Overview
The NX3L1G384GW,125 is a 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 bidirectional signal transmission between terminals Y and Z. The device includes an active LOW enable input (E) with Schmitt trigger action for noise immunity. Key electrical parameters include a peak ON resistance of 0.5 Ω at 2.7 V and 4.3 V, and a typical OFF-state leakage current of ±5 nA at 25 °C. Dynamic characteristics specify a maximum enable time of 24 ns at higher voltages and a -3 dB bandwidth of 60 MHz. The component supports continuous switch currents up to 350 mA under a 3.3 V supply.
Feature Summary
- Bidirectional signal transmission capability allowing data flow in either direction between independent input/output terminals.
- Active LOW enable control with Schmitt trigger functionality to ensure tolerance against slow input rise and fall times.
- High electrostatic discharge protection exceeding specified thresholds for Human Body Model, Machine Model, and Charged Device Model standards.
Applications
- Cell phone
- PDA
- Portable media player
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and temperature range specifications. Ensure that the selected variant matches the required thermal performance and physical footprint for the target design. Cross-reference the part number with official distributor catalogs to validate current product status and availability constraints before finalizing procurement plans.
Selection Notes
Select this component when designing circuits requiring low ON resistance and high current handling within a compact form factor. Consider the 1.4 V to 4.3 V operating range to ensure compatibility with the system power rails. Evaluate the package dimensions and pin configuration to verify mechanical fit within the intended PCB layout constraints.
Part Context
This component belongs to the NX3L1G384 series of low-ohmic analog switches produced by NXP Semiconductors. The series is designed for portable electronic applications where space efficiency and signal integrity are critical. The specific model utilizes an XSON6 plastic extremely thin small outline package, providing a minimal footprint suitable for dense circuit board arrangements.
Replacement Considerations
The NX3L1G384GM is listed as a related variant within the same family. Verify pinout compatibility and electrical parameter equivalence before substitution. Consult the official datasheet revision history for any discontinued packages or updated ordering information.
