Overview
The MUX508IDR is a low-capacitance, low-charge injection analog multiplexer manufactured by Texas Instruments. It features an 8:1 single-ended switching configuration housed in a 16-SOIC package. 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 parameters include a maximum on-resistance of 170 Ohms, a channel-to-channel matching of 2.4 Ohms, and a typical off-isolation of -85 dB. Switching times are specified with a maximum turn-on time of 136 ns and a maximum turn-off time of 75 ns. The component supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Low charge injection capability of 0.3 pC for signal integrity
- Rail-to-rail operation across wide power supply ranges
- TTL and CMOS logic compatible digital inputs
- Bidirectional analog channels for flexible signal routing
Applications
- Data acquisition systems requiring high impedance source switching
- Portable instrumentation utilizing low power consumption
- Industrial control systems with varying supply voltages
- Medical equipment needing precise analog signal multiplexing
Procurement Notes
Verify the specific suffix 'IDR' corresponds to the SOIC-16 tape and reel packaging format as documented in official manufacturer datasheets. Confirm that the moisture sensitivity level (MSL 2) requirements align with your assembly line capabilities. Ensure compatibility with standard surface mount technology processes for the narrow SOIC footprint.
Selection Notes
Select the MUX508IDR when an 8:1 single-ended multiplexer is required rather than the differential 4:1 configuration offered by the MUX509 series. Consider this part for designs demanding low charge injection to minimize transient errors in sensitive analog circuits. Verify that the 170 Ohm on-resistance meets the system's voltage drop constraints compared to lower resistance alternatives.
Part Context
The MUX508IDR belongs to the MUX50x family of modern CMOS analog multiplexers from Texas Instruments. This series is designed for applications requiring precision switching with minimal signal distortion. The ID suffix indicates the industrial temperature grade and SOIC package type, while the R suffix denotes the reel packaging method used for automated surface mount assembly.
Replacement Considerations
The MUX508IPWR serves as a pin-compatible alternative in the TSSOP-16 package. For differential 4:1 configurations, the MUX509IDR provides similar electrical characteristics but with a different channel topology.
