Overview
The NX3L2G384GT,115 is a dual low-ohmic single-pole single-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 Schmitt trigger action at the active LOW enable input for tolerance to slower signal transitions. Typical ON resistance values range from 1.6 Ω at 1.4 V to 0.5 Ω at voltages of 2.7 V and above. Dynamic characteristics include enable times up to 48 ns and disable times up to 21 ns depending on the supply voltage. The component is housed in an XSON8 package (SOT833-1) with dimensions of 1 x 1.95 x 0.5 mm.
Feature Summary
- Dual SPST analog switches with bidirectional signal transmission capabilities
- Schmitt trigger enabled control inputs for improved noise immunity
- High electrostatic discharge protection exceeding specified thresholds for HBM, MM, CDM, and IEC contact discharge
- Low power CMOS consumption with latch-up performance exceeding standard limits
Applications
- Cell phones
- Personal digital assistants
- Portable media players
Procurement Notes
Verify the ordering suffix GT corresponds to the XSON8 SOT833-1 package variant. Confirm the specific temperature grade matches the design requirements, as the base part number covers both -40°C to +85°C and -40°C to +125°C ranges. Ensure the datasheet revision aligns with current manufacturing specifications before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring low ON resistance and high current handling up to 350 mA continuous under 3.3 V supply. The wide supply voltage compatibility allows direct interfacing with TTL levels at 3.0 V. Consider the XSON8 package constraints regarding thermal dissipation and board space limitations during layout planning.
Part Context
This part belongs to the NX3L2G384 family of dual low-ohmic analog switches. Other variants in the series include the NX3L2G384GD in an XSON8 package and the NX3L2G384GM in an XQFN8 package. All variants share identical electrical characteristics but differ in physical footprint and terminal configuration.

FAQ
What is the function of the enable input?
The enable input (nE) is active LOW. When nE is HIGH, the analog switch is turned off. Schmitt trigger action at this input provides tolerance to slower input rise and fall times.
How does the device handle signals relative to the supply voltage?
The NX3L2G384 allows signals with amplitude up to VCC to be transmitted bidirectionally between the nY and nZ terminals.
What are the ESD protection ratings?
The device offers HBM protection exceeding 7500 V, MM protection exceeding 200 V, CDM protection exceeding 1000 V, and IEC61000-4-2 contact discharge protection exceeding 4000 V for switch ports.
