NX3L1T3157GM,115

Overview

The NX3L1T3157GM,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 input for tolerance to slow rise and fall times. The device supports 1.8 V control logic even when powered at higher voltages up to 4.3 V. It provides very low ON resistance, typically 0.5 Ω at 2.7 V or 4.3 V, with a maximum of 0.9 Ω across the full temperature range. The component handles continuous currents up to 350 mA under a 3.3 V supply. It is housed in an XSON6 (SOT886) package and is specified for operation from -40 °C to +125 °C.

Feature Summary

• Break-before-make switching design prevents signal overlap during transitions.
• High noise immunity and robust ESD protection exceeding 7500 V via HBM standards.
• Capable of transmitting signals with amplitudes up to VCC without requiring level translation.
• CMOS technology ensures low power consumption while maintaining high current handling capability.

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm packaging details. The ,115 designation indicates a reel pack format. Confirm that the selected variant meets the required ambient temperature specifications for the intended application environment before finalizing procurement plans.

Selection Notes

Select this component for applications requiring low signal attenuation and minimal distortion. Ensure the control logic voltage levels are compatible with the device's input thresholds. Verify that the peak ON resistance values align with the system's voltage drop requirements under maximum load conditions.

Part Context
