Overview
The TMUX1104DQAR is a 5-V, low-leakage-current, 4:1 precision analog multiplexer manufactured by Texas Instruments. It features a single channel with a 4-to-1 configuration, supporting a supply voltage range of 1.08 V to 5.5 V. The device exhibits an on-state leakage current of 3 pA and a maximum on-resistance of 4.9 Ohms. Switching performance includes a maximum turn-on time of 18 ns and a maximum turn-off time of 9 ns. It operates within a temperature range of -40°C to +125°C and is housed in an MSOP-10 package.
Feature Summary
- Ultra-low on-state leakage current of 3 pA for high-impedance signal integrity
- Precision switching capability with low on-resistance for accurate signal routing
- Wide single-supply operating voltage range compatible with various logic levels
Applications
- Data acquisition systems requiring low leakage
- Battery-powered instrumentation
- Medical equipment signal conditioning
Procurement Notes
Verify the specific suffix DQAR against the manufacturer datasheet to confirm the MSOP-10 package and tape-and-reel packaging details. Ensure the component meets RoHS compliance requirements as specified in the official documentation before integration into production designs.
Selection Notes
Select this component when designing circuits that demand minimal signal distortion due to leakage current. The wide supply voltage range allows flexibility in system power architecture. Confirm that the MSOP-10 footprint aligns with the PCB layout constraints and thermal management requirements of the target application.
Part Context
This part belongs to the TMUX1104 family of precision multiplexers from Texas Instruments. It serves as a compact solution for routing multiple analog signals to a single output line. The device is designed for applications where power consumption and signal accuracy are critical constraints.
Replacement Considerations
The TMUX1104DGSR is a verified substitute offering identical electrical specifications and functionality. Verify pin compatibility and package dimensions (MSOP-10) to ensure direct interchangeability in existing layouts.
