Product details
Overview
MC74HCU04ADR2G-Q from onsemi is a high-performance silicon-gate CMOS hex unbuffered inverter with six independent single-stage inverters, operating from 2.0 V to 6.0 V supply, delivering 10 LSTTL load drive capability and <18 ns propagation delay at 6.0 V, used in oscillator circuits, pulse shaping, and high-impedance amplification in automotive control modules.
For engineers reviewing the MC74HCU04ADR2G-Q datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, SOIC-14 pin mapping, AEC-Q100 qualification status, and real-world design guidance for timing-critical and noise-sensitive digital signal conditioning.
Technical Context
The MC74HCU04ADR2G-Q implements six identical unbuffered CMOS inverter stages with high-input impedance (>1 MΩ) and rail-to-rail output swing, enabling direct interface to CMOS, NMOS, and TTL logic families. Its unbuffered architecture supports stable oscillation in crystal and RC configurations without external feedback resistors.
Designed for automotive-grade reliability, it meets AEC-Q100 Grade 1 (–40 °C to +125 °C), features ±20 mA output drive per pin, and maintains guaranteed VIH/VIL thresholds across full temperature and voltage ranges - critical for robust level translation in engine control units and body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports wide-battery-range automotive systems (e.g., 12 V nominal with cold-crank dips to 6 V and load-dump spikes). |
| Propagation Delay (tPLH/tPHL) | 12 ns max at VCC = 6.0 V, TA ≤ 125 °C - enables precise timing in clock distribution and edge-sensitive trigger paths. |
| Output Drive | ±25 mA DC per pin - sufficient to directly drive LEDs, small relays, or fan-out to 10 LSTTL loads without buffering. |
| Input Leakage Current | ±1.0 µA max at 125 °C - ensures minimal current draw in battery-backed sleep modes and high-impedance sensing nodes. |
| Operating Temperature | –55 °C to +125 °C - qualified for under-hood and transmission-control applications per AEC-Q100 Rev G. |
| ESD Withstand | >2000 V HBM - provides robust handling during automated assembly and field service in industrial environments. |
| Power Dissipation Cap. | 15 pF per inverter - allows accurate dynamic power estimation (PD = CPD × VCC² × f) for thermal budgeting in sealed enclosures. |
Pinout & Package
MC74HCU04ADR2G-Q is housed in a Pb-free SOIC-14 (Case 751A) package with 1.27 mm pitch, 8.75 mm × 3.90 mm footprint, and 1.75 mm maximum height - compatible with standard reflow profiles and IPC-7351B land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Inverter Input (A1–A6) | CMOS-compatible inputs accepting 0–VCC logic levels; no internal pull-up/pull-down - requires external biasing for floating-state immunity. |
| 2, 4, 6, 8, 10, 12 | Inverter Output (Y1–Y6) | Push-pull CMOS outputs with rail-to-rail swing; capable of sourcing/sinking 25 mA for direct LED or gate driving. |
| 7 | GND | Primary ground reference for all six inverters; must be low-inductance connected to system ground plane to minimize switching noise coupling. |
| 14 | VCC | Single positive supply input for all inverters; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered Inverter Architecture | Enables stable crystal oscillator operation without external phase-shift networks - reduces BOM count in timing reference designs. |
| AEC-Q100 Qualified (Grade 1) | Validated for automotive use including PPAP documentation support - eliminates qualification overhead for Tier 1 suppliers. |
| High Noise Immunity | CMOS input threshold ratios (VIH ≈ 70% VCC, VIL ≈ 30% VCC) provide >1.5 V noise margin at 5 V supply - resists EMI in motor-driven subsystems. |
| Wide Supply Range Compatibility | Operates down to 2.0 V - supports integration into low-power microcontroller wake-up circuits and 3.3 V/5 V mixed-signal domains. |
| Pb-Free / RoHS Compliant | Meets EU Directive 2011/65/EU and JESD201A Class 2A - simplifies export compliance and end-of-life recycling reporting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unbuffered inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCU04DR | Same logic function and pinout; rated only to 85 °C ambient, non-automotive qualified. | Limited to commercial/industrial temperature range; not AEC-Q100 certified. | Select when operating environment stays below 85 °C and automotive PPAP is not required. |
| 74HC04D,118 | Identical pinout and AC specs; lacks −Q suffix and AEC-Q100 validation documentation. | No PPAP support or automotive change control; may require customer requalification. | Choose for cost-sensitive consumer applications where extended temperature and qualification traceability are unnecessary. |
Compared with SN74HCU04DR and 74HC04D,118, the MC74HCU04ADR2G-Q uniquely guarantees operation to +125 °C, includes full AEC-Q100 test reports, and supports controlled site-change processes - making it the only drop-in option for production automotive ECUs requiring zero-layout redesign.

FAQ
What is the maximum operating temperature for MC74HCU04ADR2G-Q?
The MC74HCU04ADR2G-Q is rated for continuous operation from –55 °C to +125 °C ambient, fully validated per AEC-Q100 Grade 1 requirements. This specification is confirmed in the Recommended Operating Conditions table of the official onsemi datasheet (Rev. 9, February 2024), and applies to the SOIC-14 package under natural convection conditions with proper PCB thermal relief.
Does MC74HCU04ADR2G-Q support 3.3 V logic systems?
Yes, MC74HCU04ADR2G-Q operates reliably at 3.3 V supply, with guaranteed VIH = 2.2 V min and VIL = 0.8 V max at 25 °C - providing >1.1 V noise margin. Its 2.0–6.0 V supply range makes it interoperable with both 3.3 V microcontrollers and legacy 5 V peripherals without level shifters.
Is MC74HCU04ADR2G-Q pin-compatible with LS04 logic devices?
Yes, MC74HCU04ADR2G-Q has identical pinout to the 74LS04 and MC14069UB, as explicitly stated in the onsemi datasheet introduction. All six inverter inputs (pins 1,3,5,9,11,13) and outputs (pins 2,4,6,8,10,12) align, with VCC on pin 14 and GND on pin 7 - enabling direct replacement in existing LS04 layouts.
What oscillator configurations are supported by MC74HCU04ADR2G-Q?
MC74HCU04ADR2G-Q supports crystal oscillator (Figure 5), stable RC oscillator (Figure 6), and Schmitt-trigger configurations (Figure 7) as documented in the onsemi datasheet. Its unbuffered design and low input capacitance (10 pF) enable reliable startup and low-jitter operation with quartz crystals up to 20 MHz and RC time constants from 100 ns to 10 ms.
How does the −Q suffix affect MC74HCU04ADR2G-Q's manufacturing process?
The −Q suffix on MC74HCU04ADR2G-Q denotes dedicated automotive production flow: AEC-Q100 stress testing, PPAP documentation, unique site and change control procedures, and enhanced traceability per lot code (e.g., AWLYWW format). This ensures consistent parametric performance and failure-mode coverage across automotive production lots - distinct from commercial-grade variants.
