NX3L4051HRZ

Overview

The NX3L4051HRZ is a single low-ohmic 8-channel analog switch manufactured by NXP Semiconductors. It operates within a supply voltage range of 1.4 V to 4.3 V and features an HXQFN16 package (SOT1039-2). The device provides a typical ON resistance of 0.5 Ω at 4.3 V, with a maximum of 0.75 Ω. It supports a continuous current handling capability of up to 350 mA under a 3.3 V supply. The component functions as an analog or digital multiplexer/demultiplexer with three digital select inputs and one common enable input. It exhibits a maximum enable time of 45 ns and a disable time of 25 ns at the upper voltage limit. The operating temperature range extends from -40 °C to +125 °C.

Feature Summary

• Capable of switching signals with amplitudes up to VCC using 1.8 V logic levels without requiring external level translation.
• Features Schmitt trigger action at digital inputs to ensure tolerance for slower input rise and fall times.
• Provides break-before-make switching to prevent signal overlap during channel transitions.
• Includes high electrostatic discharge protection exceeding 7500 V via Human Body Model standards.

Applications

• Cell phone
• PDA
• Portable media player
• Analog multiplexing and demultiplexing
• Digital multiplexing and demultiplexing

Procurement Notes

Verify the specific ordering suffix HRZ corresponds to the HXQFN16 package configuration when sourcing components. Confirm that the procurement documentation references the correct product data sheet revision to ensure alignment with the specified electrical characteristics and thermal dissipation limits for the target application environment.

Selection Notes

Select this component for designs requiring bidirectional signal transmission between a common port and eight independent ports. Ensure the control logic voltage aligns with the 1.8 V threshold compatibility for efficient operation in 3.3 V systems. Verify that the required ON resistance and leakage current specifications meet the signal integrity requirements of the intended analog or digital path.

Part Context

This part belongs to the NX3L4051 series of single low-ohmic 8-channel analog switches. It shares functional similarities with the NX3L4051PW variant but utilizes a distinct HXQFN16 package instead of TSSOP16. Both variants offer identical electrical performance metrics while differing in physical footprint and thermal power dissipation capabilities.
