Overview
The MUX507IPW is an analog multiplexer switch integrated circuit manufactured by Texas Instruments, housed in a 28-pin TSSOP package. It features a dual 8:1 configuration, providing eight independent channels per section. The device operates with a single supply voltage ranging from 10 V to 36 V or dual supplies of ±5 V to ±18 V. Key electrical specifications include a maximum on-state resistance of 430 Ohms, a typical off-isolation of -97 dB, and a maximum power supply current of 83 uA. Switching performance is defined by a maximum turn-on time of 149 ns and a maximum turn-off time of 102 ns. The component supports an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Dual 8:1 multiplexer architecture enabling two independent signal routing paths within a single package.
- High-voltage operation capability supporting up to 36 V single supply or ±18 V dual supply rails.
- Low power consumption design with minimal quiescent current draw suitable for battery-operated systems.
- Robust isolation characteristics ensuring effective signal separation between active and inactive channels.
Applications
- Data acquisition systems requiring multi-channel signal selection.
- Industrial process control instrumentation for sensor input switching.
- Medical equipment involving precise analog signal routing.
- Automotive electronic control units managing multiple sensor inputs.
Procurement Notes
Verify the specific suffix IPW confirms the TSSOP-28 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure handling procedures account for moisture sensitivity classification during storage and assembly processes to maintain component reliability.
Selection Notes
Select this part when a dual 8:1 topology is required rather than a single 16:1 configuration. Compare against the MUX506IPWR if a single 16:1 channel count is sufficient for the application. Consider the MUX508IPW if only one 8:1 mux is needed to reduce board space. Evaluate the higher on-resistance of 430 Ohms against system accuracy requirements compared to lower resistance alternatives.
Part Context
This component belongs to the MUX50x series of high-voltage analog multiplexers from Texas Instruments. The series includes variants like the MUX506, MUX508, and MUX509, which share similar high-voltage capabilities but differ in channel count and configuration. The MUX507 specifically addresses designs needing two separate 8-to-1 switching functions without occupying two separate IC footprints.
Replacement Considerations
The MUX506IPWR serves as a functional alternative if a single 16:1 multiplexer configuration meets the design requirements instead of two 8:1 sections. Verify pin compatibility and electrical parameter alignment before substitution.
