Product details
Overview
NX3L2T384GT,115 from NXP Semiconductors is a dual low-ohmic SPST analog switch with active-low enable inputs, 0.5 Ω typical ON resistance at 2.7 V and 4.3 V supply, ±350 mA continuous switch current, and operation across −40 °C to +125 °C. It enables bidirectional signal routing (nY ↔ nZ) up to VCC amplitude in portable audio and interface signal path switching.
For engineers reviewing the NX3L2T384GT,115 datasheet, NX3L2T384GT,115 pinout, NX3L2T384GT,115 application, or NX3L2T384GT,115 equivalent, key selection criteria include 1.4–4.3 V wide supply range, Schmitt-triggered enable for slow-edge tolerance, 1.8 V logic compatibility at 3.6 V VCC, sub-50 ns enable/disable timing, and ESD robustness exceeding 4 kV IEC61000-4-2 on switch ports.
Technical Context
The NX3L2T384GT,115 integrates two independent CMOS transmission gates, each with separate enable (nE) and bidirectional I/O (nY/nZ). Its Schmitt-trigger input on nE ensures reliable switching with slow-rising/falling control signals, while its low-threshold VIH/VIL allows direct interfacing with 1.8 V logic even at VCC = 3.6 V without level shifters.
Each channel delivers flat ON resistance (0.13 Ω typical flatness at 2.7 V), minimal charge injection (3 pC at ≤3.3 V), and high OFF isolation (−90 dB at 100 kHz), supporting high-fidelity analog signal routing in battery-powered systems where power efficiency and signal integrity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 4.3 V - supports single-supply operation from Li-ion battery (3.0–4.2 V) or dual-supply rail (1.8 V logic + 3.3 V analog) |
| ON Resistance (typ) | 0.50 Ω at VCC = 2.7 V and 4.3 V - ensures <0.1% signal attenuation for 100 mV–3 V audio/USB signals |
| Switch Current (cont.) | ±350 mA - handles headphone driver output or USB data line surge currents without thermal derating |
| Enable Timing (ten/tdis) | 22 ns / 11 ns at VCC ≥2.7 V - enables fast multiplexing in real-time audio routing or sensor channel selection |
| ESD Robustness | IEC61000-4-2 contact discharge ≥4000 V on switch ports - eliminates need for external TVS diodes in handheld ESD-prone interfaces |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood or industrial ambient environments without derating |
| OFF Isolation | −90 dB at 100 kHz - prevents crosstalk between adjacent audio channels or RF-sensitive analog paths |
Pinout & Package
XSON8 package (SOT833-1): plastic extremely thin small outline, no leads, 8-terminal, body size 1.0 × 1.95 × 0.5 mm, pin 1 indicator in lower-left corner below marking code M84.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1Y, 5Y | Channel 1 bidirectional I/O | Connects to source or load; supports signal flow in either direction up to VCC amplitude |
| 2Y, 6Y | Channel 2 bidirectional I/O | Independent of Channel 1; enables dual-path routing without interaction |
| 1E, 7E | Channel 1 enable (active LOW) | Drives LOW to turn ON switch; Schmitt trigger accepts slow edges and 1.8 V logic at 3.6 V VCC |
| 2E, 3E | Channel 2 enable (active LOW) | Independent control; allows asynchronous switching of two signal paths |
| GND (Pin 4) | Ground reference | Common return for all internal circuitry; must be low-impedance for noise immunity |
| VCC (Pin 8) | Supply voltage | Powers analog switch core and enable logic; also defines maximum signal swing (0 to VCC) |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.4–4.3 V) | Enables direct integration into mixed-voltage systems (e.g., 1.8 V controller + 3.3 V sensor bus) without external regulators |
| 0.13 Ω ON resistance flatness | Maintains consistent gain and phase response across full signal swing, critical for audio fidelity and precision ADC/DAC interfaces |
| 1.8 V logic-compatible enable | Eliminates level translators when controlled by low-power microcontrollers or baseband processors operating at 1.8 V |
| −90 dB OFF-state isolation | Prevents audible crosstalk in stereo headphone outputs or leakage between isolated sensor channels |
| 3 pC typical charge injection | Minimizes voltage glitch on high-impedance nodes (e.g., SAR ADC sample capacitors), reducing settling time and error |

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 bidirectional level translator with auto-direction sensing; no analog switch function; higher ICC (10 µA vs. 100 nA) | Requires external analog switches for signal routing; suited only when level translation is primary need | Select only if bidirectional voltage-level shifting (not analog signal switching) is required |
| MAX4617EUA+ | Single SPST switch, 5-pin µMAX; 3.5 Ω ON resistance at 3 V; −40 °C to +85 °C only; no Schmitt trigger on enable | Limited to single-channel use; insufficient temperature range for automotive or industrial deployment | Choose only for cost-sensitive, single-channel, commercial-temp designs where 0.5 Ω performance is not critical |
Compared with TXS0102DCUR and MAX4617EUA+, the NX3L2T384GT,115 uniquely combines dual-channel analog switching, sub-0.5 Ω ON resistance, 125 °C operation, and Schmitt-triggered enables-enabling compact, robust, and high-fidelity signal routing without auxiliary components.

FAQ
What is the maximum signal voltage the NX3L2T384GT,115 can pass?
The NX3L2T384GT,115 supports bidirectional analog signal transmission with amplitude up to VCC. When supplied at 4.3 V, it passes signals from 0 V to 4.3 V without distortion or clipping. This capability is explicitly specified in the functional description and recommended operating conditions (VSW = 0 to VCC), and confirmed by the 4.3 V maximum supply rating in Table 5.
Does the NX3L2T384GT,115 require external level-shifting when driven by a 1.8 V microcontroller?
No, the NX3L2T384GT,115 does not require external level-shifting. Its enable inputs feature Schmitt-trigger action and low VIH thresholds (e.g., 1.3 V max at VCC = 2.7–3.6 V), allowing direct 1.8 V logic control even at VCC = 3.6 V. This is documented in Table 7 (VIH/VIL specs) and the General Description section.
What is the thermal performance of the NX3L2T384GT,115 in the XSON8 package?
The NX3L2T384GT,115 in SOT833-1 (XSON8) has a total power dissipation limit of 250 mW at Tamb = −40 °C to +125 °C. Above 118 °C, Ptot derates linearly at 7.8 mW/K. This thermal behavior is defined in Table 5 (Limiting Values) and applies specifically to the SOT833-1 variant per ordering information Table 1.
How does the NX3L2T384GT,115 handle ESD events on its switch terminals?
The NX3L2T384GT,115 provides IEC61000-4-2 contact discharge ESD protection exceeding 4000 V on its switch ports (nY/nZ), as stated in the Features and Benefits section and Table 5. This eliminates the need for discrete TVS diodes in handheld device interfaces subject to user-handling ESD.
Is the NX3L2T384GT,115 pin-compatible with other variants in the NX3L2T384 family?
No, the NX3L2T384GT,115 (SOT833-1, XSON8, 1.0 × 1.95 mm) is not pin-compatible with NX3L2T384GD (SOT996-2, XSON8, 3.0 × 2.0 mm) or NX3L2T384GM (SOT902-2, XQFN8, 1.6 × 1.6 mm), as confirmed by distinct pin configurations in Figures 3–5 and differing mechanical dimensions in Table 1. PCB layout must match the specific package variant ordered.
