Overview
The TMUX4827YBHR is a Texas Instruments CMOS multiplexer featuring two independent 2:1 single-pole double-throw (SPDT) switch channels. It operates on a single supply voltage ranging from 1.8V to 5.5V while supporting bidirectional analog and digital signals extending beyond the supply rails from -12V to +12V. The device incorporates an ultra-low on-resistance of 0.13Ω with minimal flatness, ensuring high signal integrity. Key electrical specifications include a maximum transition time of 220µs, off-isolation of -55dB, and a bandwidth of 72MHz. It provides powered-off protection up to ±12V and includes over-temperature protection.
Feature Summary
- Bidirectional signal support exceeding supply rails
- Ultra-low on-resistance for precision applications
- Powered-off protection isolating switches at zero supply
- Break-before-make switching logic
Applications
- Audio input or output switching
- Ultrasonic gas flow transmitters
- Analog input modules
- Industrial module detection
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape-and-reel configuration. Confirm that the component meets RoHS compliance requirements for your target assembly process. Cross-reference the datasheet revision history to validate any recent changes to electrical characteristics or pin definitions before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring signal paths that exceed the logic supply voltage range. Ensure the application environment stays within the specified -40°C to +125°C operating temperature limits. Verify that the load current does not exceed the continuous current ratings defined in the thermal information section to prevent junction overheating.
Part Context
This part belongs to the TMUX4827 series of multiplexers designed for high-performance signal routing. It utilizes a DSBGA-9 package to provide a compact footprint suitable for space-constrained designs. The series emphasizes low distortion and high isolation capabilities for sensitive analog signal transmission.
Replacement Considerations
Consult the manufacturer's product selection guide for alternative parts within the same family that may offer different channel counts or package options. Verify pin compatibility and electrical parameter equivalence if substituting with other Texas Instruments multiplexer devices.
