Product details
Overview
NX3L1G66GM,115 from NXP Semiconductors is a low-ohmic single-pole single-throw (SPST) analog switch in XSON6 package, operating from 1.4 V to 4.3 V supply. It features 0.50 Ω typical ON resistance at 2.7 V and 4.3 V, Schmitt-trigger enable input (E), and bidirectional signal routing between Y and Z terminals. It supports portable audio routing in battery-powered consumer devices.
For engineers reviewing the NX3L1G66GM,115 datasheet, NX3L1G66GM,115 pinout, NX3L1G66GM,115 application, or NX3L1G66GM,115 equivalent, key selection criteria include ON-resistance flatness (0.13 Ω), −40 °C to +125 °C operation, ESD robustness (4 kV IEC61000-4-2 contact), and 350 mA continuous switch current capability.
Technical Context
The NX3L1G66GM,115 implements a CMOS transmission gate architecture with Schmitt-trigger action on the active-HIGH enable pin (E), enabling tolerance to slow input edges. Its bidirectional Y–Z path supports analog signals up to VCC amplitude without level-shifting.
Static performance is characterized across −40 °C to +125 °C, with ON-state leakage ≤500 nA and OFF-state leakage ≤50 nA at 125 °C. Dynamic metrics include 14 ns typical enable time (VCC = 3.6 V) and −90 dB isolation at 100 kHz in OFF-state.

FAQ
What is the maximum continuous current rating for the NX3L1G66GM,115?
The NX3L1G66GM,115 supports ±350 mA continuous current through its Y–Z switch path when supplied at 3.3 V. This rating is validated across the full −40 °C to +125 °C operating range and enables reliable use in headphone driver circuits and sensor multiplexers without thermal derating under typical conditions.
Does the NX3L1G66GM,115 require external pull-up or pull-down resistors on the enable pin?
No, the NX3L1G66GM,115 does not require external pull-up or pull-down resistors on the enable (E) pin. Its integrated Schmitt-trigger input provides defined logic thresholds and hysteresis, ensuring stable operation even with slow or noisy control signals-eliminating the need for external biasing components in most portable designs.
Can the NX3L1G66GM,115 operate with a 1.4 V supply voltage?
Yes, the NX3L1G66GM,115 is fully specified down to 1.4 V supply voltage. At this rail, it delivers 1.6 Ω typical ON resistance and maintains functional integrity across −40 °C to +125 °C, making it suitable for ultra-low-power applications powered by single-cell LiFePO₄ or regulated 1.4–1.8 V domains.
What is the OFF-state isolation performance of the NX3L1G66GM,115?
The NX3L1G66GM,115 provides −90 dB typical isolation between Y and Z terminals in the OFF state at 100 kHz. This high isolation is maintained across the full 1.4 V to 4.3 V supply range and ensures minimal crosstalk in multi-channel audio or sensor routing applications where signal integrity is critical.
Is the NX3L1G66GM,115 pin-compatible with other members of the NX3L family?
No, the NX3L1G66GM,115 in XSON6 (SOT886) is not pin-compatible with the NX3L1G66GW in TSSOP5 (SOT353-1). While both share identical functionality and electrical specs, their pinouts differ: the XSON6 includes a dedicated n.c. terminal (pin 5), whereas the TSSOP5 places GND at pin 3 and omits n.c. Pin mapping must be verified per package drawing before PCB reuse.
