NX3L4684TK,132

Overview

The NX3L4684TK,132 is a dual low-ohmic single-pole double-throw analog switch manufactured by NXP USA Inc. It operates within a supply voltage range of 1.4 V to 4.3 V and supports bidirectional signal transmission up to the VCC level. The device features very low ON resistance, typically 0.3 Ω for the Y0 port and 0.5 Ω for the Y1 port at 2.3 V supply. It includes Schmitt trigger inputs tolerant to slow rise/fall times and allows 1.8 V logic control at higher supply voltages. The component provides high noise immunity, break-before-make switching, and robust ESD protection exceeding 4000 V (HBM). It is housed in an HVSON10 package (SOT650-2) with a temperature range of -40 °C to +125 °C.

Feature Summary

• Dual SPDT analog switches with extremely low ON resistance for minimal signal attenuation
• Capable of handling signals up to VCC while controlled by lower voltage logic levels
• Integrated Schmitt triggers ensure tolerance to slow input transition rates
• High electrostatic discharge protection across multiple testing standards

Applications

• Cell phones
• Personal Digital Assistants (PDA)
• Portable media players

Procurement Notes

Verify the specific ordering suffix TK corresponds to the HVSON10 package (SOT650-2) as defined in the official documentation. Confirm that the required operating temperature range aligns with the -40 °C to +125 °C specification provided for this variant. Ensure design compatibility with the 1.4 V to 4.3 V supply voltage limits before finalizing procurement.

Selection Notes

Select this component when low signal distortion is critical due to its sub-ohm ON resistance characteristics. It is suitable for applications requiring direct interfacing between 1.8 V logic controllers and higher voltage analog signals without external level shifters. Consider the HVSON10 package dimensions if board space is constrained. Verify that the continuous current handling capability meets the specific load requirements of the target circuit.

Part Context

This part belongs to the NX3L series of low-ohmic analog switches from NXP Semiconductors. The 'TK' suffix specifically identifies the HVSON10 plastic thermal enhanced very thin small outline package variant. This distinguishes it from other package options like the XQFN10 found in the GM suffix version, ensuring physical footprint compatibility during design implementation.

Replacement Considerations

The NX3L4684GM serves as a pin-compatible alternative offering identical electrical performance but utilizes an XQFN10 package instead of the HVSON10 form factor.
