NX3L1T3157GMZ

Overview

The NX3L1T3157GMZ is a low-ohmic single-pole double-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 features a maximum ON resistance of 0.75 Ω at 25 °C, increasing to 0.9 Ω across the industrial temperature range of -40 °C to +125 °C. The device provides high current handling capability with a continuous current rating of 350 mA under a 3.3 V supply. It utilizes an XSON6 (SOT886) package for surface mount installation.

Feature Summary

• Schmitt trigger action at the digital input ensures tolerance to slower signal rise and fall times.
• Low threshold logic allows control by 1.8 V levels while switching signals up to 4.3 V without level translation.
• Break-before-make switching mechanism prevents signal overlap during transitions.
• Robust ESD protection meets HBM Class 3A and IEC61000-4-2 contact discharge standards.

Applications

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

Procurement Notes

Verify the specific ordering suffix GMZ against the manufacturer's latest documentation to confirm packaging details. This variant utilizes a Static Shielding Bag (SSB) solution rather than standard reel packing. Ensure compatibility with the specified SSB storage requirements between uses to maintain component integrity during procurement and handling.

Selection Notes

Select this component when designing circuits requiring low signal attenuation and minimal distortion in portable electronics. The wide supply voltage range supports operation in battery-powered devices. Verify that the application environment remains within the specified -40 °C to +125 °C operating temperature limits to ensure performance stability.
