Overview
The SN74LVC2G53DCTRE4 is a single-pole double-throw (SPDT) analog switch and 2:1 analog multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V, ensuring compatibility with various digital logic families. The device features low on-resistance of 13 ohms maximum at VCC = 3.3 V or 5.5 V, supporting high-speed signal routing. It includes an enable input for power-down control, reducing current consumption during inactive states. The component is housed in an 8-pin Small Outline package (SM8) and supports operation across an extended temperature range from -40°C to +85°C.
Feature Summary
- Supports bidirectional analog signal switching between two inputs and one output
- Provides low on-resistance for minimal signal attenuation
- Includes active-low enable pin for power management
- Compatible with standard CMOS logic levels
Applications
- Portable equipment requiring battery-powered signal routing
- Automotive infotainment systems for audio/video switching
- Industrial control systems for sensor data multiplexing
- Communication devices for line selection
Procurement Notes
Verify the E4 suffix indicates lead-free status and RoHS compliance per Texas Instruments documentation. Confirm the SM8 package variant matches the required footprint. Ensure the operating temperature range meets the specific environmental constraints of the target application. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications.
Selection Notes
Select this component when a compact SPDT switch is needed for low-voltage digital and analog signals. Consider the 13-ohm on-resistance for signal integrity requirements. Verify that the 5.5 V maximum rating accommodates the highest expected signal amplitude. Compare against similar LVC series parts if higher channel counts are required.
Part Context
This part belongs to the SN74LVC2G53 family of dual analog switches. The DCTR suffix denotes tape and reel packaging for surface-mount assembly. The E4 suffix typically signifies lead-free composition and environmental compliance. It is designed for space-constrained applications where low power consumption and small form factor are critical.
Replacement Considerations
SN74LVC2G53DCUR offers identical functionality in an 8-VSSOP package. SN74LVC2G53DBVR provides the same electrical characteristics in an SOT-23-6 package. Verify pinout compatibility and thermal performance before substituting.
