Overview
The MUX509IDR is a low-capacitance analog multiplexer manufactured by Texas Instruments, housed in a 16-pin SOIC-Narrow package. It features a 2 x 4:1 configuration with four independent channels. The device operates on a single supply voltage ranging from 10 V to 36 V or dual supplies of ±5 V to ±18 V. Key electrical specifications include a maximum on-resistance of 200 Ohms, a typical off-isolation of -85 dB, and a maximum power supply current of 77 uA. Switching performance is characterized by a maximum turn-on time of 149 ns and a maximum turn-off time of 75 ns. The component supports an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Low capacitance design for high-frequency signal integrity
- Dual supply or single supply operation flexibility
- High off-isolation for effective channel separation
Applications
- Data acquisition systems requiring multi-channel signal routing
- Industrial process control instrumentation
- Medical equipment signal conditioning
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for your target market. Check moisture sensitivity level (MSL) ratings if the part has been exposed to ambient conditions prior to soldering. Ensure the supplier provides valid traceability documentation for quality assurance purposes.
Selection Notes
Select this component when a 2 x 4:1 multiplexer topology is required within a narrow surface-mount footprint. Compare the 200 Ohm on-resistance limit against load requirements to ensure acceptable voltage drop. Evaluate the 77 uA supply current against total system power budgets. Verify that the 10 V minimum operating voltage aligns with available system rails.
Part Context
This part belongs to the MUX509 series of analog multiplexers from Texas Instruments. It shares functional similarities with the MUX508 but differs in channel configuration. The ID suffix indicates a commercial grade variant in a SOIC package. Related parts in the family include the MUX509IPWR in a TSSOP package.
Replacement Considerations
The MUX508IDR offers similar electrical characteristics but provides an 8:1 single-channel configuration instead of the 2 x 4:1 layout. The MUX509IPWR serves as a pin-compatible alternative in a TSSOP-16 package. Verify pinout compatibility before substituting these devices.
