Product details
Overview
NX3L1T53GT,115 from NXP Semiconductors is a low-ohmic SPDT analog switch configured as a 2:1 multiplexer/demultiplexer with active-low enable (E), digital select (S), common port (Z), and dual I/O ports (Y0/Y1). It delivers 0.5 Ω typical ON resistance at 4.3 V supply, supports 1.4–4.3 V operation, and handles ±350 mA continuous current - enabling high-fidelity audio routing in portable media players.
For engineers reviewing the NX3L1T53GT,115 datasheet, NX3L1T53GT,115 pinout, NX3L1T53GT,115 application, or NX3L1T53GT,115 equivalent, key selection criteria include its break-before-make switching, 1.8 V logic compatibility at 3.6 V supply, −40 °C to +125 °C temperature range, and ESD robustness exceeding 8 kV (IEC61000-4-2 contact).
Technical Context
The NX3L1T53GT,115 implements CMOS transmission-gate architecture with Schmitt-trigger inputs for noise immunity and voltage-tolerant control logic that accepts inputs up to VCC + 0.5 V. Its bidirectional signal path supports rail-to-rail analog transmission (0 V to VCC) with minimal distortion.
Break-before-make timing is guaranteed by design (as low as 2 ns at 4.3 V), and dynamic performance includes 60 MHz −3 dB bandwidth, −90 dB OFF-state isolation, and <15 pC charge injection - making it suitable for precision audio and high-speed data switching where signal integrity is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 4.3 V - enables single-supply operation across battery-powered and mixed-voltage systems. |
| ON Resistance (Typ) | 0.50 Ω at VCC = 4.3 V - ensures minimal insertion loss and thermal drift in audio and sensor signal paths. |
| Switch Current | ±350 mA continuous - supports driving headphones, sensors, or ADC/DAC interfaces without external buffering. |
| Operating Temperature | −40 °C to +125 °C - qualified for automotive infotainment and industrial portable equipment. |
| ESD Robustness | 8 kV IEC61000-4-2 contact discharge on switch ports - reduces need for external protection in handheld designs. |
| Enable Propagation Delay | 22 ns typical at 3.6–4.3 V - enables fast channel reconfiguration in real-time audio mixing or sensor multiplexing. |
| Charge Injection | 15 pC at VCC = 4.3 V - limits DC offset shift in precision sampling circuits and audio DAC outputs. |
Pinout & Package
Package: XSON8 (SOT833-1), plastic extremely thin small outline package, no leads; 8 terminals; body dimensions 1.0 × 1.95 × 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Z | Common I/O port | Bidirectional signal path shared between Y0 and Y1; supports rail-to-rail analog signals up to VCC. |
| E | Active-low enable input | Drives entire switch OFF when HIGH; allows system-level power gating of signal routing. |
| GND (pins 3 & 4) | Ground reference | Dual ground pins reduce ground bounce and improve PSRR in high-speed switching. |
| S | Digital select input | Chooses Y0→Z or Y1→Z path; Schmitt-trigger input tolerates slow rise/fall times and 1.8 V logic levels. |
| Y1 | Independent I/O port | Connects to Z when S = HIGH and E = LOW; supports bidirectional signal flow. |
| Y0 | Independent I/O port | Connects to Z when S = LOW and E = LOW; identical electrical characteristics to Y1. |
| VCC | Supply voltage | Power rail for analog and digital sections; also defines maximum signal swing (0 V to VCC). |
Key Features
| Feature | Design Value |
|---|---|
| 1.8 V logic compatibility at 3.6 V supply | Eliminates level shifters when interfacing with ultra-low-power microcontrollers in battery-constrained devices. |
| Break-before-make switching | Prevents momentary short-circuit between Y0 and Y1 during channel transitions - critical for avoiding audio pops or sensor crosstalk. |
| Low ON-resistance flatness (0.13 Ω) | Ensures consistent gain and phase response across input voltage range - essential for high-fidelity audio routing. |
| High OFF-state isolation (−90 dB) | Minimizes signal leakage between inactive channels - preserves SNR in multi-source audio or sensor multiplexing. |
| Control input voltage tolerance (> VCC) | Accepts digital inputs up to VCC + 0.5 V, simplifying interface with higher-voltage controllers without clamping diodes. |

The NX3L1T53GT,115 supports bidirectional analog signal transmission from 0 V to VCC. At its maximum rated supply voltage of 4.3 V, it can reliably switch signals up to 4.3 V peak-to-peak without distortion or damage. This rail-to-rail capability is confirmed in the functional description and recommended operating conditions table of the official NXP datasheet Rev. 8.
Does the NX3L1T53GT,115 support 1.8 V logic control when powered at 3.6 V?
Yes, the NX3L1T53GT,115 explicitly supports 1.8 V logic-level control inputs (S and E) while operating at VCC = 3.6 V, as stated in the "Features and benefits" section and verified in Table 7 (VIH/VIL thresholds). This eliminates the need for external level translators in mixed-voltage portable designs.
What is the guaranteed break-before-make time for the NX3L1T53GT,115?
The NX3L1T53GT,115 guarantees break-before-make timing by design, with measured values as low as 2 ns at VCC = 3.6–4.3 V (Table 9). This parameter is specified across the full −40 °C to +125 °C temperature range and ensures no overlap between Y0 and Y1 conduction paths during switching.
Can the NX3L1T53GT,115 be used in automotive applications?
Yes - the NX3L1T53GT,115 is qualified for operation from −40 °C to +125 °C and features ESD robustness exceeding 8 kV (IEC61000-4-2 contact), meeting key requirements for automotive infotainment and body electronics. While not AEC-Q100 certified *by part number*, its temperature grade and stress ratings align with automotive subsystem use cases.
