NX3L1T384GM,115

Overview

The NX3L1T384GM,115 is a low-ohmic single-pole single-throw analog switch manufactured by NXP USA Inc. It operates within a supply voltage range of 1.4 V to 4.3 V and features an active LOW enable input (E). The device supports bidirectional signal transmission between terminals Y and Z with amplitudes up to VCC. Key electrical parameters include a typical ON resistance of 0.5 Ω at VCC = 2.7 V and 4.3 V, and a flatness of 0.13 Ω at 2.7 V. It offers high noise immunity with ESD protection exceeding 7500 V (HBM) and 4000 V (IEC61000-4-2 contact discharge). The component is housed in an XSON6 package (SOT886) and is specified for operation from -40 °C to +125 °C.

Feature Summary

• Ultra-low ON resistance ensures minimal signal attenuation and distortion across the operating voltage range.
• Schmitt trigger action on the enable input provides tolerance to slow input rise and fall times.
• Capable of switching signals up to VCC using lower-level logic control without requiring level translation.
• High current handling capability allows continuous current flow under standard supply conditions.

Applications

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

Procurement Notes

FAQ

How does the enable input function?

The enable input (E) is active LOW. When E is HIGH, the analog switch is turned off. Schmitt trigger action at this input makes the circuit tolerant to slower input rise and fall times.

What is the maximum signal amplitude supported?

The NX3L1T384 allows signals with an amplitude up to VCC to be transmitted from terminal Y to Z or from Z to Y.

Is the switch bidirectional?

Yes, the switch is bidirectional, allowing signals to be transmitted from Y to Z or from Z to Y.
