Product details
Overview
NX3L1G53GT,115 from NXP Semiconductors is a low-ohmic SPDT analog switch configured as a 2:1 multiplexer/demultiplexer, featuring active-low enable (E), digital select (S), common port (Z), and dual I/O ports (Y0/Y1). It operates from 1.4 V to 4.3 V, delivers 0.50 Ω typical ON resistance at 2.7 V/4.3 V, supports ±350 mA continuous current, and functions across −40 °C to +125 °C - ideal for audio routing in portable media players.
For engineers reviewing the NX3L1G53GT,115 datasheet, NX3L1G53GT,115 pinout, NX3L1G53GT,115 application, or NX3L1G53GT,115 equivalent, key selection criteria include guaranteed break-before-make switching, sub-1 Ω ON resistance flatness (0.13 Ω), −90 dB OFF-state isolation, <10 pC charge injection at 3.3 V, and compatibility with TTL logic at 3.0 V supply.
Technical Context
The NX3L1G53GT,115 implements CMOS-based transmission gate architecture with Schmitt-trigger inputs on S and E pins, enabling robust operation with slow-rising/falling control signals. Its bidirectional signal path supports voltage swings up to VCC on all ports (Z, Y0, Y1) without level-shifting.
Break-before-make timing is guaranteed by design (tb-m ≤ 10 ns at VCC ≥ 2.7 V), eliminating signal shorting during channel switching. The device maintains low THD (≤0.02% at VCC ≥ 2.3 V) and wide −3 dB bandwidth (60 MHz), making it suitable for high-fidelity analog signal routing in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 4.3 V - enables direct integration with 1.8 V, 2.5 V, 3.3 V, and 4.2 V Li-ion battery rails without regulators. |
| ON Resistance (Typ) | 0.50 Ω at VCC = 2.7 V and 4.3 V - minimizes insertion loss and thermal drift in precision analog paths. |
| ON Resistance Flatness | 0.13 Ω at VCC = 2.7 V - ensures consistent signal amplitude across full input voltage range (0–VCC). |
| Switch Current Rating | ±350 mA continuous - supports high-drive audio codecs and sensor interface loads. |
| OFF-State Isolation | −90 dB at 100 kHz - prevents crosstalk between inactive channels in multi-source systems. |
| Charge Injection | 9 pC at VCC = 3.3 V - reduces glitch-induced errors in sampled-data circuits like ADC front-ends. |
| Enable Time (ten) | 15 ns typical at VCC = 3.6 V - enables fast channel reconfiguration in real-time audio mixing. |
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 |
|---|---|---|
| 1 - Z | Common I/O terminal | Bidirectional signal path shared between Y0 and Y1; accepts/receives analog or digital signals up to VCC. |
| 2 - E | Active-low enable input | Drives entire switch OFF when HIGH; enables channel selection only when LOW (logic 0). |
| 3 - GND | Ground reference | Primary return path for supply and signal currents; two GND pins (3 & 4) reduce ground impedance. |
| 4 - GND | Ground reference | Second ground terminal for improved thermal dissipation and noise rejection in high-frequency operation. |
| 5 - S | Digital select input | Chooses Y0→Z (S = LOW) or Y1→Z (S = HIGH); Schmitt-trigger input tolerates slow edges. |
| 6 - Y1 | Independent I/O terminal | Second selectable path; bidirectional, supports same voltage range and current as Y0 and Z. |
| 7 - Y0 | Independent I/O terminal | First selectable path; electrically matched to Y1 for channel-to-channel consistency. |
| 8 - VCC | Positive supply rail | Power source for internal logic and switch transistors; also defines maximum analog signal swing. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed by design (tb-m ≤ 10 ns), preventing momentary short-circuit between Y0 and Y1 during transition. |
| ESD protection | 8 kV IEC61000-4-2 contact discharge on switch ports - eliminates need for external TVS in handheld interfaces. |
