes like SN74AUC2G53DCUR provide similar switching but operate at lower voltages.
