Overview
The NX3L2T66GD,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 an ON resistance of 0.5 Ω typical at VCC = 2.7 V. The device includes Schmitt trigger action at the enable input for noise immunity and supports control logic voltages as low as 1.8 V even when powered at higher levels. It provides bidirectional signal transmission with high current handling capability up to 350 mA continuous current under a 3.3 V supply.
Feature Summary
- Dual SPST analog switches with bidirectional signal transmission capabilities
- Schmitt trigger enable inputs providing tolerance to slow input rise and fall times
- High ESD protection exceeding 7500 V HBM and 4000 V IEC61000-4-2 contact discharge
- Low power consumption with very low OFF-state leakage current
Applications
- Cell phones
- Personal Digital Assistants (PDA)
- Portable media players
Procurement Notes
Verify the specific ordering suffix GD against official documentation, as revision history indicates package options may change. Confirm availability status directly with the manufacturer or authorized distributors, as component lifecycle stages can shift between active production and obsolescence without immediate public notice.
Selection Notes
Select this component for applications requiring low ON resistance and flatness to minimize signal attenuation. Ensure the control logic voltage aligns with the specified VIH/VIL thresholds relative to the system supply voltage. Verify that the operating temperature range meets the environmental requirements of the target application.
Part Context
This part belongs to the NX3L2T66 family of dual low-ohmic analog switches. The datasheet revision history notes that the GD package option was removed in version 7.1 released in August 2020. Earlier versions of the document included this package configuration, indicating it may be a legacy or discontinued variant within the product line.

FAQ
Can the NX3L2T66 switch signals with amplitudes up to VCC?
Yes, the device allows signals with amplitude up to VCC to be transmitted bidirectionally between the nY and nZ terminals.
What is the maximum ESD protection rating for Human Body Model (HBM)?
The ESD protection exceeds 7500 V according to JESD22-A114F Class 3A standards.
Does the enable input require level translation if driven by lower level logic?
No, the low input voltage threshold allows the enable pin to be driven by lower level logic signals, such as 1.8 V, without significant increase in supply current, eliminating the need for logic level translation.
