NX3L1T53GD,125

Overview

The NX3L1T53GD,125 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 inputs for noise immunity. The device provides a typical ON resistance of 0.5 Ω at 4.3 V and supports continuous currents up to 350 mA. It includes an active LOW enable input and break-before-make switching capability. The component is housed in an XSON8 package (SOT996-2) with dimensions of 3 x 2 x 0.5 mm and is rated for operation between -40 °C and +125 °C.

Feature Summary

• Low ON resistance ensures minimal signal attenuation and distortion across the operating voltage range.
• Schmitt trigger action at digital inputs provides high noise immunity and tolerance for slow input transitions.
• Break-before-make switching prevents signal overlap during channel transitions.
• Robust ESD protection meets HBM Class 3A standards exceeding 7500 V.

Applications

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

Procurement Notes

Verify the specific ordering suffix GD against the manufacturer's current documentation to confirm the XSON8 package variant. Ensure that design parameters align with the recommended operating conditions specified in the official datasheet. Confirm compliance with RoHS directives and check for any recent revision updates before finalizing procurement specifications.

Selection Notes

Select this component when a single SPDT switch with low ON resistance is required for portable applications. It is suitable for signals up to VCC amplitude controlled by 1.8 V logic levels without level translation. Verify that the thermal dissipation requirements fit within the 250 mW limit for the specified temperature range.

Part Context
