Product details
Overview
MC74HC1GU04DBVT1G from onsemi is a single unbuffered CMOS inverter in SC-74A (SOT-23-5) 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 interface and level-shifting circuits.
For engineers reviewing the MC74HC1GU04DBVT1G datasheet, pinout, applications, or equivalent options, key selection criteria include unbuffered inverter topology, SC-74A thermal resistance (320°C/W), −55°C to +125°C operating range, and AEC-Q100 qualification for automotive subsystems.
Technical Context
The MC74HC1GU04DBVT1G implements a single-stage CMOS inverter without internal buffering, resulting in lower propagation delay but reduced noise margin compared to buffered variants. Its symmetrical output impedance (IOH = IOL = 2 mA) ensures matched rise/fall times and balanced tPLH/tPHL performance.
It supports rail-to-rail input and output operation across 2.0–6.0 V VCC, with VIH/VIL thresholds scaling proportionally to supply voltage. Input leakage remains ≤±1.0 µA over full temperature range, enabling low-power standby in battery-operated sensor nodes and microcontroller GPIO conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 6.0 V - Enables direct interfacing with 3.3 V and 5 V logic families without level shifters. |
| tPD (Typ) | 7 ns at VCC = 5 V, CL = 15 pF - Supports >100 MHz toggle rates in short-path digital timing applications. |
| IOUT (Max) | ±12.5 mA - Sufficient to drive multiple 74HC inputs or small capacitive loads (<50 pF) without external buffers. |
| Operating Temp | −55°C to +125°C - Qualified for under-hood automotive, industrial control, and extended-temperature embedded systems. |
| ESD Rating | HBM: 2000 V - Provides robust handling during PCB assembly and field service without special ESD precautions. |
| Package | SC-74A (SOT-23-5), 3.00 × 1.50 × 0.95 mm - Fits high-density layouts where board area is constrained, e.g., wearables and IoT edge nodes. |
| Quiescent ICC | 1.0 µA max at VCC = 6.0 V, TA = 25°C - Minimizes static power in always-on monitoring circuits. |
Pinout & Package
MC74HC1GU04DBVT1G uses the SC-74A (SOT-23-5) package - a 5-pin, surface-mount, lead-free, RoHS-compliant outline with 0.95 mm pitch and exposed pad not present. Pin 1 is marked by a dot or beveled edge per JEDEC MO-178.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry; must be connected to system ground plane for stable logic thresholds and EMI suppression. |
| 2 | NC | No-connect terminal - left unconnected per datasheet; floating or tied to GND/VCCT has no functional impact. |
| 3 | A | Inverter input - accepts CMOS-compatible logic levels; VIH ≥ 1.7 V @ VCC = 2.0 V, VIL ≤ 0.3 V @ same condition. |
| 4 | VCC | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 2 mm for reliable AC performance. |
| 5 | Y | Inverted output - provides true complement of input A; VOL ≤ 0.1 V @ IOL = 2 mA, VOH ≥ 4.0 V @ IOH = −2 mA @ VCC = 4.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered architecture | Reduces gate delay by eliminating internal buffer stages, enabling tighter timing closure in critical path logic inversion. |
| Balanced propagation delays | tPLH = tPHL (typical) - Ensures symmetrical waveform edges, minimizing duty cycle distortion in clock inversion or pulse shaping. |
| High noise immunity | VIH − VIL ≥ 1.4 V @ VCC = 4.5 V - Tolerates >300 mV of coupled noise on input lines without false triggering. |
| AEC-Q100 qualified | Grade 1 (−40°C to +125°C) with PPAP capability - Validated for use in automotive body electronics, infotainment, and ADAS sensor interfaces. |
| Pb-free, Halogen-free | Meets RoHS Directive 2011/65/EU and JESD201A Class 2 - Compliant with environmental regulations for global OEM production. |

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); higher drive (±32 mA); 3.5 ns tPD @ 3.3 V. | Better suited for 1.8 V/3.3 V mixed-signal systems; not rated for 6 V operation or −55°C. | Select when higher speed and 3.3 V compatibility outweigh extended temperature and voltage range needs. |
| 74AUP1G04GW,125 | Ultra-low power (ICC = 0.9 µA max); wider temp range (−40°C to +125°C); slower (11 ns tPD @ 3.3 V). | Optimized for battery-powered IoT endpoints; lacks AEC-Q100 qualification and 6 V tolerance. | Prefer for energy-constrained designs where 7 ns speed is unnecessary and automotive qualification is not required. |
Compared with SN74LVC1G04DBVR and 74AUP1G04GW,125, the MC74HC1GU04DBVT1G uniquely combines 6 V operation, −55°C capability, and AEC-Q100 qualification - making it the only choice for automotive-grade, wide-supply, extended-temperature unbuffered inversion.

FAQ
What is the maximum supply voltage rating for MC74HC1GU04DBVT1G?
The MC74HC1GU04DBVT1G supports a maximum DC supply voltage of +6.0 V for SC-74A package variants. Exceeding this limit risks permanent damage per the Absolute Maximum Ratings table. Operation above 6.0 V is not guaranteed, even briefly, and violates JEDEC stress guidelines.
Does MC74HC1GU04DBVT1G have a defined pin 2 function?
Pin 2 of the MC74HC1GU04DBVT1G is explicitly designated as NC (No Connect) in the official datasheet pin assignment diagram and ordering information. It must remain unconnected - neither grounded nor tied to VCC - to ensure correct device behavior and avoid undefined states.
Is MC74HC1GU04DBVT1G suitable for automotive applications?
Yes, MC74HC1GU04DBVT1G is AEC-Q100 qualified (Grade 1) and PPAP capable, with full characterization from −55°C to +125°C. It is approved for use in non-safety-critical automotive subsystems including door modules, lighting controls, and body ECUs where unbuffered inversion is required.
What is the typical propagation delay of MC74HC1GU04DBVT1G at 3.3 V?
At VCC = 3.0 V and CL = 50 pF, the MC74HC1GU04DBVT1G exhibits a typical propagation delay of 9 ns (tPLH/tPHL). This value is confirmed in the AC Electrical Characteristics table and reflects real-world performance with moderate capacitive loading common in PCB traces and input gates.
How does the unbuffered design of MC74HC1GU04DBVT1G affect its noise immunity?
The unbuffered architecture of MC74HC1GU04DBVT1G results in slightly lower noise margins than buffered inverters - VIH − VIL is ~1.4 V at 4.5 V, versus ~2.0 V for buffered HC variants. However, its high noise immunity is maintained via optimized threshold design and rail-to-rail input hysteresis, meeting industrial EMC requirements.