| Wide supply range | 1.4 V to 4.3 V operation - supports single-cell Li-ion (3.0–4.2 V), NiMH (1.2 V × 2), and low-power MCU I/O domains. |
| Low THD | 0.02% at 20 Hz–20 kHz (VCC ≥ 2.3 V) - preserves audio fidelity in headphone and speaker driver paths. |
| High noise immunity | Schmitt-trigger inputs on S/E pins - reject >200 ns/V input noise without external filtering or debouncing. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - ensures robustness against transient overvoltage events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TS5A23157DCUR | Higher ON resistance (0.9 Ω typ @ 3.3 V), smaller X2QFN8 (1.4 × 1.8 mm), no specified 125 °C operation. | Targeted at consumer-grade 3.3 V systems only; lacks extended temperature qualification and ESD robustness (IEC61000-4-2 not rated). | Select TS5A23157DCUR only for cost-sensitive, non-automotive designs where 125 °C operation and 8 kV ESD are not required. |
| Analog Devices ADG858BRMZ-REEL7 | Wider supply (1.8–5.5 V), higher ON resistance (0.55 Ω min @ 3 V), larger MSOP-8 package (3 × 3 mm), no break-before-make guarantee. | Optimized for general-purpose instrumentation; lacks guaranteed break-before-make and fails to meet 125 °C ambient spec. | Choose ADG858BRMZ-REEL7 for legacy PCBs requiring MSOP-8 footprint or when 5.5 V operation is mandatory. |
Compared with TS5A23157DCUR and ADG858BRMZ-REEL7, the NX3L1G53GT,115 uniquely combines 125 °C operation, 8 kV IEC61000-4-2 ESD on switch ports, guaranteed break-before-make, and 1.0 × 1.95 mm XSON8 footprint - making it the only option qualified for space-constrained, high-reliability portable audio and industrial sensing.

FAQ
What is the maximum continuous current rating for the NX3L1G53GT,115?
The NX3L1G53GT,115 supports ±350 mA continuous current per channel under 3.3 V supply conditions, as specified in Table 5 of the official NXP datasheet Rev. 7.1. This rating applies to bidirectional conduction through any active path (Z↔Y0 or Z↔Y1) and is validated across the full −40 °C to +125 °C operating range. Peak pulsed current reaches ±500 mA at 1 ms duration and <10% duty cycle.
Does the NX3L1G53GT,115 support true break-before-make switching?
Yes, the NX3L1G53GT,115 guarantees break-before-make timing by design, with measured tb-m ≤ 10 ns at VCC ≥ 2.7 V (Table 9, Rev. 7.1). This eliminates risk of momentary short-circuit between Y0 and Y1 during channel transitions, a critical requirement for protecting sensitive audio codecs and sensor front-ends.
What is the ON resistance flatness specification for the NX3L1G53GT,115 at 2.7 V supply?
At VCC = 2.7 V, the NX3L1G53GT,115 exhibits 0.13 Ω typical ON resistance flatness (ΔRON), defined as the difference between max and min RON across the full 0–VCC input voltage range. This value is confirmed in Table 8 of the NXP datasheet Rev. 7.1 and ensures minimal signal distortion in high-fidelity analog paths.
Can the NX3L1G53GT,115 operate with a 1.4 V supply voltage?
Yes, the NX3L1G53GT,115 is fully specified down to 1.4 V supply voltage, with 1.6 Ω typical ON resistance and 1.0 Ω flatness at that rail (Table 8, Rev. 7.1). It maintains functional logic thresholds, Schmitt-trigger input hysteresis, and −40 °C to +125 °C operation across the entire 1.4–4.3 V range.
Is the NX3L1G53GT,115 pin-compatible with other variants in the NX3L1G53 family?
No - the NX3L1G53GT,115 uses SOT833-1 (XSON8, 1.0 × 1.95 mm), while NX3L1G53GD uses SOT996-2 (XSON8, 3.0 × 2.0 mm) and NX3L1G53GM uses SOT902-2 (XQFN8, 1.6 × 1.6 mm). Although all share identical pin functions and logic behavior, their physical footprints differ significantly; PCB layout must be tailored to SOT833-1 for NX3L1G53GT,115.
