Overview
The SN74LVC2G53DCTR is a single-channel analog switch manufactured by Texas Instruments, featuring Single-Pole Double-Throw (SPDT) and 2:1 Multiplexer/Demultiplexer configurations. It operates within a supply voltage range of 1.65V to 5.5V. Key electrical parameters include a maximum on-resistance of 13 ohms, a channel-to-channel matching of 2 ohms, and a -3dB bandwidth of 300MHz. The device exhibits a maximum leakage current of 100nA and supports propagation delays of 4.5ns (Ton) and 8ns (Toff). It is housed in an 8-SM8 package and functions reliably across a temperature range of -40°C to 85°C.
Feature Summary
- Supports SPDT switching and 2:1 multiplexing/demultiplexing topologies for signal routing
- Provides low on-resistance with tight channel-to-channel matching for signal integrity
- Operates across a wide supply voltage range compatible with various logic families
Applications
- Portable equipment requiring low power consumption
- Battery-powered systems utilizing low-voltage operation
- Signal routing in communication devices
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and environmental compliance. Confirm that the component meets RoHS3 standards as indicated in public datasheets. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a single-channel SPDT or 2:1 mux function is required in space-constrained designs. Ensure the application voltage falls within the 1.65V to 5.5V range. Consider the 8-SM8 package dimensions for PCB layout compatibility. Verify that the 300MHz bandwidth and 13-ohm on-resistance meet the signal integrity requirements of the target circuit.
Part Context
This component belongs to the SN74LVC2G53 family of analog switches from Texas Instruments. It shares functional similarities with variants such as SN74LVC2G53DCUR and SN74LVC2G53YZPR, differing primarily in package type and manufacturing revisions. The DCTR suffix specifically denotes the tape-and-reel packaging format suitable for automated assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers include SN74LVC2G53DCUR and SN74LVC2G53YZPR. These alternatives offer identical logical functionality but differ in physical packaging, requiring verification of footprint compatibility during replacement.
