Product details

Overview

NX3V1T66GM,115 from NXP Semiconductors is a low-ohmic SPST analog switch in XSON6 package, operating from 1.4 V to 4.3 V supply, featuring 0.25 Ω typical ON resistance at 4.3 V, Schmitt-trigger enable input (E), and bidirectional signal routing between Y and Z terminals. It enables 4.3 V analog signal switching under 1.8 V digital control in portable audio paths.

For engineers reviewing the NX3V1T66GM,115 datasheet, NX3V1T66GM,115 pinout, NX3V1T66GM,115 application, or NX3V1T66GM,115 equivalent, key selection criteria include ultra-low R_ON flatness (0.1 Ω), −40 °C to +125 °C operation, 6000 V IEC61000-4-2 ESD rating on switch ports, and 1.8 V logic compatibility at 3.6 V V_CC.

Technical Context

The NX3V1T66GM,115 implements a CMOS transmission gate architecture with Schmitt-trigger action on the active-HIGH enable (E) pin, enabling robust noise immunity against slow-rising control signals. Its rail-to-rail analog signal handling (up to V_CC) and bidirectional conduction support both Y→Z and Z→Y paths without polarity constraints.

Dynamic performance includes 11 ns disable time (t_dis) and 18 ns enable time (t_en) at V_CC = 3.6–4.3 V, −90 dB OFF-state isolation at 100 kHz, and <0.01% THD at 20 kHz with 2 V_p-p input-critical for high-fidelity audio routing in space-constrained devices.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.4 V to 4.3 V - supports single-supply operation across Li-ion battery discharge curve and 1.8/2.5/3.3/4.3 V system rails.
Typical ON Resistance	0.25 Ω at V_CC = 4.3 V - minimizes insertion loss and voltage drop in high-current analog paths (e.g., headphone drivers).
ON Resistance Flatness	0.1 Ω max - ensures consistent signal amplitude across full input voltage range (0 to V_CC), critical for precision audio and sensor interfaces.
Enable Input Threshold	V_IH = 1.4 V (min) at V_CC = 4.3 V - allows direct interfacing with 1.8 V GPIO without level shifters.
ESD Rating (Switch Ports)	±6000 V IEC61000-4-2 contact discharge - protects sensitive analog inputs/outputs in handheld consumer devices.
Operating Temperature	−40 °C to +125 °C - qualified for extended industrial and automotive cabin-adjacent applications.
Continuous Switch Current	±500 mA - supports high-drive audio outputs and power path switching in portable media players.

Pinout & Package

XSON6 (SOT886) package: plastic extremely thin small outline, no leads, 6-terminal surface-mount device with 1.0 × 1.45 × 0.5 mm body height. Pin 1 indicator located at lower-left corner below marking code "dO".

Pin/Terminal	Circuit Role	Design Meaning
1 (Y)	Independent analog I/O terminal	Bidirectional signal path; connects to source or load depending on system topology (e.g., codec output or speaker input).
2 (Z)	Independent analog I/O terminal	Complementary bidirectional port; forms SPST switch path with Y when E = HIGH.
3 (GND)	Ground reference	0 V return for analog and digital domains; must be low-impedance to minimize crosstalk and THD.
4 (E)	Active-HIGH enable input	Schmitt-triggered control pin; accepts 1.8 V logic at V_CC = 3.6 V; tolerant of slow edges up to 200 ns/V transition rate.
5 (n.c.)	No-connect terminal	Internally unconnected; must remain floating-no external bias or tie-down required.
6 (V_CC)	Positive supply rail	Power input for analog switch core and enable logic; decoupling capacitor (100 nF) recommended within 2 mm.

