Product details
Overview
NX3L1G66GM,132 from NXP Semiconductors is a low-ohmic SPST analog switch in XSON6 package, operating from 1.4 V to 4.3 V supply, with 0.5 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 devices requiring minimal signal distortion and high noise immunity.
For engineers reviewing the NX3L1G66GM,132 datasheet, NX3L1G66GM,132 pinout, NX3L1G66GM,132 application, or NX3L1G66GM,132 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 under 3.3 V supply.
Technical Context
The NX3L1G66GM,132 implements a CMOS transmission gate architecture with Schmitt-trigger action on the active-HIGH enable (E) pin, enabling reliable switching despite slow-rising control signals. Its bidirectional Y–Z path supports analog signal amplitudes up to VCC without level-shifting.
Static performance is specified across −40 °C to +125 °C, with ON-state leakage ≤500 nA and OFF-state leakage ≤500 nA at full temperature range. Dynamic behavior includes enable time as low as 14 ns (VCC = 2.7–4.3 V) and disable time down to 4 ns, supporting high-speed signal gating in portable interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 4.3 V - Enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 4.2 V Li-ion battery rails without level shifters. |
| ON Resistance (Typical) | 0.50 Ω at VCC = 2.7 V and 4.3 V - Ensures <0.1% signal attenuation for 100 mA audio or sensor signals. |
| ON Resistance Flatness | 0.13 Ω at VCC = 2.7 V - Minimizes harmonic distortion (<0.02% THD) in audio-frequency paths. |
| Switch Current Rating | ±350 mA continuous - Supports high-drive headphone amplifiers or sensor excitation circuits. |
| ESD Robustness | 4 kV IEC61000-4-2 contact discharge on switch ports - Eliminates need for external TVS diodes in handheld ESD-prone environments. |
| Operating Temperature | −40 °C to +125 °C - Qualified for extended industrial and automotive cabin-adjacent applications. |
| Enable Propagation Delay | 14 ns max (VCC ≥ 2.7 V) - Allows clean gating of digital control signals in sub-50 ns timing windows. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Y) | Switch terminal A | Bidirectional analog I/O; connects to source or load depending on system topology; accepts signals up to VCC. |
| 2 (Z) | Switch terminal B | Bidirectional analog I/O; functionally identical to Y; enables flexible PCB layout with symmetric routing. |
| 3 (GND) | Ground reference | Primary return path for switch current and internal logic; must be low-impedance for THD and crosstalk control. |
| 4 (E) | Enable input | Active-HIGH Schmitt-trigger control; tolerates slow edges; VIH/VIL thresholds scale with VCC per JEDEC JESD8-12. |
| 5 (n.c.) | No-connect | Internally unconnected; left floating on PCB; no soldering or routing required. |
| 6 (VCC) | Power supply | Single-supply rail powering both analog switch core and digital control logic; decoupling capacitor mandatory. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DCUR | 0.9 Ω typical RON at 3.3 V; 6-pin VSSOP; no Schmitt trigger on EN; 1.65–5.5 V supply. | Lacks Schmitt-trigger enable; higher RON increases THD in audio paths; wider supply but less optimized for 1.8 V systems. | Prefer NX3L1G66GM,132 when Schmitt-trigger noise immunity or sub-1 Ω RON at 1.8–2.7 V is required. |
| ADG801BRMZ-REEL7 | 0.3 Ω typical RON at 3 V; 6-pin SOT-23; no Schmitt trigger; −40 °C to +125 °C; 1.8–5.5 V supply. | Lower RON but lacks ESD robustness (2 kV HBM only); no IEC61000-4-2 rating; higher cost and longer lead time. | Choose NX3L1G66GM,132 for production-ready ESD-hardened designs where 4 kV contact discharge is mandated. |

FAQ
What is the maximum continuous current rating for the NX3L1G66GM,132?
The NX3L1G66GM,132 supports ±350 mA continuous current through its Y–Z switch path when supplied at 3.3 V, as specified in Table 5 (Limiting Values) of the official NXP datasheet Rev. 8. This rating applies across the full −40 °C to +125 °C operating range and assumes adequate PCB copper area for thermal dissipation. Peak pulsed current reaches ±500 mA at 1 ms/10% duty cycle.
Does the NX3L1G66GM,132 support bidirectional analog signal routing?
Yes, the NX3L1G66GM,132 is a fully bidirectional SPST analog switch: signals may pass from Y to Z or Z to Y with identical electrical characteristics-including 0.5 Ω typical ON resistance, 0.13 Ω flatness, and matched THD performance. Its CMOS transmission gate structure imposes no polarity constraints, enabling flexible PCB layout in audio, sensor, and data acquisition paths.
What ESD protection levels does the NX3L1G66GM,132 provide on its switch terminals?
The NX3L1G66GM,132 provides 4000 V IEC61000-4-2 contact discharge ESD protection on both Y and Z switch ports, as confirmed in Section 2 (Features and benefits) and Table 5 of the NXP datasheet. This eliminates the need for external TVS diodes in handheld consumer applications such as smartphones and portable media players where user-accessible connectors are present.
Is the enable input (E) of the NX3L1G66GM,132 compatible with TTL logic levels?
Yes, the enable input (E) of the NX3L1G66GM,132 accepts TTL-compatible voltage levels at 3.0 V supply, as explicitly stated in Section 2. The Schmitt-trigger design ensures noise immunity, and VIH/VIL thresholds scale with VCC per JEDEC JESD8-12-enabling direct interfacing with 3.3 V microcontrollers and baseband processors without level-shifting circuitry.
What is the thermal package type and footprint size of the NX3L1G66GM,132?
The NX3L1G66GM,132 uses the XSON6 (SOT886) package: a leadless, extremely thin small outline package measuring 1.0 mm × 1.45 mm × 0.5 mm with six terminals. Pin 1 is marked by an index area in the lower-left corner.
