Overview
The SN74AUC2G53DCURG4 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 supports an operating temperature range from -40°C to +85°C. The device features a maximum on-resistance of 15 ohms and a channel-to-channel matching of 1 ohm. Key electrical parameters include a -3dB bandwidth of 500MHz, leakage current of 1µA, and crosstalk of -60dB at 1MHz. Switching times are specified as 2.2ns for turn-on and 2.3ns for turn-off. It is housed in an 8-VSSOP package.
Feature Summary
- Supports low-voltage operation down to 0.8V for compatibility with modern portable systems
- Provides high-speed signal switching with 500MHz bandwidth and sub-3ns switching times
- Ensures signal integrity through low on-resistance and tight channel-to-channel matching
Applications
- Battery-powered consumer electronics requiring low voltage analog switching
- Portable devices utilizing low-voltage logic interfaces
- Signal routing in mobile communication equipment
Procurement Notes
Verify the G4 suffix indicates RoHS compliance and green material status per Texas Instruments specifications. Confirm the DCUR suffix corresponds to the VSSOP-8 package variant. Ensure the component matches the official datasheet parameters for the AUC series before integration into designs.
Selection Notes
Select this component when designing circuits that require analog switching below 2.7V. Compare against the SN74LVC2G53 if higher voltage tolerance up to 5.5V is needed. Consider the SN74AUC2G53YZPR if a DSBGA package is preferred over VSSOP for space constraints.
Part Context
This part belongs to the Texas Instruments SN74AUC2G53 family of analog switches. It shares functional characteristics with other members like the SN74AUC2G53DCUR but differs in packaging and compliance suffixes. The family is designed for low-power applications requiring fast switching speeds in small form factors.
Replacement Considerations
The SN74AUC2G53DCUR is a pin-compatible alternative without the G4 suffix. For different packaging, the SN74AUC2G53YZPR offers the same functionality in an 8-DSBGA package.
