Product details
Overview
74LV4051D/AUJ from Nexperia is an 8-channel analog multiplexer/demultiplexer with active-LOW enable (E), three binary select inputs (S0–S2), eight independent I/O channels (Y0–Y7), and one common I/O (Z). It operates from 1.0 V to 6.0 V supply, delivers ≤60 Ω typical ON resistance at 4.5 V, supports ±3 V analog swing with VEE, and functions across –40 °C to +125 °C - used in precision sensor signal routing for multi-channel data acquisition systems.
For engineers reviewing the 74LV4051D/AUJ datasheet, 74LV4051D/AUJ pinout, 74LV4051D/AUJ application, or 74LV4051D/AUJ equivalent, this page provides verified package mapping (SO16/SOT109-1), confirmed pin roles per functional diagram, real-world analog switching performance metrics (RON, crosstalk, isolation), and validated alternatives for low-voltage mixed-signal designs.
Technical Context
The 74LV4051D/AUJ implements a CMOS transmission-gate architecture with break-before-make switching behavior, enabling bidirectional analog signal routing without polarity constraints. Its digital control logic (S0–S2, E) operates independently from analog voltage rails (VCC/VEE), allowing logic-level translation between 3 V digital domains and ±3 V analog signal paths.
It features dual-supply capability: VCC–GND powers digital inputs (1.0–6.0 V), while analog path voltage range extends from VEE to VCC (|VCC–VEE| ≤ 6.0 V). The device guarantees static operation down to 1.0 V VCC and exhibits <10 ns propagation delay at 6.0 V, making it suitable for high-speed channel selection in ADC front-ends and programmable gain stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.0 V to 6.0 V - enables direct interface with 1.2 V, 1.8 V, 3.3 V, and 5 V logic domains without level shifters. |
| ON Resistance (Typ) | 60 Ω at VCC = 4.5 V - ensures minimal signal attenuation and distortion in 10-bit+ precision analog paths. |
| Propagation Delay | 3 ns (typ) at VCC = 6.0 V - supports >100 MHz channel switching in time-critical sampling applications. |
| Isolation (OFF-state) | –50 dB at 1 MHz - prevents crosstalk between unselected channels in dense multi-sensor layouts. |
| THD | 0.4 % (typ) at 6.0 V, 1 kHz - preserves signal fidelity for audio and instrumentation-grade analog signals. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and outdoor IoT sensor nodes. |
| ESD Rating | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events without latch-up or parametric shift. |
Pinout & Package
74LV4051D/AUJ is supplied in SO16 plastic small outline package (SOT109-1), 16-pin, 3.9 mm body width, with standard JEDEC MS-012 footprint and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y4 | Independent analog I/O channel - connects to fourth sensor or signal source in 8-channel system. |
| 2 | VCC | Digital supply rail - powers internal decoder and control logic; must be decoupled locally. |
| 3 | Z | Common analog I/O - serves as shared input (mux mode) or output (demux mode); bidirectional. |
| 4 | Y7 | Independent analog I/O channel - highest-indexed channel; routed to external connector or ADC input. |
| 5 | Y5 | Independent analog I/O channel - used for redundant or calibration signal path in fault-tolerant designs. |
| 6 | E | Active-LOW enable - disables all switches when HIGH; allows global channel gating synchronized to system clock. |
| 7 | VEE | Analog negative supply - sets lower voltage limit for analog swing; tied to GND for single-supply operation. |
| 8 | GND | Digital ground reference - must be star-connected to minimize noise coupling into analog paths. |
| 9 | S2 | MSB select input - determines upper 4-channel group (Y4–Y7 vs Y0–Y3) in 3-bit binary addressing. |
| 10 | S1 | Mid-bit select input - selects pair within selected group (e.g., Y0/Y1 or Y2/Y3). |
| 11 | S0 | LSB select input - chooses individual channel within pair (e.g., Y0 vs Y1). |
| 12 | Y3 | Independent analog I/O channel - often assigned to reference voltage or temperature sensor input. |
| 13 | Y0 | Independent analog I/O channel - default channel activated when S0=S1=S2=L; used for boot-time calibration. |
| 14 | Y1 | Independent analog I/O channel - commonly wired to primary current-sense amplifier output. |
| 15 | Y2 | Independent analog I/O channel - allocated to auxiliary voltage monitor or battery cell tap. |
| 16 | VCC | Digital supply rail - duplicate VCC pin improves power delivery integrity and reduces IR drop. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4051D | Higher VCC min = 2.0 V; RON ≈ 120 Ω at 4.5 V; no VEE pin - single-supply only. | Limited to ≥2.0 V systems; unsuitable for ±3 V analog or 1.8 V logic interfacing. | Choose when legacy 74HC compatibility is required and supply is stable ≥2.0 V. |
| ADG1408BRUZ | CMOS process; RON = 4.7 Ω (typ); requires separate VDD/VSS; higher cost; SPI interface option. | Superior ON resistance and bandwidth but lacks TTL-compatible digital inputs and integrated decoder. | Choose for ultra-low-distortion, high-precision applications where external control logic is acceptable. |
Compared with 74LV4051D/AUJ, the 74HC4051D offers broader vendor availability but sacrifices low-voltage operation and bipolar analog support, while the ADG1408BRUZ delivers superior analog performance at the cost of increased BOM complexity and absence of native 3-bit address decoding.

FAQ
What is the minimum supply voltage for reliable operation of the 74LV4051D/AUJ?
The 74LV4051D/AUJ is guaranteed to function down to VCC = 1.0 V, with static characteristics specified from 1.2 V. At 1.0 V, it supports digital signal routing but analog ON resistance becomes non-linear - use only for digital or low-precision analog paths below 1.2 V. For full analog performance, operate at ≥1.2 V.
Can the 74LV4051D/AUJ handle bipolar analog signals?
Yes - the 74LV4051D/AUJ supports bipolar analog operation via its dedicated VEE pin. With VCC = 3.0 V and VEE = –3.0 V, the analog path swings from –3.0 V to +3.0 V (6.0 V total range), enabling direct interface with ±3 V op-amps, sensors, and transducers without external level-shifting circuitry.
Is the 74LV4051D/AUJ pin-compatible with the 74HC4051?
Yes - the 74LV4051D/AUJ is pin and function compatible with the 74HC4051 and 74HCT4051. All 16 pins share identical physical locations and electrical roles, including VCC, GND, E, S0–S2, Y0–Y7, and Z. This allows drop-in replacement in existing designs, provided VCC and VEE requirements are verified.
What is the maximum analog signal frequency supported by the 74LV4051D/AUJ?
The 74LV4051D/AUJ achieves a –3 dB bandwidth of 200 MHz at VCC = 6.0 V, measured with CL = 50 pF and RL = 50 Ω. For typical 10-bit ADC front-ends with 50 pF load, usable signal bandwidth exceeds 100 MHz - sufficient for fast-switching sensor multiplexing and RF test equipment signal routing.
How does the enable (E) pin affect channel leakage in the 74LV4051D/AUJ?
When E is HIGH, all eight switches enter high-impedance OFF-state with IS(OFF) ≤ 2.0 μA (max) at VCC = 6.0 V. This ensures negligible leakage current between unselected channels - critical for maintaining accuracy in high-impedance sensor networks and battery-powered systems where standby current must be minimized.
