Overview
The TS3A27518EZQSR is a bidirectional, 6-channel, 1:2 multiplexer-demultiplexer manufactured by Texas Instruments. It operates from a single supply voltage of 1.65 V to 3.6 V and handles both digital and analog signals up to VCC in either direction. The device features integrated IEC Level-4 ESD protection and control inputs compatible with 1.8-V logic thresholds. It utilizes two control pins to manage three 1:2 muxes simultaneously, alongside an enable pin for high-impedance mode. The component is housed in a 24-pin BGA MicroStar Junior package measuring 3.00 mm x 3.00 mm.
Feature Summary
- Integrated IEC Level-4 ESD protection on NC/NO ports
- Low-capacitance switches supporting high-speed rail-to-rail signal handling
- Bidirectional signal transmission capability across the full supply range
- Control inputs compatible with 1.8-V logic and tolerant to 3.6 V
Applications
- SD-SDIO and MMC Two-Port MUX
- PC VGA Video MUX-Video Systems
- Audio and Video Signal Routing
Procurement Notes
Verify the specific ordering suffix ZQSR corresponds to the 24-pin BGA MicroStar Junior package configuration before procurement. Confirm that the intended application environment aligns with the specified operating temperature range and voltage requirements. Ensure all unused digital inputs are properly terminated to maintain stable operation.
Selection Notes
Select this component when a compact 6-channel analog switch with robust ESD protection is required. The low capacitance and high bandwidth make it suitable for high-speed data lines. Verify that the system's control logic levels match the 1.8-V compatibility specifications to ensure reliable switching performance.
Part Context
This part belongs to the TS3A27518E family of multiplexers designed for expanding multi-bit interfaces like SDIO and qSPI. It allows host controllers to connect to multiple peripherals or cards. The device simplifies signal routing in portable electronics by consolidating multiple channels into a small footprint while maintaining signal integrity.
Replacement Considerations
Direct replacements include other variants within the TS3A27518E family such as TS3A27518ERTWRG4 or TS3A27518EPWR, provided the package type matches the design constraints. Cross-referencing electrical characteristics and pinout configurations is essential when substituting with components from different manufacturers.
