Overview
The MUX509IWPWR is a dual analog multiplexer switch manufactured by Texas Instruments, featuring two independent 4:1 multiplexer circuits in a single package. It operates with a single supply voltage ranging from 10 V to 36 V or dual supplies of ±5 V to ±18 V. The device offers a maximum on-resistance of 170 Ohms with a channel-to-channel matching of 2.4 Ohms. Switching times are specified at a maximum of 136 ns for turn-on and 75 ns for turn-off. It supports an operating temperature range of -40°C to +125°C and is housed in a 16-TSSOP surface-mount package.
Feature Summary
- Dual 4:1 multiplexer configuration providing two independent signal routing channels within a compact integrated circuit.
- Low charge injection characteristic of 0.3 pC ensures minimal signal distortion during switching operations.
- High off-isolation performance of -96 dB at 1 MHz effectively suppresses crosstalk between active and inactive channels.
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial process control instrumentation
- Medical equipment signal conditioning
Procurement Notes
Verify the specific suffix 'G4' against official Texas Instruments documentation to confirm RoHS compliance status, as manufacturing revisions may alter environmental certifications. Confirm the exact package variant matches the design requirements before procurement, as pinout compatibility depends on the specific housing type.
Selection Notes
Select this component when dual independent 4:1 multiplexing is required within a single footprint. Ensure the application voltage stays within the 10 V to 36 V single supply or ±5 V to ±18 V dual supply limits. Verify that the 170 Ohm on-resistance meets the signal integrity requirements for the specific load conditions.
Part Context
This part belongs to the MUX50x family of analog multiplexers from Texas Instruments. It shares functional similarities with the MUX508 but provides dual-channel capability instead of a single channel. The device is designed for applications requiring high reliability and low power consumption in industrial and medical environments.
Replacement Considerations
The MUX509IDR serves as a pin-compatible alternative in a 16-SOIC package. Verify thermal performance and physical dimensions if substituting into existing PCB layouts, as package width differences may affect clearance requirements.
