Product details

Overview

MC74HC1GU04DFT2 from onsemi is a single unbuffered CMOS inverter in SC-88A (SOT-353) package, operating from 2.0 V to 6.0 V supply, delivering ±2 mA output drive at 4.5 V, with 7 ns typical propagation delay at 5 V and 15 pF load, used for signal inversion in space-constrained logic interfaces and level-shifting circuits.

For engineers reviewing the MC74HC1GU04DFT2 datasheet, pinout, applications, or equivalent options, key selection factors include its unbuffered architecture, low input capacitance (5–10 pF), AEC-Q100 qualification, SC-88A footprint compatibility, and guaranteed operation across −55°C to +125°C industrial temperature range.

Technical Context

The MC74HC1GU04DFT2 implements a single-stage CMOS inverter without internal buffering, resulting in lower propagation delay but reduced noise margin versus buffered variants. Its symmetrical output impedance (IOH = IOL = 2 mA) ensures matched rise/fall times and balanced switching behavior under capacitive loads.

Designed for high-noise-immunity digital logic, it features balanced tPLH/tPHL delays, supports rail-to-rail input/output swing, and maintains stable operation across wide VCC (2.0–6.0 V) and temperature (−55°C to +125°C) ranges - critical for automotive body control modules and industrial sensor interface stages.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	2.0 V to 6.0 V - supports dual-supply systems and battery-powered logic interfacing without level shifters.
tPD (Typ)	7 ns at VCC = 5 V, CL = 15 pF - enables high-speed signal inversion in timing-critical paths like clock enable gating.
IOUT (Max)	±12.5 mA - sufficient to drive multiple 74HC inputs or small LED indicators directly.
VIH/VIL	VIH = 1.7 V (min @ VCC = 2.0 V); VIL = 0.3 V (max @ VCC = 2.0 V) - ensures reliable TTL/CMOS logic-level compatibility.
Operating Temp	−55°C to +125°C - qualified for under-hood automotive and industrial control environments.
Input Cap	5–10 pF - minimizes loading on preceding drivers and preserves signal integrity in high-frequency routing.
ICC (Max)	40 µA at TA = −55°C to +125°C - enables ultra-low-quiescent-power operation in always-on monitoring circuits.

Pinout & Package

MC74HC1GU04DFT2 uses the SC-88A (SOT-353) 5-pin surface-mount package (3.0 mm × 1.25 mm × 0.95 mm), optimized for high-density PCB layouts. Pin 1 is marked by a dot or beveled edge per onsemi mechanical drawing CASE 419A-02.

Pin/Terminal	Circuit Role	Design Meaning
1	GND	Ground reference for all internal circuitry; must be connected to low-impedance system ground plane.
2	NC	No-connect terminal - left unconnected per datasheet; not internally bonded or electrically active.
3	A	Inverter input - accepts CMOS/TTL-compatible logic levels; high-impedance (>10 MΩ) with ≤10 pF capacitance.
4	VCC	Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 2 mm of this pin for stable operation.
5	Y	Inverted logic output - drives downstream loads with symmetrical sourcing/sinking capability up to ±2 mA.

Key Features

Feature	Design Value
Unbuffered Inverter Architecture	Single-transistor-pair topology reduces propagation delay by ~30% vs. buffered HC-series inverters, enabling tighter timing margins.
AEC-Q100 Qualified	Qualified to Grade 1 (−40°C to +125°C) with PPAP documentation support - suitable for automotive body electronics and ADAS sensor interfaces.
Symmetrical Output Drive	IOH = IOL = 2 mA at VCC = 4.5 V ensures matched rise/fall times (<10 ns difference), minimizing pulse distortion in clock or strobe lines.
Pb-Free & RoHS Compliant	Meets J-STD-020 moisture sensitivity Level 1 and UL 94 V-0 flammability rating - compliant with global environmental and safety standards.
High Noise Immunity	Input hysteresis not specified, but VIH/VIL separation >70% of VCC across full voltage range provides robust rejection of EMI-induced glitches.

Equivalent & Alternatives

The following parts are listed as comparable options for similar unbuffered inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G04DBVR	Lower VCC range (1.65–5.5 V); 3.7 ns tPD at 3.3 V; higher ICC (10 µA typ); no AEC-Q100 qualification.	Better suited for 3.3 V portable consumer devices; lacks extended temperature and automotive qualification.	Select when optimizing for speed at 3.3 V and cost in non-automotive applications.
74AUP1G04GW,125	Ultra-low power (0.9 µA ICC max); wider VCC (0.8–3.6 V); slower tPD (12.3 ns at 3.0 V); AEC-Q100 Grade 2 qualified.	Targeted at battery-powered IoT endpoints requiring sub-µA standby current and moderate speed.	Select when ultra-low quiescent current and −40°C to +105°C operation are prioritized over speed.

Compared with SN74LVC1G04DBVR and 74AUP1G04GW,125, the MC74HC1GU04DFT2 uniquely balances 5 V compatibility, AEC-Q100 Grade 1 qualification, and 7 ns speed - making it optimal for automotive and industrial logic where supply voltage flexibility and extended temperature reliability are mandatory.

FAQ

What is the maximum operating temperature for MC74HC1GU04DFT2?

The MC74HC1GU04DFT2 is rated for operation from −55°C to +125°C, fully qualified per AEC-Q100 Grade 1 specifications. This extended range allows deployment in engine bay modules, motor drives, and other thermally demanding industrial locations where standard commercial-grade logic would fail.

Does MC74HC1GU04DFT2 support 3.3 V logic systems?

Yes, MC74HC1GU04DFT2 operates reliably at 3.3 V supply - its recommended VCC range (2.0 V to 6.0 V) includes 3.3 V, and input thresholds (VIH = 2.45 V min, VIL = 0.5 V max at VCC = 3.0 V) ensure full compatibility with 3.3 V CMOS and LVTTL logic families without level shifting.

Is MC74HC1GU04DFT2 pin-compatible with other SC-88A inverters?

MC74HC1GU04DFT2 follows the standard SC-88A pinout (GND–NC–A–VCC–Y), matching industry-standard 5-pin logic inverters such as SN74LVC1G04DBVR and 74AUP1G04GW. However, NC pin placement and marking orientation differ slightly - verify layout against onsemi CASE 419A-02 mechanical drawing before reuse.

What is the significance of the "U" in MC74HC1GU04DFT2?

The "U" in MC74HC1GU04DFT2 denotes the unbuffered version of the HC1G04 inverter - distinguishing it from buffered variants (e.g., MC74HC1G04). Unbuffered design yields lower propagation delay (7 ns vs. ~10 ns) and reduced power consumption, at the expense of slightly lower noise immunity and fan-out capability.

Can MC74HC1GU04DFT2 drive an LED directly?

MC74HC1GU04DFT2 can sink or source up to ±2 mA continuously at 4.5 V, sufficient to drive low-current indicator LEDs (e.g., 2 mA @ 1.8 V forward voltage) with appropriate series resistance. For higher-brightness LEDs or sustained current, use an external transistor driver - the IC is not rated for continuous >2 mA output.
