Overview
The TMUX1119DCKR is a single-channel, 2:1 precision analog multiplexer manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.08 V to 5.5 V. The device features a maximum on-state resistance of 4.9 Ohms and an extremely low on-state leakage current of 3 pA. It is housed in a compact SC70-6 surface-mount package. The component supports an operating temperature range from -40°C to +125°C and draws a maximum supply current of 1.4 µA.
Feature Summary
- Ultra-low leakage current specification suitable for high-impedance signal paths
- Low on-state resistance ensures minimal signal attenuation
- Wide single-supply voltage operation enables compatibility with various logic levels
Applications
- Battery-powered portable instrumentation
- Medical equipment requiring low leakage
- Process control systems
Procurement Notes
Verify the specific suffix DCKR corresponds to the SC70-6 package and tape-and-reel quantity when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration into production designs.
Selection Notes
Select this component when a single-pole double-throw configuration is required within a minimal footprint. The low leakage characteristic distinguishes it from standard switches, making it appropriate for applications where signal integrity at high impedances is critical compared to higher-leakage alternatives.
Part Context
This part belongs to the TMUX1119 family of 5-V precision multiplexers. It shares core electrical characteristics with variants such as the TMUX1119DBVR, differing primarily in the physical package type. The family is designed for general-purpose analog signal switching in space-constrained environments.
Replacement Considerations
The TMUX1119DBVR serves as a functional equivalent with identical electrical specifications but utilizes an SOT-23-6 package instead of the SC70-6 form factor. Verify pinout compatibility and thermal performance differences before substituting.
