The TS3A27518ERTWR is a 6-channel bidirectional 1:2 multiplexer-demultiplexer from Texas Instruments, packaged in a 24-WQFN with tape-and-reel packing. Operating from a single 1.65 V to 3.6 V supply, this device handles both digital and analog signals up to VCC in either direction, featuring integrated IEC 61000-4-2 ESD protection, 1.8 V logic-compatible control inputs, and a 240 MHz bandwidth for high-speed rail-to-rail signal handling across all six channels.
The TS3A27518ERTWR is primarily deployed in SD-SDIO and MMC two-port multiplexer applications where a single host controller must interface with multiple memory cards or peripherals. It is extensively used in PC VGA video multiplexing for video systems, LCD televisions, LCD monitors, and notebook docking stations for switching between multiple audio-video sources. Additional applications include battery-powered portable devices, industrial signal routing, and general-purpose analog/digital signal switching in mixed-voltage systems.
Frequently Asked Questions
Q1: What is the operating voltage range of the TS3A27518ERTWR?
The device operates from a single 1.65 V to 3.6 V supply, making it compatible with 1.8 V, 2.5 V, and 3.3 V logic systems.
