Product details
Overview
NX3L1G66GW-Q100 from NXP Semiconductors is an AEC-Q100 Grade 1 qualified low-ohmic SPST analog switch with active-HIGH enable (E), bidirectional Y/Z signal path, and 0.5 Ω typical ON resistance at 2.7 V and 4.3 V supply. It operates from 1.4 V to 4.3 V across −40 °C to +125 °C and supports automotive infotainment audio routing.
For engineers reviewing the NX3L1G66GW-Q100 datasheet, NX3L1G66GW-Q100 pinout, NX3L1G66GW-Q100 application, or NX3L1G66GW-Q100 equivalent, key selection criteria include its Schmitt-triggered enable input, 350 mA continuous current rating, <9 ns disable time at 2.7 V+, and −90 dB OFF-state isolation at 100 kHz - all validated for automotive-grade signal switching.
Technical Context
The NX3L1G66GW-Q100 implements a CMOS transmission-gate topology with Schmitt-trigger action on the E input, enabling robust operation with slow-rising control signals. Its bidirectional architecture allows signal passage from Y to Z or Z to Y without polarity constraints, supporting rail-to-rail analog signals up to VCC.
Static performance is defined by low ON-resistance flatness (0.13 Ω typical at 2.7 V), sub-1 nA OFF-state leakage over full temperature range, and high noise immunity via integrated ESD protection exceeding 4 kV IEC61000-4-2 on switch ports.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (typ) | 0.50 Ω at VCC = 2.7 V and 4.3 V - ensures minimal insertion loss in audio and sensor signal paths |
| 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 automotive subsystems |
| Disable Time (max) | 9 ns at VCC ≥ 2.3 V - supports high-speed multiplexing in USB 2.0 or MIPI D-PHY auxiliary channels |
| OFF-State Isolation | −90 dB at 100 kHz - prevents crosstalk between adjacent audio or CAN FD diagnostic lines |
| Continuous Switch Current | 350 mA at 3.3 V - sustains reliable operation under sustained load in power management routing |
| ESD Protection (IEC61000-4-2) | 4000 V contact discharge on Y/Z ports - meets automotive system-level EMC requirements |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine bay and ADAS module deployment |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package, 5-lead, 1.25 mm body width, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Y) | Independent analog I/O | Bidirectional signal terminal - connects to source or load without polarity restriction |
| 2 (Z) | Independent analog I/O | Complementary bidirectional terminal - forms switch path with Y when E is HIGH |
| 3 (GND) | Ground reference | 0 V return path for internal logic and switch substrate - must be low-impedance for THD < 0.02 % |
| 4 (E) | Enable input (active HIGH) | Schmitt-triggered control - tolerates slow edges; VIH = 0.7 VCC min above 2.7 V for noise margin |
| 5 (VCC) | Positive supply | Power rail for analog switch and logic - supports 1.4–4.3 V; decoupling required within 3 mm |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with lifetime reliability testing per automotive stress standards |
| Rail-to-rail analog signal handling | Supports input amplitudes from GND to VCC - eliminates level-shifting in battery-supplied sensor interfaces |
| Low ON-resistance flatness (0.13 Ω) | Minimizes harmonic distortion (<0.02 % THD at 2.3 V+) in audio and precision ADC front-end switching |
| High-speed switching (≤9 ns disable) | Enables time-critical signal gating in camera serial link (C-PHY) or LIN bus diagnostics |
| Input voltage tolerance beyond VCC | E pin accepts up to 4.6 V regardless of VCC - simplifies interfacing with higher-voltage microcontrollers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DGSR | Higher 0.9 Ω typical RON at 3.3 V; no AEC-Q100 qualification; 5-pin VSSOP package | Targeted at industrial/commercial portable electronics, not automotive environments | Select only if AEC-Q100 compliance is unnecessary and board space permits larger VSSOP footprint |
| MAX4617EUT+T | 0.8 Ω typical RON; ±15 V dual-supply capable; requires external VL for logic level translation | Designed for industrial test equipment with bipolar signal ranges, not unipolar automotive rails | Choose when switching signals beyond VCC/GND or requiring negative voltage support - not for 1.4–4.3 V automotive rails |
Compared with TS5A23157DGSR and MAX4617EUT+T, the NX3L1G66GW-Q100 uniquely delivers automotive-grade reliability, lowest RON in its voltage class, and native 1.4 V operation - making it the sole option for AEC-Q100-compliant, low-voltage, high-fidelity analog routing in modern vehicles.

FAQ
What is the maximum continuous current rating for the NX3L1G66GW-Q100?
The NX3L1G66GW-Q100 supports 350 mA continuous current at 3.3 V supply, verified across −40 °C to +125 °C. This rating applies to both Y and Z terminals under bidirectional conduction. Peak pulsed current reaches 500 mA at 1 ms/10 % duty cycle. Exceeding these values risks thermal shutdown or permanent damage per limiting values in Table 5.
Does the NX3L1G66GW-Q100 support rail-to-rail analog signal switching?
Yes, the NX3L1G66GW-Q100 allows signals with amplitude up to VCC to pass bidirectionally between Y and Z terminals. Its CMOS transmission-gate architecture supports voltages from GND to VCC without level-shifting, enabling direct connection to sensors, audio codecs, and ADCs operating at the same supply rail.
Is the enable input (E) of the NX3L1G66GW-Q100 compatible with standard TTL logic levels?
Yes - the NX3L1G66GW-Q100's E pin features Schmitt-trigger action and accepts TTL-compatible inputs at 3.0 V supply: VIH ≥ 2.0 V and VIL ≤ 0.8 V per Table 7. Input voltage tolerance extends to 4.6 V regardless of VCC, allowing direct interface with 5 V microcontrollers without external level shifters.
What is the OFF-state isolation performance of the NX3L1G66GW-Q100 at 100 kHz?
The NX3L1G66GW-Q100 delivers −90 dB OFF-state isolation at 100 kHz (Table 12), measured with 50 Ω termination. This high isolation suppresses crosstalk between adjacent switched signals - critical in multi-protocol automotive diagnostics tools where CAN FD, LIN, and UART share proximity on PCBs.
How does the NX3L1G66GW-Q100 handle ESD events on its analog switch terminals?
The NX3L1G66GW-Q100 provides 4000 V contact discharge ESD protection per IEC61000-4-2 on Y and Z switch ports (Table 2). Combined with 7500 V HBM and 1000 V CDM ratings, this ensures robustness against handling and system-level transients in automotive assembly and service environments.
