NX3L1G3157GM,115

Overview

The NX3L1G3157GM,115 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 Schmitt trigger action at the digital select input for tolerance to slow signal transitions. The device provides bidirectional signal transmission between a common port (Z) and two independent ports (Y0, Y1). Typical ON resistance ranges from 0.5 Ω to 1.6 Ω depending on supply voltage. It supports continuous current handling up to 350 mA under a 3.3 V supply. The component is available in an XSON6 package (SOT886) with an operating temperature range of -40 °C to +125 °C.

Feature Summary

• Break-before-make switching mechanism prevents simultaneous connection of both channels
• High noise immunity with Schmitt trigger inputs tolerant to slow rise and fall times
• Robust ESD protection exceeding 7500 V via Human Body Model standards
• Control input accepts voltages above the supply rail without damage

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and temperature rating. Confirm the product status as active or discontinued through authorized distributors before initiating procurement. Ensure compliance with RoHS directives and REACH regulations relevant to the manufacturing region.

Selection Notes

Select this component when a low-resistance analog switch is required for portable electronics. Verify that the application voltage falls within the 1.4 V to 4.3 V range. Consider the XSON6 package dimensions if space constraints are critical. Ensure the control logic levels match the specified VIH and VIL thresholds for the chosen supply voltage.

Part Context

This part belongs to the NX3L1G3157 series of low-ohmic analog switches. It serves as a 2:1 multiplexer or demultiplexer. The GM variant specifically denotes the XSON6 plastic extremely thin small outline package. Other variants in the family may utilize different packages such as SC-88.
