Overview
The TS3A27518ERTWR is a hex single-pole double-throw (SPDT) analog multiplexer/demultiplexer manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65 V to 3.6 V, making it suitable for low-voltage portable applications. The device features six independent channels with a 240 MHz bandwidth and a maximum on-resistance of 7.6 Ohms. Switching times are specified at a maximum of 59 ns for turn-on and 60.6 ns for turn-off. It is housed in a 24-pin WQFN package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Provides six independent SPDT signal paths for flexible routing
- Supports low-voltage operation down to 1.65 V
- Delivers high-speed signal switching with 240 MHz bandwidth
Applications
- Portable multimedia devices requiring signal routing
- Audio and video signal path switching
- Data acquisition systems
Procurement Notes
Verify the specific suffix 'ERTWR' corresponds to the WQFN-24 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements during storage and handling. Ensure the ordering part number matches the exact pinout and electrical specifications required for the design.
Selection Notes
Select this component when a compact solution for multiple analog signal paths is needed within a 1.65 V to 3.6 V supply range. Compare on-resistance and bandwidth requirements against other family members like the TS3A27518EPWR if TSSOP packaging is preferred. Verify thermal performance needs for the WQFN package in the target application environment.
Part Context
This part belongs to the TS3A27518E series of analog switches. It shares functional similarities with variants such as TS3A27518ERTWRG4 and TS3A27518ETRTWRQ1, differing primarily in packaging, lead content, or automotive qualification. The ERTWR designation specifically identifies the commercial grade version in the WQFN-24 form factor.
Replacement Considerations
Direct substitutes include TS3A27518ERTWRG4 for lead-free compliance variations. For automotive applications, consider TS3A27518ETRTWRQ1. Alternative packages like TS3A27518EPWR offer the same functionality in a TSSOP-24 housing.
