NX3L2G384GM,125

Overview

The NX3L2G384GM,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 active LOW enable input with Schmitt trigger action for noise immunity. The device provides bidirectional signal transmission between two independent terminals per channel. Key electrical parameters include a typical ON resistance of 0.5 Ω at 4.3 V, a maximum OFF-state leakage current of 500 nA, and a -3 dB frequency response of 60 MHz. It supports continuous switch currents up to 350 mA under a 3.3 V supply and is housed in an 8-terminal XQFN package.

Feature Summary

• Dual SPST configuration with bidirectional signal transmission capability
• Active LOW enable inputs with Schmitt trigger action for enhanced noise tolerance
• Low ON resistance ensuring minimal signal attenuation and distortion
• High electrostatic discharge protection across multiple testing standards

Applications

• Cell phones
• Personal digital assistants (PDA)
• Portable media players

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package variant and temperature range. Ensure that the selected component meets the required environmental specifications for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring dual analog switching within a compact footprint. Consider the 1.4 V to 4.3 V operating range and the specific ON resistance characteristics relative to the system's supply voltage. Verify that the control logic levels are compatible with the TTL interface requirements at 3.0 V.

Part Context

This part belongs to the NX3L2G384 family of dual low-ohmic analog switches. The GM suffix specifically denotes the XQFN8 plastic package variant, which measures 1.6 x 1.6 mm. This family is designed for portable electronics where space constraints and power efficiency are critical design factors.

FAQ

How does the enable input function?

The enable input (nE) is active LOW. When the pin is driven HIGH, the analog switch turns off. The input includes Schmitt trigger action to tolerate slower rise and fall times.

What is the maximum continuous switch current?

The device supports a high current handling capability of 350 mA continuous current under a 3.3 V supply.

Does the device support signals above the supply voltage?

Yes, the control input accepts voltages above the supply voltage, and signals with amplitudes up to VCC can be transmitted bidirectionally.
