Overview
The MUX36D08IRSNR is a dual 4:1 analog multiplexer switch IC from Texas Instruments, housed in a 20-pin WQFN package. It operates on a single supply voltage ranging from 10 V to 36 V or a dual supply of ±5 V to ±18 V. The device features a maximum on-state resistance of 430 Ohms and supports a wide operating temperature range from -40°C to +125°C. Key electrical parameters include a maximum power supply current of 77 uA, a typical off-isolation of -96 dB, and switching times with a maximum turn-on time of 149 ns and turn-off time of 102 ns.
Feature Summary
- Dual independent 4:1 multiplexing channels for signal routing
- High-voltage operation capability up to 36 V
- Low quiescent current consumption for power efficiency
- Wide industrial temperature range support
Applications
- Industrial process control signal conditioning
- Data acquisition systems requiring high-voltage input switching
- Test and measurement equipment front-ends
Procurement Notes
Verify the exact suffix 'IRSNR' against the manufacturer's official datasheet to confirm the specific tape-and-reel packaging and commercial grade temperature rating. Ensure the ordering part number matches the required pinout and thermal pad configuration for your PCB layout.
Selection Notes
Select this component when dual isolated 4:1 switching paths are required within a compact footprint. Compare the 430 Ohm on-resistance against system signal integrity requirements. Verify that the 36 V absolute maximum rating aligns with the highest expected signal voltage levels in the application circuit.
Part Context
This part belongs to the MUX36D04/MUX36D08 family of high-voltage analog switches. It shares architectural similarities with the MUX36S series but offers distinct channel configurations. The WQFN package provides thermal performance suitable for dense surface-mount assemblies.
Replacement Considerations
Direct pin-compatible alternatives within the same family include the MUX36D04 variants for reduced channel counts. For single-channel applications, consider the MUX36S08. Always verify package dimensions and thermal characteristics before substitution.
