Overview
The TS5A3154DCUR is a single-channel SPDT analog switch IC manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65 V to 5.5 V, making it suitable for low-voltage portable applications. The device features a maximum on-resistance of 1.1 Ohms and supports a continuous DC switch current of 100 mA. Key timing specifications include a maximum turn-on time of 8 ns and a maximum turn-off time of 12.5 ns. It is housed in an 8-pin VSSOP package with a maximum quiescent current of 100 nA. The component functions within a temperature range of -40°C to +85°C.
Feature Summary
- Ultra-low on-resistance ensures minimal signal attenuation across the switching path.
- Low power consumption design supports battery-operated systems through reduced quiescent current.
- Fast switching speeds facilitate high-frequency signal routing and data transmission.
Applications
- Portable consumer electronics requiring signal multiplexing
- Audio and video signal routing in compact devices
- Communication equipment interface switching
Procurement Notes
Verify the specific suffix DCUR corresponds to the VSSOP-8 package and reel/cut-tape packaging format when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the supplier provides valid traceability records matching the Texas Instruments part number to avoid counterfeit components.
Selection Notes
Select this component when a single SPDT configuration is required for signals between 1.65 V and 5.5 V. Consider the 1.1 Ohm on-resistance limit for applications sensitive to insertion loss. Evaluate the 100 mA continuous current capability against load requirements. The VSSOP-8 package is appropriate for space-constrained PCB layouts compared to larger SOIC alternatives.
Part Context
This part belongs to the TS5A3154 series of analog switches from Texas Instruments. The series focuses on low-power, high-performance signal switching for mobile and industrial applications. The DCUR suffix specifically denotes the tape-and-reel packaging variant, distinguishing it from cut-tape or tube options within the same electrical specification set.
Replacement Considerations
Direct pin-compatible substitutes within the same family may include other TS5A315x variants if channel count or configuration differs. Verify that alternative parts maintain the 1.65 V minimum operating voltage and similar on-resistance characteristics to ensure circuit compatibility without redesign.
