NLAS4684MNR2

Overview

The NLAS4684MNR2 is an ultra-low resistance dual single-pole double-throw (SPDT) analog switch manufactured by onsemi. It operates within a supply voltage range of 1.65V to 3.6V, supporting low-voltage digital and analog signal routing. The device features an extremely low on-resistance of 0.1 ohms maximum at VCC = 3.3V, ensuring minimal signal attenuation. Key electrical parameters include a channel-to-channel matching of 0.05 ohms maximum, a break-before-make time of 5 nanoseconds typical, and an off-isolation of 50 decibels at 1 megahertz. It provides high bandwidth with a -3dB frequency of 700 megahertz and includes overvoltage protection up to 3.6 volts beyond the supply rail.

Feature Summary

• Ultra-low on-resistance for minimal signal loss in precision analog paths
• High-speed switching with fast break-before-make timing to prevent signal glitches
• Wide bandwidth suitable for high-frequency data transmission applications
• Integrated overvoltage protection to safeguard internal circuitry from input spikes

Applications

• Portable multimedia devices requiring efficient signal routing
• Automotive infotainment systems for audio and video distribution
• Wireless communication modules for antenna switching
• Medical instrumentation requiring precise analog signal handling

Procurement Notes

Verify the exact suffix 'MNR2' against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives if required for your region. Cross-reference the datasheet revision date to confirm parameter validity. Confirm availability status as legacy or active through authorized distributors. Validate that the operating temperature range meets your specific environmental constraints.

Selection Notes

Select this component when ultra-low insertion loss is critical for signal integrity in low-voltage environments. Compare the 0.1 ohm on-resistance against higher-resistance alternatives to determine power dissipation limits. Consider the 700 MHz bandwidth for high-speed data lines versus lower-frequency requirements. Evaluate the 1.65V minimum supply voltage against system power rails. Assess the small footprint requirements against available board space for the TSSOP-14 package.

Part Context

This device belongs to the NLAS series of analog switches designed for portable and automotive electronics. It complements other low-power switches in the portfolio by offering superior on-resistance characteristics. The series targets applications where signal fidelity and low voltage operation are paramount. It serves as a replacement for older generation switches with higher resistance values.

Replacement Considerations

The NS5A4684SMNTBG is a documented similar part from onsemi with comparable functionality. Verify pinout compatibility before substitution. Check for any differences in thermal performance or package dimensions. Ensure the replacement meets the same voltage and current specifications.
