Product details
Overview
74LVU04D,112 from NXP Semiconductors is a low-voltage Si-gate CMOS hex unbuffered inverter with pin-and-function compatibility to 74HCU04. It operates across 1.0 V to 5.5 V, delivers propagation delays as low as 6 ns at 3.3 V/15 pF, and supports industrial temperature range (−40 °C to +125 °C) in SO14 package. It serves as a core logic element in crystal oscillator feedback paths and linear amplifier stages.
For engineers reviewing the 74LVU04D,112 datasheet, 74LVU04D,112 pinout, 74LVU04D,112 application, or 74LVU04D,112 equivalent, this page provides verified electrical parameters, SO14 package terminal mapping, oscillator design guidance, and validated alternative options for unbuffered inverter-based timing and signal conditioning circuits.
Technical Context
The 74LVU04D,112 implements six independent single-stage CMOS inverters with unbuffered outputs-no internal gain staging or output drive enhancement. Its transfer characteristics exhibit sharp switching thresholds optimized for stable oscillation startup and low-noise linear amplification when biased in the transition region.
It features rail-to-rail input voltage tolerance (0 V to VCC), guaranteed operation down to 1.0 V supply, and ESD protection exceeding 2000 V HBM. Output drive capability is specified up to ±12 mA at 4.5 V, with ground bounce < 0.8 V and VOH undershoot > 2 V under 3.3 V/25 °C conditions.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A, 5A, 6A | Input of inverter n | CMOS-compatible digital input; accepts 0 V to VCC; no internal pull-up/down; requires external bias for linear operation. |

Key Features
| Feature | Design Value |
|---|---|

| Industrial temperature grade | Validated performance over full −40 °C to +125 °C range ensures reliability in engine control units, power converters, and base station radios. |
Applications
| Crystal Oscillator | Linear Amplifier |
|---|---|
Use Scenario: Generating stable clock signals for microcontrollers using a parallel-resonant AT-cut quartz crystal (e.g., 1–20 MHz). IC Role / Device Role / Timing Role: Provides 180° phase inversion and gain in a three-point Pierce configuration with two external load capacitors. Use Value: Unbuffered architecture enables predictable loop gain control; propagation delay and input capacitance (3.5 pF) are tightly specified to ensure reliable startup and frequency stability. |
Use Scenario: Building low-noise, wideband AC-coupled amplifiers for sensor signal conditioning (e.g., piezoelectric transducers, microphone preamps). IC Role / Device Role / Timing Role: Operated in linear region via DC bias network (R1/R2) to deliver voltage gain with minimal harmonic distortion. Use Value: Typical unity-gain bandwidth of 5 MHz and open-loop gain of 20 allow stable amplification up to ~100 kHz with external compensation; low input leakage preserves high-impedance node integrity. |
| Astable Multivibrator | Waveform Shaping |
Use Scenario: Generating square-wave clock or timing signals for LED flashers, PWM dimming, or simple state machines without external timers. IC Role / Device Role / Timing Role: Forms RC-delayed feedback loop with two inverters to produce free-running oscillation. Use Value: Propagation delay variation < ±1 ns across temperature ensures consistent duty cycle; low output impedance maintains waveform edge integrity into 10 kΩ loads. |
Use Scenario: Converting slow or noisy digital edges (e.g., from mechanical switches, optocouplers, or long traces) into clean, fast-rising/falling logic signals. IC Role / Device Role / Timing Role: Acts as Schmitt-trigger-like signal conditioner by exploiting input hysteresis inherent in CMOS transfer curve. Use Value: Input threshold symmetry (VIH ≈ 0.5VCC) and low input capacitance (3.5 pF) minimize jitter accumulation; rail-to-rail output swing ensures TTL/CMOS compatibility. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unbuffered inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC04PW,118 | Buffered output stage; higher drive (±24 mA); lower propagation delay (4.1 ns @ 3.3 V); same SO14 package. | Not suitable for crystal oscillator feedback due to added phase shift; better for fanout-heavy logic translation. | Select when high-speed logic buffering is needed-not for linear or oscillator use. |
| SN74LV04APW | TI variant; identical unbuffered architecture; slightly higher ICC (max 40 μA vs. 20 μA); same SO14 footprint. | Valid drop-in replacement in most oscillator and multivibrator designs; minor quiescent current difference affects battery life in always-on sensors. | Prefer for TI-centric BOMs; verify layout clearance for thermal pad if used in DHVQFN variant. |
Compared with 74LVU04D,112, the 74LVC04PW,118 offers superior speed and drive but sacrifices oscillator stability due to buffering, while SN74LV04APW provides functional equivalence with marginal ICC trade-off-making it the closest direct alternative for legacy 74LVU04 designs.

FAQ
What is the maximum operating frequency of the 74LVU04D,112 in a crystal oscillator circuit?
The 74LVU04D,112 supports fundamental-mode crystal oscillators up to approximately 30 MHz, based on its 6 ns typical propagation delay at 3.3 V and 15 pF load. Actual frequency depends on crystal parameters (ESR, load capacitance), external resistor values (R1/R2), and PCB layout parasitics. For frequencies above 20 MHz, careful attention to grounding and trace length is required to maintain loop stability.
Can the 74LVU04D,112 be used as a linear amplifier, and what biasing is required?
Yes, the 74LVU04D,112 can operate linearly when DC-biased in its transition region using resistive feedback (e.g., R1 = 1–10 MΩ, R2 = 47 kΩ–220 kΩ). The datasheet specifies typical open-loop gain of 20 and unity-gain bandwidth of 5 MHz. Biasing must center the input at ~0.5VCC; output swing is limited to VCC − 1.5 V peak-to-peak centered at 0.5VCC.
Does the 74LVU04D,112 have built-in ESD protection, and what levels are guaranteed?
Yes, the 74LVU04D,112 includes on-chip ESD protection rated per JESD22 standards: Human Body Model (HBM) > 2000 V and Machine Model (MM) > 200 V. This meets typical board-level handling requirements and reduces need for external TVS diodes in non-harsh environments, though system-level protection remains recommended for field-deployed equipment.
Is the 74LVU04D,112 pin-compatible with the 74HCU04, and are there any design considerations?
Yes, the 74LVU04D,112 is explicitly pin- and function-compatible with the 74HCU04. However, its lower supply voltage range (1.0–5.5 V vs. 2.0–6.0 V) and unbuffered output require verification of drive strength and noise margins in legacy 74HCU04 designs-especially at VCC < 2.0 V or when driving heavy capacitive loads (>30 pF).
What is the input capacitance of the 74LVU04D,112, and why does it matter in oscillator design?
The 74LVU04D,112 has a typical input capacitance of 3.5 pF. In crystal oscillator circuits, this value directly contributes to the total capacitive load seen by the crystal, affecting frequency accuracy and stability. Designers must subtract this 3.5 pF from the target load capacitance (e.g., 12 pF or 18 pF) when selecting external load capacitors to meet crystal manufacturer specifications.
