Overview
The MPC508AU is an analog multiplexer switch integrated circuit manufactured by Texas Instruments. It features eight single-ended inputs configured as a single 8:1 channel. The device operates with a dual supply voltage of ±15 V and supports a maximum operating voltage of 18 V. 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. The power dissipation is rated at 7.5 mW, with a maximum supply current of 1.5 mA. It functions within a temperature range of -40°C to +85°C and is housed in a 28-pin SOIC package.
Feature Summary
- Provides eight single-ended analog input channels for signal routing
- Operates on dual power supplies up to ±15 V
- Housed in a surface-mount 28-lead SOIC package
Applications
- Data acquisition systems requiring analog signal selection
- Industrial process control instrumentation
- Test and measurement equipment
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm packaging configuration. Ensure that the procurement source provides valid traceability data consistent with Texas Instruments standards. Confirm RoHS compliance status through the official datasheet before finalizing orders.
Selection Notes
Select this component when eight single-ended analog signals require switching within a dual-supply environment. Compare the 1.5 kOhm on-resistance specification against system requirements to ensure acceptable signal integrity. Verify that the 28-pin SOIC footprint aligns with the target PCB layout constraints.
Part Context
This part belongs to the MPC50x series of analog multiplexers from Texas Instruments. The series includes variants such as the MPC506AU with sixteen single-ended channels and the MPC507AU with differential inputs. The MPC508AU specifically addresses applications needing eight single-ended channels in a standard industrial temperature range.
Replacement Considerations
The MPC507AU serves as a functional alternative for differential input configurations. The MPC506AU offers increased capacity with sixteen single-ended channels. Verify pin compatibility and electrical specifications before substituting these parts.
