MAX4742EUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4742EUA is a dual single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single supply voltage ranging from 2.7V to 5.5V. The device features an on-resistance of 0.8 ohms and supports a continuous current of 100mA. It includes a shutdown mode with low power consumption. The IC is housed in an 8-pin uMAX or uSOP package, suitable for surface-mount applications.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPST configuration for independent signal routing
• Low on-resistance for minimal signal attenuation
• Single-supply operation compatible with standard logic levels
• Shutdown mode reduces power consumption during idle states

Analog Switches, Multiplexers, Demultiplexers Applications

• Instrumentation signal path control

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix (e.g., +T for tape and reel) against your manufacturing requirements. Confirm RoHS compliance status through official documentation. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet for pinout compatibility with existing PCB layouts. Validate supply chain authenticity through authorized distributors.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Consider the 0.8 ohm on-resistance for low-loss applications. Evaluate the 100mA current capability against load requirements. Check the 2.7V minimum supply voltage for compatibility with your power rails. Assess the uMAX/uSOP package size for space constraints. Review the shutdown current if power efficiency is critical.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX474x family of low-voltage analog switches. It shares functional similarities with other dual SPST devices but offers specific performance characteristics like 0.8 ohm resistance. The uMAX package provides a compact footprint compared to larger SOIC options. It is designed for portable and battery-powered applications requiring efficient signal management.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4742EUA+ is the lead-free version of this component. Verify pin-for-pin compatibility with alternative dual SPST switches from the same manufacturer. Check if higher-speed or lower-resistance variants are needed for specific signal integrity requirements.
