NX3L2G384GD,125

Overview

The NX3L2G384GD,125 is a dual low-ohmic single-pole single-throw analog switch manufactured by NXP USA Inc. It operates on a single supply voltage ranging from 1.4 V to 4.3 V and supports an ambient temperature range of -40 °C to +125 °C. The device features Schmitt trigger action at the enable input for tolerance to slow signal transitions. Key electrical parameters include a typical ON resistance of 0.5 Ω at 2.7 V and 4.3 V, with a maximum of 0.9 Ω across the extended temperature range. Enable time ranges from 7 ns to 48 ns depending on voltage, while disable time spans 3 ns to 21 ns. The component handles up to 350 mA continuous current and offers high noise immunity with ESD protection exceeding 7500 V (HBM).

Feature Summary

• Dual SPST configuration with bidirectional signal transmission capability between independent input/output terminals.
• Schmitt trigger enabled inputs provide robustness against slow rise and fall times in control signals.
• High electrostatic discharge protection ratings ensure reliability under harsh handling conditions.
• Control inputs accept voltages above the supply voltage, facilitating direct interface with various logic levels.

Applications

• Cell phone circuitry
• Personal Digital Assistant (PDA) systems
• Portable media player signal routing

Procurement Notes

Verify the specific package variant GD corresponds to the XSON8 plastic extremely thin small outline package with dimensions 3 x 2 x 0.5 mm. Confirm that the ordering suffix indicates the correct temperature grade for operation up to +125 °C. Ensure compatibility with the required PCB footprint for SOT996-2 mounting. Cross-reference the marking code ML2 for identification upon receipt.

Selection Notes

Select this component when a dual-channel analog switch with very low ON resistance is required for portable applications. It is suitable for designs needing high current handling capabilities up to 350 mA. Consider the wide supply voltage range for systems operating between 1.4 V and 4.3 V. Verify that the XSON8 package size fits the available board space constraints.

Part Context

This part belongs to the NX3L2G384 family of dual low-ohmic SPDT analog switches. Other variants in the series include the GT version in an XSON8 package (SOT833-1) and the GM version in an XQFN8 package (SOT902-2). All variants share identical electrical characteristics but differ in physical package dimensions and terminal configurations.
