Overview
The MPC509AU/1K is an analog multiplexer switch IC from the Texas Instruments MPC509 series, housed in a 16-pin SOIC package. It features a 2 x 4:1 configuration with four channels supporting differential inputs. 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 of 500 ns and a maximum turn-off time of 500 ns. The component is rated for an industrial temperature range from -40°C to +85°C.
Feature Summary
- Supports differential input configurations for two independent 4-to-1 multiplexing paths.
- Designed for operation with dual power supplies up to ±15 V.
- Provides high isolation characteristics suitable for precision signal routing applications.
Applications
- Data acquisition systems requiring multi-channel signal selection.
- Industrial process control instrumentation.
- Test and measurement equipment involving analog signal switching.
Procurement Notes
Verify the specific suffix '1K' against the official Texas Instruments datasheet to confirm packaging details and moisture sensitivity level. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability before finalizing orders.
Selection Notes
Select this component when a 2 x 4:1 multiplexer with differential input capability is required. The ±15 V dual supply specification distinguishes it from single-supply alternatives like the MUX509. Consider the 1.5 kOhm on-resistance limit for signal integrity requirements. The SOIC-16 package is suitable for surface-mount assembly processes within the specified industrial temperature range.
Part Context
The MPC509AU/1K belongs to the MPC509 family of analog multiplexers. It shares similar switching speeds and power specifications with other members such as the MPC508AU/1K and MPC507AU/1K. The primary distinction lies in its channel count and input type; unlike the single-ended MPC508 or the 8-channel MPC507, this part offers four channels with differential input support in a compact 16-pin form factor.
Replacement Considerations
The MUX509IDR is a functional substitute offering similar 2 x 4:1 topology but with lower on-resistance (200 Ohms) and broader voltage ranges. Verify pin compatibility and thermal performance differences when substituting the MPC509AU/1K with higher-performance variants.
