Overview
The SN74AUC2G53DCURE4 is a single-pole, double-throw (SPDT) analog switch or 2:1 analog multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 0.8V to 2.7V and features an on-resistance of 15 ohms maximum. The device supports a -3dB bandwidth of 500MHz with low channel capacitance values of 3pF and 4.5pF. Leakage current is limited to 1µA maximum. It functions across an extended temperature range from -40°C to +85°C and is housed in an 8-VSSOP package.
Feature Summary
- Provides SPDT switching or 2:1 multiplexing functionality for signal routing applications
- Operates at ultra-low supply voltages starting from 0.8V
- Features high-speed performance with 500MHz bandwidth and low propagation delay
Applications
- Portable battery-powered equipment requiring low voltage operation
- Signal routing in mobile communications devices
- Consumer electronics utilizing space-constrained surface mount packages
Procurement Notes
Verify the specific ordering suffix DCURE4 against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and lead-free status. Ensure compatibility with standard surface-mount assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.
Selection Notes
Select this component when designing circuits that require low-voltage analog switching with minimal signal distortion. The 15-ohm on-resistance and 500MHz bandwidth make it suitable for high-frequency signal paths. Consider the 8-VSSOP package dimensions for PCB layout constraints and thermal management requirements in dense assemblies.
Part Context
This part belongs to the SN74AUC2G53 family of analog switches. It shares functional characteristics with variants such as SN74AUC2G53DCUR and SN74AUC2G53YZPR, differing primarily in packaging style and manufacturing revisions. The E4 suffix typically denotes a lead-free and RoHS-compliant version within the Texas Instruments logic portfolio.
Replacement Considerations
Direct pin-compatible alternatives include SN74AUC2G53DCUR and SN74AUC2G53DCTRG4. Verify electrical parameters and package dimensions before substitution.
