Product details
Overview
NX3L4051HR,115 from NXP Semiconductors is a single low-ohmic 8-channel analog switch configured as a 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 bidirectional signal routing up to VCC in portable audio and sensor interface applications.
For engineers reviewing the NX3L4051HR,115 datasheet, NX3L4051HR,115 pinout, NX3L4051HR,115 application, or NX3L4051HR,115 equivalent, key selection criteria include its HXQFN16 thermal-enhanced package, break-before-make switching, ±350 mA continuous switch current, -40 °C to +125 °C temperature rating, and IEC61000-4-2 contact ESD immunity exceeding 8 kV on switch ports.
Technical Context
The NX3L4051HR,115 implements a CMOS-based 1-of-8 decoder architecture with Schmitt-trigger digital inputs for noise immunity and wide voltage tolerance. Its enable input (E) forces all eight channels into high-impedance OFF-state independently of select lines, supporting system-level power gating.
It operates bidirectionally between Z and any Yn channel, with ON-resistance flatness of 0.13 Ω (max) ensuring minimal signal distortion across the full 0–VCC analog swing. Switching is break-before-make guaranteed by design, eliminating transient short-circuits during channel transitions.

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 0.8 Ω typical ON resistance at 3.3 V; 0.35 Ω flatness; rated only to +85 °C. | Limited to consumer-grade portable devices; lacks 125 °C qualification and 8 kV ESD rating. | Select when cost sensitivity outweighs thermal/ESD requirements and 125 °C operation is unnecessary. |
| ADG1408YRUZ | Higher 4.7 Ω ON resistance; ±15 V dual-supply capable; SPI-controlled; 16-lead TSSOP only. | Targeted at precision instrumentation with bipolar signal ranges; not optimized for low-voltage portable battery operation. | Select for ±15 V analog systems requiring higher voltage headroom and digital addressability over SPI. |

FAQ
What is the maximum analog signal voltage the NX3L4051HR,115 can switch?
The NX3L4051HR,115 supports analog signal voltages from 0 V to VCC across all channels. With a maximum supply voltage of 4.3 V, it can reliably switch signals up to 4.3 V peak-to-peak in either direction (Z ↔ Yn). This bidirectional capability eliminates polarity constraints in sensor and audio signal routing applications. The NX3L4051HR,115 maintains specified ON resistance and leakage performance across this full range when operated within recommended conditions.
Does the NX3L4051HR,115 require external pull-up or pull-down resistors on its select inputs?
No, the NX3L4051HR,115 incorporates Schmitt-trigger action on all digital inputs (S1, S2, S3, and E), providing inherent hysteresis and noise immunity. This eliminates the need for external pull-up or pull-down resistors in most applications. Input thresholds are defined relative to VCC, with VIH = 1.4 V (min) and VIL = 0.6 V (max) at VCC = 4.3 V, allowing reliable operation with 1.8 V logic drivers even at higher supply rails. The NX3L4051HR,115 remains stable without external biasing under typical PCB trace capacitance and noise conditions.
Can the NX3L4051HR,115 be used in a 5 V system?
No-the absolute maximum supply voltage for the NX3L4051HR,115 is +4.6 V, and the recommended operating range is strictly 1.4 V to 4.3 V. Applying 5 V to VCC exceeds the limiting value and risks permanent damage. For 5 V systems, alternative analog switches such as the NX3L4053 (5 V tolerant) or TI's TMUX6208 should be evaluated. The NX3L4051HR,115 must be powered from a regulated ≤4.3 V rail, even if downstream circuitry operates at 5 V.
What is the thermal performance difference between the HXQFN16 and TSSOP16 packages for the NX3L4051HR,115?
The NX3L4051HR,115 is only offered in the HXQFN16 (SOT1039-2) package-not TSSOP16. The HXQFN16 provides superior thermal performance: 250 mW total power dissipation (vs. 500 mW for TSSOP16), but with significantly lower thermal resistance due to its exposed thermal pad and thinner profile (0.5 mm height). Its Ptot derates linearly at 16.9 mW/K above 135 °C. The NX3L4051HR,115 leverages this for compact, high-power-density layouts where board space and heat dissipation are constrained.
How does the break-before-make timing of the NX3L4051HR,115 prevent signal corruption during channel switching?
The NX3L4051HR,115 guarantees break-before-make operation by design, with a minimum tb-m of 2 ns (typical 9 ns) at VCC = 4.3 V. This ensures that the previously selected channel fully disconnects before the newly selected channel closes, eliminating momentary shorts between Yn paths. In applications like sensor multiplexing or audio routing, this prevents DC coupling transients, ground loops, or signal contention that could corrupt measurements or cause audible pops. The NX3L4051HR,115 achieves this without external timing control or sequencing logic.
