Overview
The NX3L2T384GM,125 is a dual low-ohmic single-pole single-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 two independent switches with bidirectional signal transmission capabilities. The device utilizes an active HIGH enable input (nE) for control. Key electrical parameters include a typical ON resistance of 0.5 Ω at 4.3 V, a -3 dB bandwidth of 60 MHz, and an OFF-state capacitance of 35 pF. It supports continuous current handling up to 350 mA under a 3.3 V supply.
Feature Summary
- Schmitt trigger action at the enable input provides tolerance to slower input rise and fall times.
- Low input voltage threshold allows direct driving by lower level logic signals without requiring translation.
- High noise immunity and robust ESD protection exceeding specified industry standards.
Applications
- Cell phones
- Personal Digital Assistants (PDA)
- Portable media players
Procurement Notes
Verify that the ordering suffix matches the required package type. The GM suffix corresponds to the XQFN8 plastic package. Confirm the temperature range specification aligns with the design requirements before finalizing procurement orders.
Selection Notes
Select this component when a dual SPST analog switch with very low ON resistance is required. Ensure the application voltage stays within the 1.4 V to 4.3 V range. Verify that the control logic levels are compatible with the active HIGH enable inputs provided in the datasheet specifications.
Part Context
This part belongs to the NX3L series of low-voltage analog switches. It shares functional similarities with other devices in the family but is distinct in its dual-channel configuration and specific pinout arrangement for the XQFN8 package.

FAQ
What is the logic state required to turn the switch ON?
The switch is turned ON when the enable input (nE) is set to a HIGH voltage level.
Can the device handle signals with amplitudes up to VCC?
Yes, the NX3L2T384 allows signals with amplitudes up to VCC to be transmitted bidirectionally between the nY and nZ terminals.
What is the maximum operating temperature for this component?
The recommended operating conditions specify a maximum ambient temperature of +125 °C.
