Product details
Overview
NX3L4051PW,118 from NXP Semiconductors is a single low-ohmic 8-channel analog switch configured as a bidirectional 1-of-8 multiplexer/demultiplexer with common terminal Z, three digital select inputs (S1–S3), enable input E, and operating supply range 1.4 V to 4.3 V. It delivers 0.5 Ω typical ON resistance at 4.3 V, supports 1.8 V logic control in 3.3 V systems, and enables signal routing up to VCC amplitude - used in portable audio signal path selection.
For engineers reviewing the NX3L4051PW,118 datasheet, NX3L4051PW,118 pinout, NX3L4051PW,118 application, or NX3L4051PW,118 equivalent, key selection criteria include guaranteed break-before-make timing (≤9 ns), ultra-low charge injection (≤15 pC), high OFF-state isolation (−90 dB), and compatibility with −40 °C to +125 °C industrial temperature operation.
Technical Context
The NX3L4051PW,118 implements a CMOS-based 1-of-8 decoder architecture with active-low enable (E) controlling all eight Yn–Z switches simultaneously. Schmitt-trigger inputs on S1/S2/S3/E provide noise immunity against slow-rising signals, while level-tolerant digital inputs accept voltages up to VCC regardless of supply voltage.
Its bidirectional analog switching path supports transmission of signals from Z to any Yn or vice versa, with flat ON resistance (0.13 Ω max mismatch) ensuring minimal harmonic distortion (<0.02 % THD at 2.7 V–4.3 V) and wideband frequency response (15 MHz −3 dB bandwidth).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 4.3 V - supports direct integration into 1.8 V, 2.5 V, 3.3 V, and 4.3 V systems without level shifters |
| ON Resistance (Typ) | 0.5 Ω at VCC = 4.3 V - enables low-loss analog signal routing for precision sensor or audio paths |
| ON Resistance Flatness | 0.13 Ω max - ensures consistent channel-to-channel gain matching in multiplexed measurement systems |
| Break-Before-Make Time | ≤9 ns - prevents momentary shorting between channels during switching, critical for glitch-free signal routing |
| Charge Injection | 15 pC max - minimizes voltage transients at switched nodes, preserving DC accuracy in data acquisition front-ends |
| OFF-State Isolation | −90 dB - suppresses crosstalk between inactive channels in multi-signal routing applications |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial control, and extended-life portable equipment |
Pinout & Package
TSSOP16 package (SOT403-1): plastic thin shrink small outline, 16-lead, body width 4.4 mm, 1.1 mm max height, lead pitch 0.65 mm.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Z | Common bidirectional analog terminal - connects to shared signal path (e.g., ADC input or codec line) |
| 2–4, 5, 12–16 | Y0–Y7 | Eight independent analog I/O terminals - each routes to Z when selected; no internal connection between Yn pins |
| 6 | E | Active-low enable - HIGH disables all switches into high-impedance OFF state, independent of S1–S3 |
| 7–9 | S1, S2, S3 | Binary address inputs - decode one of eight Yn channels to connect to Z (L/L/L → Y0, H/H/H → Y7) |
| 8 | GND | Ground reference - must be low-impedance return for analog and digital domains to minimize noise coupling |
| 16 | VCC | Positive supply - powers analog switch core and input buffers; also defines maximum signal swing (0 to VCC) |
Key Features
| Feature | Design Value |
|---|---|
| 1.8 V logic-compatible control | Accepts 1.8 V inputs at VCC = 3.6 V with no increase in ICC - eliminates level translators in mixed-voltage SoC interfaces |
| Input voltage tolerance | Digital inputs tolerate VI up to VCC + 0.5 V - allows safe interfacing with overvoltage-tolerant microcontrollers |
| ESD robustness | 8 kV IEC61000-4-2 contact discharge on switch ports - sustains handling and board-level ESD events without latch-up |
| Low quiescent current | 100 nA max ICC at VCC = 3.6 V - enables always-on signal routing in battery-powered devices |
| High current capability | 350 mA continuous per channel - supports driving low-impedance loads like piezo buzzers or LED drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3A4751PWR | Higher ON resistance (0.9 Ω typ at 3.3 V); no Schmitt-trigger inputs; 1.65 V–3.6 V supply only | Limited to commercial temp (−40 °C to +85 °C); lower ESD rating (2 kV HBM) | Choose for cost-sensitive consumer designs where 125 °C operation and robust ESD are not required. |
| ADG1408BRUZ | Higher supply range (±5 V dual or 5 V single); 0.6 Ω ON resistance; requires external VLOGIC pin for 1.8 V control | Designed for precision instrumentation; larger TSSOP-16 footprint (5.1 mm width vs. 4.4 mm) | Choose when bipolar signal handling or sub-0.1 % RON flatness is mandatory, accepting higher cost and layout area. |

FAQ
What is the maximum signal voltage the NX3L4051PW,118 can switch?
The NX3L4051PW,118 supports bidirectional analog signal transmission with amplitude up to VCC - meaning at VCC = 4.3 V, it safely switches signals from 0 V to 4.3 V peak-to-peak. Exceeding VCC risks violating the absolute maximum switch voltage rating of VCC + 0.5 V, potentially causing latch-up or permanent damage. Always maintain VSW ≤ VCC in normal operation.
Does the NX3L4051PW,118 require external pull-up or pull-down resistors on its S1–S3 or E pins?
No, the NX3L4051PW,118 integrates Schmitt-trigger inputs on S1, S2, S3, and E, eliminating the need for external biasing resistors. These inputs accept clean TTL- or CMOS-level logic directly and tolerate slow edge rates - simplifying PCB layout and reducing component count compared to non-Schmitt alternatives.
Can the NX3L4051PW,118 be used in a 1.4 V system with full functionality?
Yes - the NX3L4051PW,118 is fully specified down to 1.4 V supply, delivering 1.7 Ω typical ON resistance and maintaining break-before-make timing (≤100 ns), THD (<0.15 %), and −90 dB isolation. Its 1.4 V minimum rating enables use in ultra-low-power wearable sensors and energy-harvesting subsystems without performance compromise.
How does the NX3L4051PW,118 handle signals exceeding the supply rail?
The NX3L4051PW,118 does not support rail-to-rail or beyond-rail signal switching. Its absolute maximum switch voltage is VCC + 0.5 V (per Table 5). Applying signals > VCC risks forward-biasing internal ESD diodes, causing excessive current flow, thermal stress, or irreversible damage. Signal amplitude must remain within 0 V to VCC for reliable operation.
Is the NX3L4051PW,118 pin-compatible with other members of the NX3L4051 family?
Yes - the NX3L4051PW,118 shares identical pinout and function with NX3L4051HR (HXQFN16) per Figures 3 and 4 of the datasheet. Both variants use the same SOT403-1 (TSSOP16) pin numbering for the 16-pin configuration, enabling drop-in replacement where thermal or board-space constraints permit the package swap.
