NX3L4051PW,118

Overview

The NX3L4051PW,118 is a single low-ohmic 8-channel analog switch manufactured by NXP Semiconductors. It operates on a single supply voltage ranging from 1.4 V to 4.3 V and features three digital select inputs (S1 to S3) and an active LOW enable input (E). The device provides eight independent inputs/outputs (Y0 to Y7) and one common input/output (Z). It utilizes Schmitt trigger action at the digital inputs for tolerance to slow rise and fall times. The component supports 1.8 V logic levels in 3.3 V applications without significant supply current increase. It offers very low ON resistance, typically 0.5 Ω at 2.7 V and 4.3 V, with high noise immunity and ESD protection exceeding 7500 V HBM.

Feature Summary

• Very low ON resistance ensures minimal signal attenuation and distortion across the operating voltage range.
• Schmitt trigger inputs provide tolerance to slower input rise and fall times while maintaining low power consumption.
• Capable of switching signals up to VCC using a 1.8 V digital controller, eliminating the need for external logic level translation.
• High ESD protection performance meets rigorous standards including HBM Class 3A and IEC61000-4-2 contact discharge.

Applications

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

Procurement Notes

Verify the ordering part number NX3L4051PW,118 against the manufacturer's official documentation to ensure compatibility with the TSSOP16 package. Confirm that the required temperature range of -40 °C to +125 °C aligns with the specific application environment. Check for any recent revision updates or obsolescence notices directly from NXP Semiconductors before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring low-voltage operation between 1.4 V and 4.3 V with minimal signal loss. It is suitable for applications where 1.8 V logic controllers must interface with higher voltage analog signals without additional translation circuitry. Ensure the design accounts for the specified ON resistance variations across different supply voltages and temperatures to maintain signal integrity.

Part Context

This part belongs to the NX3L4051 series of single low-ohmic 8-channel analog switches. It is functionally compatible with other SP8T analog switches but is distinguished by its optimized low-voltage performance and specific ESD protection ratings. The PW suffix indicates the TSSOP16 plastic thin shrink small outline package variant, designed for surface mount applications.
