Product details
Overview
MC74HCU04ADTR2G-Q from onsemi is a high-performance silicon-gate CMOS hex unbuffered inverter IC, providing six independent single-stage inverters in a TSSOP-14 package. It operates from 2.0 V to 6.0 V, delivers 10 LSTTL load drive capability, exhibits ≤10 pF input capacitance and ≤15 pF power dissipation capacitance per inverter, and supports automotive applications with AEC-Q100 qualification and PPAP capability.
For engineers reviewing the MC74HCU04ADTR2G-Q datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated pin mapping, confirmed automotive-grade qualification status, real-world oscillator and Schmitt-trigger use cases, and two technically documented alternative parts for design flexibility.
Technical Context
The MC74HCU04ADTR2G-Q implements six identical unbuffered CMOS inverters with high-input impedance and rail-to-rail output swing. Each inverter features symmetrical propagation delays (tPLH/tPHL ≤18 ns at VCC = 4.5 V, TA ≤85°C) and fast transition times (tTLH/tTHL ≤19 ns under same conditions), enabling stable oscillation in crystal and RC configurations.
Its input compatibility spans standard CMOS outputs and, with pullup resistors, LSTTL outputs; output drive meets 10 LSTTL loads while maintaining low ICC (≤40 µA at VCC = 6.0 V, TA ≤125°C) and ultra-low input leakage (±1.0 µA). The device complies with JEDEC Std 7.0A and supports operation from –55°C to +125°C.
Key Specifications

| Propagation Delay (max) | 18 ns @ VCC = 4.5 V, TA ≤85°C - Supports >25 MHz fundamental oscillation frequency in ring oscillator topologies. |
| Input Capacitance (max) | 10 pF - Minimizes loading on preceding stage; critical for high-frequency clock buffer and waveform shaping. |
| Output Drive | 10 LSTTL loads - Sufficient to drive multiple legacy TTL inputs without external buffers. |
| Operating Temperature | –55°C to +125°C - Validated for under-hood automotive electronics and industrial control environments. |

Key Features
| Feature | Design Value |
|---|---|
| Unbuffered inverter architecture | Enables precise phase inversion with minimal internal delay skew-essential for crystal oscillator feedback loops. |
| High noise immunity | CMOS threshold symmetry (VIH/VIL ratio ~3:1 at VCC = 5 V) rejects transient coupling in noisy automotive harnesses. |

| Chip complexity | 12 FETs / 3 equivalent gates per inverter-minimizes static current (ICC ≤1 µA @ VCC = 6.0 V, TA = 25°C) and thermal footprint. |
| Pb-free, halogen-free packaging | Complies with J-STD-020 moisture sensitivity level 1-enables standard reflow without baking or special handling. |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|

IC Role / Device Role / Timing Role: Unbuffered inverter operating in linear region as gain element in Pierce oscillator topology. Use Value: Guaranteed oscillation stability across –40°C to +85°C due to symmetric tPLH/tPHL and low ICC drift (≤10 µA over temperature). |
Use Scenario: Driving discrete red/green dual-color LEDs from MCU GPIO pins with inverted logic polarity. IC Role / Device Role / Timing Role: Logic-level translator and current sink driver (IOUT = –5.2 mA max) for common-anode LED configuration. Use Value: VOL ≤0.32 V @ –4.0 mA ensures >2.0 V forward bias margin for standard 2.1 V red LEDs at 5 V supply. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex unbuffered inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCU04PWR | TSSOP-14, non-automotive grade; no AEC-Q100 qualification; ICC max = 20 µA @ 125°C (vs. 40 µA for MC74HCU04ADTR2G-Q). | Limited to commercial/industrial temperature range (–40°C to +85°C); not PPAP-capable. | Select when automotive qualification is unnecessary and lower quiescent current is prioritized. |
| 74HCU04D,118 | SOT338-1 (SO-14) package; same electrical specs but different mechanical footprint; MSL Level 1 vs. Level 3 for TSSOP variant. | Requires PCB layout change; unsuitable for space-constrained automotive modules where TSSOP-14 is specified. | Choose only if SOIC-14 is mandated by legacy board design or procurement constraints. |
Compared with SN74HCU04PWR and 74HCU04D,118, the MC74HCU04ADTR2G-Q uniquely combines AEC-Q100 qualification, full –55°C to +125°C operation, and TSSOP-14 packaging-making it the sole option for new automotive designs requiring drop-in compliance and thermal robustness without layout revision.

FAQ
What is the maximum operating temperature for MC74HCU04ADTR2G-Q?
The MC74HCU04ADTR2G-Q is rated for continuous operation from –55°C to +125°C. This full automotive temperature range is validated per AEC-Q100 stress test requirements and confirmed in the Recommended Operating Conditions table of the official datasheet. The device maintains guaranteed VOH/VOL and propagation delay performance across this entire span, making MC74HCU04ADTR2G-Q suitable for engine control units and under-hood modules.
Does MC74HCU04ADTR2G-Q support 2.5 V logic systems?
Yes, MC74HCU04ADTR2G-Q fully supports 2.5 V operation: its recommended supply range is 2.0 V to 6.0 V, and all DC and AC specifications-including VIH (≥1.7 V), VOL (≤0.32 V @ 2.4 mA), and tPLH/tPHL (≤45 ns)-are guaranteed at VCC = 2.5 V. This enables direct interfacing with 2.5 V FPGA I/O banks and low-voltage microcontrollers without level translation.
Is MC74HCU04ADTR2G-Q pin-compatible with LS04 or MC14069UB?
Yes, MC74HCU04ADTR2G-Q is identical in pinout to both the 74LS04 and MC14069UB, as explicitly stated in the datasheet's first paragraph. Pin assignments for inputs (A1–A6), outputs (Y1–Y6), VCC (pin 14), and GND (pin 7) match exactly-enabling drop-in replacement in legacy designs originally using those families, provided voltage and speed requirements align.
Can MC74HCU04ADTR2G-Q be used to build a crystal oscillator?
Yes, MC74HCU04ADTR2G-Q is explicitly recommended for crystal oscillator use in Figures 5 and 6 of the datasheet. Its unbuffered architecture, low input capacitance (10 pF), and guaranteed oscillation capability down to 2.5 V make it ideal for Pierce oscillator configurations with 32.768 kHz tuning forks or MHz-range AT-cut crystals-common in automotive real-time clocks and remote keyless entry transmitters.
What does the "−Q" suffix signify in MC74HCU04ADTR2G-Q?
The "−Q" suffix in MC74HCU04ADTR2G-Q denotes automotive-grade qualification: the device is AEC-Q100 qualified, PPAP capable, and manufactured under controlled site and change management protocols required for automotive production. This includes enhanced traceability, lot-level documentation, and failure rate validation beyond commercial-grade variants like MC74HCU04ADTR2G.
