NX3V1T384GM,115

Overview

The NX3V1T384GM,115 is a single-pole double-throw (SPDT) analog switch manufactured by NXP Semiconductors. It operates within a supply voltage range of 1.4 V to 4.3 V and features an ultra-low on-resistance of typically 0.25 Ω at 4.3 V. The device supports bidirectional signal transmission with amplitudes up to the supply voltage. It includes Schmitt trigger action at the enable input for noise immunity and offers high ESD protection exceeding 7500 V via HBM. The component is available in an 8-XQFNU package measuring 1.6x1.6 mm and is specified for operation from -40 °C to +125 °C.

Feature Summary

• Ultra-low on-resistance ensures minimal signal attenuation and distortion during transmission.
• Bidirectional switching capability allows signals to pass between terminals Y and Z regardless of direction.
• Schmitt trigger enable input provides tolerance to slow input rise and fall times.

Applications

• Portable consumer electronics requiring low power consumption
• Battery-powered systems utilizing USB or similar interfaces
• Signal routing in compact mobile devices

Procurement Notes

Verify the specific ordering suffix against official NXP documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and REACH regulations as stated in the manufacturer's environmental declarations. Confirm availability status directly with authorized distributors, as production lifecycles may change without prior notice.

Selection Notes

Select this component when designing circuits that require low insertion loss and high-speed switching within a small footprint. The wide supply voltage range accommodates various logic levels, while the robust ESD protection safeguards sensitive downstream components. Verify that the thermal performance meets the requirements for the intended operating temperature range.

Part Context

This part belongs to the NX3V series of low-ohmic analog switches designed for portable applications. It shares functional similarities with other members like the NX3V1G384 but differs in configuration and pinout. The series emphasizes low power consumption and high current handling capabilities suitable for modern mobile and battery-operated devices.

Replacement Considerations

Check for direct pin-compatible alternatives within the NX3V family, such as the NX3V1G384, ensuring electrical parameters match the design requirements. Verify package dimensions and thermal characteristics before substitution to maintain board layout integrity.
