Overview
The MUX509IPWR is a dual 4:1 analog multiplexer switch IC manufactured by Texas Instruments, housed in a 16-TSSOP surface-mount 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. The device features a typical turn-on time of 136ns and turn-off time of 75ns, with a maximum power supply current of 77uA. Operating temperatures range from -40°C to +125°C.
Feature Summary
- Dual independent 4:1 multiplexing channels for signal routing
- Low on-resistance with tight channel-to-channel matching
- Wide single and dual power supply voltage compatibility
- High off-isolation performance for signal integrity
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial process control instrumentation
- Medical equipment signal conditioning circuits
Procurement Notes
Verify the specific ordering suffix IPWR against the manufacturer's official datasheet to confirm the TSSOP-16 package and tape-and-reel packaging configuration. Ensure compliance with RoHS3 standards and moisture sensitivity level 2 requirements during storage and handling procedures.
Selection Notes
Select this component when dual isolated 4:1 switching is required within a compact surface-mount footprint. Compare the 170 Ohm on-resistance against system loss tolerances and verify that the 10V minimum single-supply requirement aligns with available power rails.
Part Context
This part belongs to the MUX50x family of analog multiplexers designed for precision switching applications. It complements other variants like the MUX509ID which offers similar functionality in different packaging configurations such as SOIC-Narrow-16.
Replacement Considerations
The MUX509ID serves as a functional alternative offering identical switching specifications but utilizes an SOIC-Narrow-16 package instead of TSSOP-16.
