Overview
The MUX36S08IRUMR is a precision analog multiplexer switch IC manufactured by Texas Instruments, featuring an 8:1 channel configuration in a 16-pin WQFN package. It operates on a single supply voltage ranging from 10 V to 36 V or dual supplies of ±5 V to ±18 V. The device exhibits low on-state leakage current and high off-isolation, with a maximum on-resistance of 250 Ohms. Switching performance includes a maximum turn-on time of 151 ns and a maximum turn-off time of 90 ns. It supports an operating temperature range from -40°C to +125°C and draws a maximum supply current of 83 µA.
Feature Summary
- Provides 8:1 signal routing capability within a compact surface-mount footprint
- Supports wide single and dual power supply configurations for flexible system integration
- Delivers high isolation and low leakage characteristics suitable for precision applications
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial process control instrumentation
- Medical equipment signal conditioning circuits
Procurement Notes
Verify the specific suffix IRUMR against official datasheets to confirm the WQFN-16 package variant and industrial temperature grade. Ensure compatibility with standard reflow soldering profiles for QFN packages. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when an 8:1 multiplexing ratio is required with a maximum supply voltage of 36 V. Compare the 250 Ohm on-resistance and 151 ns switching speed against system bandwidth and latency requirements. Consider the WQFN-16 package for space-constrained designs while verifying thermal dissipation needs at the specified operating temperatures.
Part Context
This part belongs to the MUX36S08 series of low-capacitance, low-leakage analog multiplexers. It shares functional similarities with other members like the MUX36D04 but offers higher channel density. The series is designed for applications demanding high precision and wide dynamic range operation under varying supply conditions.
Replacement Considerations
Direct substitutes include the MUX36S08IPWR (TSSOP-16 package) and MUX36S08IRSR (WQFN-16 package). Verify pinout compatibility and package dimensions when transitioning between TSSOP and WQFN variants to ensure mechanical fit.
