Overview
The MUX509IPW is a dual 4:1 analog multiplexer switch IC manufactured by Texas Instruments, housed in a 16-pin TSSOP package. It supports single supply voltages from 10V to 36V or dual supplies of ±5V to ±18V. Key electrical parameters include 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 136ns for turn-on and 75ns for turn-off. The device operates within a temperature range of -40°C to +125°C.
Feature Summary
- Dual independent 4:1 multiplexing channels integrated into a single compact surface-mount package.
- High voltage tolerance capability supporting wide single and dual power supply ranges for flexible system integration.
- Low on-resistance characteristics ensure minimal signal attenuation across the switching path.
Applications
- Data acquisition systems requiring multi-channel signal routing
- Industrial process control instrumentation
- Medical equipment signal conditioning
Procurement Notes
Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and thermal specifications. Ensure the procurement source provides valid RoHS compliance certificates and moisture sensitivity level ratings prior to ordering.
Selection Notes
Select this component when dual isolated 4:1 switching is required within a limited board area. Compare the 170-ohm on-resistance against application signal integrity requirements. Verify that the 16-TSSOP footprint aligns with existing PCB layout constraints and thermal dissipation needs.
Part Context
This part belongs to the MUX50x family of analog multiplexers designed for precision switching applications. It serves as a solution for routing multiple analog signals to a single converter or amplifier stage while maintaining signal fidelity.
Replacement Considerations
Consult the official datasheet for direct pin-compatible alternatives within the same product family. Verify functional equivalence regarding on-resistance and supply voltage ranges before substituting.
