Overview
The TMUX1109PWR is a dual 4:1 analog multiplexer switch manufactured by Texas Instruments, housed in a 16-pin TSSOP surface-mount package. It operates on a single supply voltage ranging from 1.08 V to 5.5 V or dual supplies up to ±2.75 V. The device features two independent channels with an on-state resistance maximum of 4.9 Ohms and low power consumption of 1 µA. Switching times are characterized by a maximum turn-on time of 20 ns and turn-off time of 9 ns. It supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Dual-channel architecture providing two independent 4:1 multiplexing paths within a compact footprint.
- Ultra-low leakage current specification suitable for high-impedance signal routing applications.
- Wide single-supply and dual-supply voltage compatibility enabling integration into various logic families.
Applications
- Data acquisition systems requiring signal selection from multiple sources.
- Industrial process control loops involving sensor multiplexing.
- Medical instrumentation utilizing low-leakage signal path switching.
Procurement Notes
Verify the specific suffix PWR indicates the TSSOP-16 package and tape-and-reel shipping configuration. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the ordering part number matches the required pinout and electrical specifications exactly.
Selection Notes
Select this component when dual 4:1 switching functionality is required with minimal on-resistance variation. Compare against the TMUX1109RSVR if a smaller UQFN package is preferred for space-constrained designs. Evaluate power supply requirements to ensure operation within the 1.08 V to 5.5 V range.
Part Context
This part belongs to the TMUX1109 series of general-purpose analog switches. It shares core electrical characteristics with other variants in the family but differs primarily in packaging options such as the RSVR variant which utilizes a UQFN-16 package instead of the TSSOP-16 form factor found in this model.
Replacement Considerations
The TMUX1109RSVR serves as a direct functional substitute offering identical electrical performance in a different UQFN-16 package. Designers must verify footprint compatibility and thermal dissipation requirements when substituting between TSSOP and UQFN packages.
