Product details
Overview
74AHCU04D,112 from Nexperia is a hex unbuffered inverter IC operating at 2V–6V supply, with 8.5ns typical propagation delay at 5V, ±8mA output drive, and CMOS-compatible input thresholds. It serves as a signal-level logic inverter in digital interface translation and clock conditioning circuits within industrial control modules.
For engineers reviewing the 74AHCU04D,112 datasheet, 74AHCU04D,112 pinout, 74AHCU04D,112 application, or 74AHCU04D,112 equivalent, key selection criteria include propagation delay matching, rail-to-rail input compatibility, output current capability for fanout, and SO14 package thermal performance in high-density PCB layouts.
Technical Context
This device implements six independent CMOS inverter gates with unbuffered (non-schmitt-trigger) inputs, enabling precise edge timing without hysteresis. Its low dynamic power consumption (0.5µA ICC at 25°C, VCC = 5V) and rail-to-rail input voltage range support mixed-voltage system interfacing.
The 74AHCU04D,112 uses silicon-gate CMOS technology to achieve high noise immunity (400mV minimum VIH–VIL margin at VCC = 4.5V) and symmetrical rise/fall times (typ. 7.5ns at CL = 50pF, VCC = 5V), critical for clean signal inversion in synchronous logic paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0V to 6.0V - supports direct interface with 3.3V and 5V logic families without level shifters |
| Propagation Delay | 8.5ns @ VCC=5V, CL=50pF - enables reliable operation up to ~35MHz toggle frequency in non-critical timing paths |
| Output Drive | ±8mA @ VCC=5V - sufficient to drive 10 LS-TTL loads or two 74HC-series inputs with margin |
| Input Threshold | VIL ≤ 1.5V, VIH ≥ 3.5V @ VCC=5V - ensures robust recognition of 3.3V logic-high signals in mixed-supply systems |
| Quiescent Current | 0.5µA @ 25°C - minimizes static power in battery-backed or always-on monitoring subsystems |
| Operating Temp | −40°C to +125°C - qualified for under-hood automotive and industrial motor-control environments |
Pinout & Package
Supplied in a 14-pin SOIC (SO14) package with standard 1.27mm pitch, JEDEC MS-012AC compliant, body width 3.9mm, and thermal resistance θJA = 130K/W on 2-layer FR4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input A–F | CMOS-compatible unbuffered inputs accepting 0–VCC logic levels |
| 2, 4, 6, 8, 10, 12 | Output Y1–Y6 | Inverted outputs capable of sourcing/sinking ±8mA at VCC=5V |
| 7 | GND | Digital ground reference for all internal logic and I/O |
| 14 | VCC | Primary power supply pin; decoupling capacitor required within 5mm |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered Inverter Architecture | Eliminates hysteresis for precise timing alignment in clock distribution and data strobing |
| Rail-to-Rail Input Compatibility | Accepts logic-low down to 0V and logic-high up to VCC, enabling direct connection to analog switches or DAC outputs |
| High Noise Immunity | Guaranteed 400mV input noise margin at VCC=4.5V, reducing susceptibility to crosstalk in dense routing |
| Low Dynamic Power | Typical ICC of 0.5µA at standby eliminates need for power gating in always-on sensor nodes |
Applications
| Industrial PLC I/O Conditioning | Automotive Body Control Module |
|---|---|
Use Scenario: Inverting sensor status signals (e.g., door open/closed) before feeding into microcontroller GPIOs with weak pull-ups. IC Role / Device Role / Timing Role: Signal polarity correction with minimal propagation delay to preserve real-time response. Use Value: Eliminates software inversion overhead and ensures deterministic timing for safety-critical state detection. | Use Scenario: Driving LED indicators and small solenoid drivers via discrete transistor bases in dashboard lighting control. IC Role / Device Role / Timing Role: Logic-level translation and current gain stage between MCU outputs and external loads. Use Value: Provides ±8mA drive directly-reducing component count versus using dedicated buffer transistors. |
| Test Equipment Signal Generation | Medical Device Isolated Interface |
Use Scenario: Generating complementary clock edges for dual-edge sampling in portable oscilloscope front-end ASICs. IC Role / Device Role / Timing Role: Low-skew inverter for creating true/complement pairs without added jitter. Use Value: 8.5ns delay matching across channels maintains <1ns skew between inverted/non-inverted paths. | Use Scenario: Level-shifting isolated UART TX/RX lines between 3.3V MCU and 5V optocoupler inputs in patient-monitoring units. IC Role / Device Role / Timing Role: Bidirectional logic-level translator with no direction control pin required. Use Value: Rail-to-rail input thresholds allow reliable recognition of 3.3V logic-high even with 5V VCC, simplifying isolation design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unbuffered inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC04APW | Lower VCC range (1.65–5.5V); 3.5ns delay @ 3.3V; 24mA drive | Better suited for high-speed 3.3V-only systems; not rated for 6V operation | Select when speed >8MHz and VCC ≤ 5.5V; avoid if 6V tolerance or 125°C operation required |
| 74HC04D,653 | Higher ICC (4µA quiescent); 15ns delay @ 5V; same SO14 package | Higher static power and slower switching limit use in ultra-low-power or high-frequency designs | Acceptable for cost-sensitive 5V legacy systems where 8.5ns delay is non-critical |
Compared with SN74LVC04APW and 74HC04D,653, the 74AHCU04D,112 uniquely balances 6V tolerance, sub-10ns delay, and µA-level quiescent current-making it optimal for mixed-voltage industrial nodes requiring long-term reliability at temperature extremes.

FAQ
What is the maximum recommended capacitive load for stable operation of the 74AHCU04D,112?
The device is characterized up to 50pF load capacitance per output, with guaranteed timing and drive performance. Exceeding 50pF increases propagation delay nonlinearly and may cause ringing; for >50pF loads, add series termination or reduce trace length to maintain signal integrity.
Does the 74AHCU04D,112 support hot insertion or live insertion into powered systems?
No-this device lacks hot-swap protection circuitry. Applying VCC before or after input signals may cause latch-up due to internal parasitic SCR structures. Always power VCC first and ensure inputs remain within 0–VCC during power-up/down sequencing.
Can the 74AHCU04D,112 be used as an oscillator by connecting output to input?
Yes, but only in non-critical applications: the unbuffered inverter enables ring oscillation when configured with external RC feedback, yielding frequencies from kHz to low MHz depending on load and supply. However, frequency stability and duty cycle are not specified or guaranteed.
Is the 74AHCU04D,112 RoHS-compliant and halogen-free?
Yes-the 74AHCU04D,112 meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21, with bromine and chlorine content each below 900 ppm, verified through material declaration and third-party testing.
