Product details
Overview
NX3L4051HR-Q100 from NXP Semiconductors is an automotive-grade 8-channel analog switch with break-before-make switching, 0.5 Ω typical ON resistance at 2.7 V and 4.3 V supply, Schmitt-trigger digital inputs tolerant to slow edges, and 1.8 V logic compatibility in 3.3 V systems - used for signal routing in infotainment audio paths and sensor multiplexing in ADAS domain controllers.
For engineers reviewing the NX3L4051HR-Q100 datasheet, NX3L4051HR-Q100 pinout, NX3L4051HR-Q100 application, or NX3L4051HR-Q100 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), HXQFN16 thermal-enhanced package, 1.4 V to 4.3 V supply range, and bidirectional 4.3 V signal handling capability without level shifters.
Technical Context
The NX3L4051HR-Q100 implements a 1-of-8 decoder with active-low enable (E) controlling eight independent bidirectional switches between Z and Y0–Y7. Its CMOS architecture supports rail-to-rail analog signal transmission up to VCC, with break-before-make timing guaranteed by design to prevent signal shorting during channel transitions.
Schmitt-trigger inputs (S1–S3, E) provide hysteresis for noise immunity, while low-threshold logic enables direct interfacing with 1.8 V controllers even at VCC = 3.6 V. Input voltage tolerance extends beyond VCC (up to 4.6 V), and ESD protection exceeds 8 kV contact per IEC61000-4-2 on switch ports.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (typ) | 0.5 Ω at VCC = 2.7 V and 4.3 V - ensures minimal insertion loss and signal distortion in audio and sensor paths |
| Supply Voltage Range | 1.4 V to 4.3 V - supports operation across battery-supplied automotive subsystems including 1.8 V logic domains |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cockpit electronics |
| Switch Current (cont.) | ±350 mA - enables robust signal routing for high-drive sensors and audio outputs |
| Enable Propagation Delay | 19 ns typical at VCC ≥ 2.7 V - supports fast channel switching in real-time control loops |
| OFF-State Isolation | −90 dB at 100 kHz - prevents crosstalk between multiplexed sensor or audio channels |
| Charge Injection | 15 pC max at VCC = 4.3 V - minimizes glitch-induced offset in precision ADC front-ends |
Pinout & Package
HXQFN16 (SOT1039-2): plastic thermal enhanced extremely thin quad flat package, no leads, 16 terminals, body size 3 × 3 × 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Z) | Common I/O terminal | Bidirectional analog path shared across all 8 channels; handles signals up to VCC amplitude |
| 2–3, 5–8, 10–13, 15–16 (Y0–Y7) | Independent I/O terminals | Eight parallel analog switch paths; each connects to Z when selected; n.c. on pin 5 |
| 4 (E) | Enable input (active LOW) | Global disable: HIGH forces all switches into high-impedance OFF-state regardless of S1–S3 |
| 7–9 (S1–S3) | Digital select inputs | 3-bit binary address decoding Y0–Y7; Schmitt-triggered for noise immunity and slow-edge tolerance |
| 14 (VCC) | Positive supply | Power rail for analog and digital sections; also defines maximum signal swing (0 to VCC) |
| 6 (GND) | Ground reference | Common return for supply, logic, and analog paths; critical for low-noise signal integrity |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed by design (tb-m ≤ 9 ns at VCC ≥ 3.6 V) - eliminates momentary shorts during channel transitions |
| 1.8 V logic compatibility | VIH/VIL thresholds support direct drive from 1.8 V microcontrollers at VCC = 3.6 V - removes need for external level translators |
| High ESD robustness | 8 kV IEC61000-4-2 contact discharge on switch ports - protects against field-induced transients in automotive harnesses |
| Low charge injection | ≤15 pC at VCC = 4.3 V - reduces settling error and offset drift in precision analog front-ends |
| Rail-to-rail signal handling | VSW range = 0 to VCC - preserves full dynamic range of audio, sensor, and CAN FD diagnostic signals |

FAQ
What is the maximum signal voltage the NX3L4051HR-Q100 can switch?
The NX3L4051HR-Q100 supports bidirectional analog signal transmission from 0 V to VCC, with VCC rated up to 4.3 V. Absolute maximum switch voltage is VCC + 0.5 V (≤4.6 V), and the device tolerates input voltages up to 4.6 V even when VCC is lower - enabling safe interfacing with higher-voltage sources without clamping diodes. This capability is confirmed in Table 5 (Limiting Values) and Section 11 (Static Characteristics).
Does the NX3L4051HR-Q100 require external level shifters when driven by a 1.8 V microcontroller?
No, the NX3L4051HR-Q100 does not require external level shifters. Its low-threshold digital inputs accept 1.8 V logic levels directly at VCC = 3.6 V, with VIH = 1.3 V (min) and VIL = 0.5 V (max) per Table 7. This feature is explicitly stated in the General Description and validated across recommended operating conditions - eliminating translation circuitry in mixed-voltage automotive subsystems.
Is the NX3L4051HR-Q100 pin-compatible with the NX3L4051PW-Q100?
No, the NX3L4051HR-Q100 (HXQFN16, SOT1039-2) and NX3L4051PW-Q100 (TSSOP16, SOT403-1) have different pinouts and footprints. While both share identical electrical functionality and logic behavior, their physical layouts differ: e.g., Z is on pin 1 in HXQFN16 but pin 3 in TSSOP16, and GND is on pin 6 vs. pin 8. PCB redesign is required for substitution - confirmed in Figures 3 and 4 and Table 3 (Pin Description).
What is the thermal performance difference between the HXQFN16 and TSSOP16 packages?
The HXQFN16 package (NX3L4051HR-Q100) offers superior thermal dissipation: its Ptot is 250 mW at Tamb ≤ 135 °C, derating linearly above that temperature at 16.9 mW/K. In contrast, the TSSOP16 (NX3L4051PW-Q100) has a higher nominal Ptot (500 mW) but begins derating at 60 °C at 5.5 mW/K. The HXQFN16's thermal pad enables better heat transfer in space-constrained automotive modules - data sourced from Table 5 (Limiting Values) footnotes [3] and [4].
How does the NX3L4051HR-Q100 handle ESD events on its analog switch ports?
The NX3L4051HR-Q100 provides 8 kV ESD protection on switch ports per IEC61000-4-2 contact discharge testing, exceeding standard automotive requirements. Additional protection includes 7.5 kV HBM (JESD22-A114F Class 3A), 7.5 kV CDM (AEC-Q100-011 Rev B), and 200 V MM (JESD22-A115-A). These ratings are specified in Section 2 (Features and benefits) and Table 5 - ensuring robustness against assembly and field-induced transients.
