Overview
The MPC507AU is an analog multiplexer switch IC from the Texas Instruments MPC507 series, housed in a 28-pin SOIC package. It features an 8-channel configuration with a 2 x 8:1 topology and supports dual supply voltages ranging from 15 V to 15 V. The device operates within a temperature range of -40°C to +85°C and draws a maximum supply current of 1.5 mA. Key electrical parameters include a maximum on-resistance of 1.5 kOhms, a maximum turn-on time of 500 ns, and a maximum turn-off time of 500 ns. Power dissipation is rated at 7.5 mW.
Feature Summary
- Supports differential input signals for analog signal routing applications
- Provides high isolation between channels to minimize signal crosstalk
- Designed for surface-mount installation using standard SOIC packaging
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial process control instrumentation
- Medical equipment signal conditioning circuits
Procurement Notes
Verify the specific suffix 'AU' against the manufacturer's official documentation to confirm pinout compatibility and material composition. Ensure that the required operating voltage aligns with the specified dual supply limits. Check humidity sensitivity classification prior to storage and soldering processes to prevent moisture-induced damage during reflow assembly.
Selection Notes
Select this component when a robust 8-channel multiplexer with differential input capability is required. Compare the 1.5 kOhm on-resistance against circuit tolerance requirements. Evaluate the 500 ns switching speed against system timing constraints. Confirm that the SOIC-28 footprint fits the available PCB real estate compared to alternative packages like TSSOP.
Part Context
This part belongs to the MPC507 family of analog multiplexers. It shares functional similarities with other devices in the series but differs in package type and specific electrical tolerances. The AU designation typically indicates a specific tape-and-reel or tube packaging option and temperature grade defined by the manufacturer.
Replacement Considerations
Consult the official cross-reference guide for verified substitutes. Ensure any replacement maintains the 2 x 8:1 configuration and compatible SOIC-28 footprint. Verify that the substitute device meets the same 15 V dual supply requirement and operating temperature range.
