Overview
The MUX507IDWR is a precision analog multiplexer manufactured by Texas Instruments, featuring an SOIC-28 package. It provides two independent 8:1 multiplexing channels with a maximum supply voltage of 36 V and dual supply voltages ranging from 5 V to 18 V. The device exhibits extremely low on-state leakage current of 1 pA and typical off-isolation of -97 dB. Key electrical parameters include a maximum on-resistance of 430 Ohms, maximum propagation delay of 149 ns, and maximum charge/discharge time of 102 ns. It operates within a temperature range of -40°C to +125°C and draws a maximum supply current of 83 uA.
Feature Summary
- Ultra-low leakage current specification of 1 pA for high-impedance signal integrity
- High-voltage operation capability up to 36 V single or 18 V dual supply
- Precision analog switching with low on-resistance characteristics
- Low capacitance design supporting high-frequency signal transmission
Applications
- Data acquisition systems requiring high channel count and low leakage
- Medical instrumentation and patient monitoring equipment
- Industrial process control and sensor signal conditioning
- Test and measurement instruments demanding high isolation
Procurement Notes
Verify the specific suffix IDWR confirms the SOIC-28 package and industrial temperature grade (-40°C to +125°C). Confirm RoHS compliance status through official manufacturer documentation. Ensure ESD handling precautions are followed during assembly due to the sensitivity of CMOS analog switches. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.
Selection Notes
Select this component when high voltage tolerance (up to 36 V) and ultra-low leakage (1 pA) are critical requirements. Compare against the MUX506 if fewer channels are needed or the MUX509 if lower on-resistance is prioritized over leakage performance. Consider the SOIC-28 footprint constraints and thermal dissipation capabilities relative to the PCB layout. Verify that the 149 ns switching speed meets the system timing requirements.
Part Context
The MUX507IDWR belongs to the MUX50x family of precision analog multiplexers designed for high-performance applications. This series emphasizes low leakage and high voltage operation, distinguishing it from standard CMOS switches. The IDWR variant specifically denotes the industrial temperature range and surface-mount SOIC-28 packaging, providing a robust solution for demanding analog signal routing tasks in professional electronic systems.
Replacement Considerations
The MUX507IPWR serves as a pin-compatible alternative with identical electrical specifications but utilizes a TSSOP-28 package instead of SOIC-28. Designers must verify footprint compatibility before substitution. Other family members like the MUX506 offer similar features with different channel counts.
