Overview
The TS5A3157DCKRE4 is a single-channel SPDT analog switch manufactured by Texas Instruments, designed for low-voltage portable applications. It operates within a supply voltage range of 1.65V to 5.5V and features a maximum on-resistance of 10 ohms. The device provides bidirectional signal transmission with excellent total harmonic distortion performance. Key electrical parameters include a -3dB bandwidth of 371MHz, charge injection of -21pC, and off-state leakage current of 30nA. Switching times are specified at 5ns (Ton) and 3.4ns (Toff). It is housed in a compact SC-70-6 package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Low on-resistance of 10 ohms ensures minimal signal loss in the conduction path.
- High bandwidth of 371MHz supports high-frequency signal integrity.
- Low charge injection of -21pC minimizes signal distortion during switching events.
- Wide single-supply operation allows compatibility with various logic levels.
Applications
- Portable audio equipment requiring low distortion
- Battery-powered consumer electronics
- Signal routing in communication networks
Procurement Notes
Verify the component authenticity by checking the manufacturer's marking code against official documentation. Confirm the RoHS compliance status indicated by the E4 suffix. Ensure the SC-70-6 package dimensions match the design footprint requirements. Validate the operating temperature range suitability for the specific environmental conditions of the target application.
Selection Notes
Select this component when a single-pole double-throw configuration is required for low-voltage analog signal routing. The 10-ohm on-resistance makes it suitable for applications where moderate signal attenuation is acceptable. Consider the 371MHz bandwidth for signals requiring high-frequency response. The SC-70-6 package is ideal for space-constrained designs compared to larger packages like SOT-23-6.
Part Context
This part belongs to the TS5A3157 family of analog switches from Texas Instruments. It shares functional similarities with other members such as TS5A3159 but differs in on-resistance specifications. The E4 suffix denotes lead-free packaging compliant with RoHS standards. It serves as a solution for signal multiplexing in portable devices where power consumption and size are critical constraints.
Replacement Considerations
Potential substitutes include TS5A3157DBVR and TS5A63157DCKR. Verify pinout compatibility and electrical parameter alignment before substitution. Check if alternative packages meet the physical space requirements of the existing design.
