NX3L4684GM,115

Overview

The NX3L4684GM,115 is a dual low-ohmic single-pole double-throw analog switch manufactured by NXP USA Inc. It operates within a supply voltage range of 1.4 V to 4.3 V and supports an ambient temperature range from -40 °C to +125 °C. The device features very low ON resistance, typically 0.25 Ω for the Y0 port at 2.7 V or higher, and 0.5 Ω for the Y1 port at 2.7 V or higher. It includes Schmitt trigger action at digital inputs for noise immunity and allows signals up to VCC to be transmitted bidirectionally. The component is housed in an XQFN10 package (SOT1049-3) with dimensions of 2 x 1.55 x 0.5 mm.

Feature Summary

• Dual SPDT configuration with independent select inputs for each channel
• Very low ON resistance ensuring minimal signal attenuation and distortion
• Schmitt trigger inputs provide tolerance to slow input rise and fall times
• Capable of switching 4.3 V signals using 1.8 V control logic without level translation

Applications

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

Selection Notes

Select this component when designing circuits requiring dual analog switching with low signal loss. Ensure the application voltage does not exceed 4.3 V and that the control logic levels are compatible with the specified VIH/VIL ranges. Consider the thermal derating requirements if operating near the maximum temperature limit of 125 °C.

Part Context

This part belongs to the NX3L series of low-power analog switches from NXP Semiconductors. It is designed for portable applications where power consumption and signal integrity are critical. The GM suffix indicates the XQFN10 package variant, which is distinct from the HVSON10 package available in other versions like the NX3L4684TK.

Replacement Considerations
