Overview
The NX3L1G53GM,125 is a low-ohmic single-pole double-throw analog switch manufactured by NXP Semiconductors. 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 break-before-make switching with an enable input (active LOW) and a digital select input. It supports bidirectional signal transmission between the common port and two independent ports. The component is housed in an XQFN8 package (SOT902-2) and is rated for operation across an ambient temperature range of -40 °C to +125 °C.
Feature Summary
- Low ON resistance ensures minimal attenuation and distortion of transmitted signals
- Break-before-make switching prevents signal overlap during transitions
- Schmitt trigger action at digital inputs provides tolerance to slow rise and fall times
- Control inputs accept voltages above the supply voltage level
Applications
- Cell phones
- Personal Digital Assistants (PDA)
- Portable media players
Procurement Notes
Verify the specific ordering suffix GM, which designates the XQFN8 plastic package variant. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C rating. Ensure the application voltage remains within the 1.4 V to 4.3 V limits to maintain performance specifications.
Selection Notes
Select this component when a compact SPDT analog switch is required for portable electronics. The XQFN8 package offers a small footprint suitable for space-constrained designs. Verify that the system power supply falls within the 1.4 V to 4.3 V operational range and that the load current requirements do not exceed the continuous current handling capability.
Part Context
This part belongs to the NX3L1G53 family of low-ohmic analog switches. Other variants include NX3L1G53GT and NX3L1G53GD, which utilize different XSON8 packages. All variants share identical electrical characteristics and functionality but differ in physical dimensions and terminal configurations.

FAQ
What is the function of the Enable (E) pin?
The Enable pin is active LOW. When the pin is HIGH, the switch is turned off regardless of the Select input state.
How does the device handle slow input signals?
The device incorporates Schmitt trigger action at the digital inputs, making it tolerant to slower input rise and fall times.
What type of switching action is guaranteed?
The device guarantees break-before-make switching to prevent signal overlap between the two output paths.
