Overview
The MPC508AU/1K is an analog multiplexer switch integrated circuit manufactured by Texas Instruments. It features a single-ended input configuration with eight channels arranged in a 1 x 8:1 topology. The device operates on a dual supply voltage of ±15 V, with a maximum operating voltage of 18 V. Key electrical parameters include a maximum on-resistance of 1.5 kOhms, a maximum power dissipation of 7.5 mW, and a maximum supply current of 1.5 mA. Switching performance is defined by a maximum turn-on time and turn-off time of 500 ns each. The component is housed in a 16-lead SOIC package and supports surface-mount installation. It functions within a commercial temperature range from -40°C to +85°C.
Feature Summary
- Provides eight-channel signal routing via a single-ended input architecture
- Supports dual supply operation for flexible system integration
- Delivers consistent switching timing with matched turn-on and turn-off durations
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial control circuits utilizing analog signal multiplexing
- Test and measurement equipment involving signal path switching
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure that the procurement channel provides valid traceability for humidity-sensitive devices. Confirm RoHS compliance status through the latest datasheet revision before finalizing purchase orders.
Selection Notes
Select this component when an eight-channel single-ended multiplexer is required within a 16-pin surface-mount footprint. Compare the 1.5 kOhm on-resistance against application requirements to ensure acceptable signal attenuation. Verify that the ±15 V dual supply capability aligns with the target system's power distribution network.
Part Context
This part belongs to the MPC508 series of analog multiplexers produced by Texas Instruments. It serves as a specialized solution for routing multiple analog signals to a common output line. The device complements other members of the family, such as differential variants or different channel counts, offering a focused option for single-ended applications.
Replacement Considerations
Direct replacements within the same series include the MPC508AU without the reel suffix for tube packaging verification. Cross-series alternatives may include the MUX508IPWRG4, though differences in on-state capacitance and package type require careful evaluation.