Key Features

Feature	Design Value
Rail-to-rail analog switching	Signals from 0 V to V_CC pass bidirectionally with <0.4 V voltage drop at ±500 mA - eliminates clipping in audio line-level routing.
Ultra-low charge injection	6.5 pC typical (V_CC ≤ 3.3 V) - prevents audible pop/click during switching in headphone amplifiers and DAC outputs.
High OFF-state isolation	−90 dB at 100 kHz - suppresses crosstalk between adjacent audio channels or RF/analog sections in compact PCB layouts.
Low dynamic power consumption	150 nA max ICC at V_CC = 4.3 V - enables always-on signal routing in battery-powered sleep modes.
Wide temperature specification	Guaranteed R_ON, t_en, and leakage performance from −40 °C to +125 °C - supports deployment in automotive infotainment and industrial HMI displays.

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TXS0102DCUR	2-channel level translator with integrated switch; higher R_ON (6 Ω typical); requires dual supply (1.2–3.6 V & 1.65–5.5 V).	Designed for bidirectional data bus translation (I²C, UART), not optimized for analog signal fidelity or high-current switching.	Select TXS0102DCUR only when level translation and switching are co-required; avoid for audio or precision analog due to R_ON and THD limitations.
TMUX1574RSVR	4-channel SPDT; 0.5 Ω R_ON at 3.3 V; no Schmitt trigger; −40 °C to +125 °C; 2 kV HBM ESD.	Higher channel count and smaller 1.6 × 1.6 mm QFN package; lacks IEC61000-4-2 ESD rating and 1.8 V logic compatibility at 3.6 V V_CC.	Choose TMUX1574RSVR for multi-channel routing where board space permits larger footprint and ESD requirements are less stringent.

Compared with TXS0102DCUR and TMUX1574RSVR, NX3V1T66GM,115 delivers superior analog performance (0.25 Ω R_ON, −90 dB isolation, 6.5 pC charge injection) and robust ESD protection (6000 V IEC61000-4-2) in the smallest 1.0 × 1.45 mm XSON6 footprint-making it optimal for space- and fidelity-critical portable audio and sensor interfaces.

FAQ

What is the maximum continuous current rating for NX3V1T66GM,115?

The NX3V1T66GM,115 supports ±500 mA continuous switch current at V_CC = 3.3 V, verified per Table 5 in the datasheet. This rating applies under recommended operating conditions (−40 °C to +125 °C ambient) with proper PCB thermal relief. Exceeding this current may cause thermal shutdown or permanent damage due to power dissipation limits (250 mW total).

Does NX3V1T66GM,115 support 1.8 V logic control when powered at 4.3 V?

Yes, NX3V1T66GM,115 accepts 1.8 V logic levels on its enable (E) pin even when V_CC = 4.3 V. The VIH threshold is specified at 1.4 V minimum (Table 7), and the enable input tolerates voltages above V_CC. This eliminates level translation in mixed-voltage systems, as confirmed in Section 1 of the datasheet.

What is the OFF-state leakage current specification for NX3V1T66GM,115 at 125 °C?

At Tamb = +125 °C and V_CC = 3.6 V to 4.3 V, the OFF-state leakage current (IS(OFF)) for NX3V1T66GM,115 is ±500 nA maximum, as stated in Table 7. This value ensures minimal signal bleed in high-impedance audio or sensor paths under worst-case thermal conditions.

Is NX3V1T66GM,115 pin-compatible with other variants in the NX3V1T66 family?

No-NX3V1T66GM,115 uses the 6-pin XSON6 (SOT886) package, while NX3V1T66GW uses 5-pin TSSOP5 (SOT353-1). Pin counts, layouts, and terminal assignments differ: XSON6 includes a dedicated n.c. pin (pin 5) and V_CC on pin 6, whereas TSSOP5 places V_CC on pin 5 with no n.c. terminal. PCB redesign is required for substitution.

What ESD protection standards does NX3V1T66GM,115 meet on its analog switch ports?

NX3V1T66GM,115 meets IEC61000-4-2 contact discharge at ±6000 V on its Y and Z switch terminals, as documented in Section 2 (Features and benefits). This exceeds standard IEC Level 4 requirements and is validated per test circuit Figure 19, making it suitable for direct connection to exposed audio jacks and touch interfaces.
