Overview
The TMUX1134PWR is a low-power, high-speed analog switch IC manufactured by Texas Instruments. It features four independent single-pole double-throw (SPDT) switches housed in a TSSOP-20 package. The device supports a wide supply voltage range from 1.08 V to 5.5 V for single-supply operation and ±1.375 V for dual-supply configurations. Key electrical specifications include a maximum on-state resistance of 4 Ohms, a maximum power supply current of 1 µA, and a DC switch current capability of 30 mA. It operates within an extended temperature range of -40°C to +125°C.
Feature Summary
- Ultra-low quiescent current consumption suitable for battery-powered applications
- High bandwidth and fast switching speeds for signal integrity
- Low on-state resistance ensuring minimal signal attenuation
- Rail-to-rail input/output capability across the full supply range
Applications
- Portable medical instrumentation
- Industrial process control systems
- Automotive infotainment and sensor interfaces
- Test and measurement equipment
Procurement Notes
Verify the specific suffix 'PWR' corresponds to the TSSOP-20 tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the ordering part number matches the required channel count and package type for your design requirements.
Selection Notes
Select this component when designing circuits requiring multiple SPDT switching functions with minimal power draw. The low on-resistance makes it suitable for precision signal paths. Consider the TSSOP-20 thermal performance if operating at the upper limits of the temperature range. Verify that the 30 mA DC switch current meets the load requirements of the connected signals.
Part Context
This device belongs to the TMUX113x family of multiplexer switches designed for space-constrained and power-sensitive applications. The TMUX1134 specifically provides four channels, offering a compact alternative to discrete switching solutions. It complements other Texas Instruments analog switches by providing high speed alongside ultra-low static power consumption.
Replacement Considerations
Consult Texas Instruments application notes for direct pin-compatible alternatives within the TMUX series. Verify that any substitute maintains the same 4 Ohm max on-resistance and 1.08 V minimum supply voltage. Ensure the replacement package matches the TSSOP-20 footprint and thermal characteristics.
