Overview
The TMUX7208PWR is an 8:1 precision analog multiplexer manufactured by Texas Instruments, housed in a 16-pin TSSOP package. It operates on a single supply voltage ranging from 1.62 V to 5.5 V or dual supplies up to ±2.75 V. The device features low on-state resistance of 4 Ohms maximum and ultra-low on-state leakage current of 3 pA. Key electrical parameters include a maximum operating frequency of 200 MHz, propagation delay of 20 ns, and power consumption of 1 µA. It supports an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Ultra-low on-state leakage current for high-precision signal integrity
- Low on-state resistance ensuring minimal signal attenuation
- High bandwidth supporting wideband signal transmission
- Robust latch-up immunity for reliable operation
Applications
- Data acquisition systems requiring precise signal routing
- Medical instrumentation with strict leakage current constraints
- Industrial process control signal conditioning
- Automotive sensor interface circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and thermal specifications. Ensure the procurement channel provides valid traceability documentation. Confirm that the component meets RoHS compliance requirements as specified in the technical data. Cross-reference the part number with the latest revision history to avoid obsolete variants.
Selection Notes
Select this component when application requirements demand extremely low leakage currents combined with low on-resistance. Verify that the system voltage aligns with the 1.62 V to 5.5 V single-supply range. Consider the TSSOP-16 package dimensions for PCB layout constraints. Evaluate the 200 MHz bandwidth against the highest frequency component in the signal path to prevent distortion.
Part Context
This part belongs to the TMUX72xx series of precision analog switches. It shares the TSSOP-16 footprint with other members like the TMUX1108 but offers superior leakage performance. The series is designed for applications where signal fidelity is critical. It complements higher-voltage options like the TMUX8108 by focusing on low-voltage precision rather than high-voltage handling.
Replacement Considerations
Direct substitutes within the same family include the TMUX7208PW (SOIC-16 package). For equivalent performance in different packages, verify the TMUX1108 for similar switching characteristics, though leakage specs may differ. Always validate pin-to-pin compatibility and thermal dissipation capabilities before substitution.
