Product details
Overview
MC74VHC1GU04DFT1 from onsemi is a single unbuffered CMOS inverter optimized for high-speed logic inversion in space-constrained applications. It operates from 2.0 V to 5.5 V, delivers 2.5 ns typical propagation delay at 5 V, tolerates input voltages up to 5.5 V independent of supply, and supports 8 mA output drive at 3.0 V - enabling level-shifting between 3 V and 5 V digital subsystems.
For engineers reviewing the MC74VHC1GU04DFT1 datasheet, pinout, applications, or equivalent options, key selection criteria include unbuffered gate response, overvoltage-tolerant inputs, IOFF partial power-down capability, SC-88A package footprint, and compatibility with oscillator and pulse-shaping circuits requiring low-input-capacitance inversion.
Technical Context
The MC74VHC1GU04DFT1 implements a single unbuffered inverter stage using advanced CMOS process technology, eliminating internal buffering to minimize propagation delay and input-to-output phase shift. Its input structure incorporates overvoltage protection diodes rated to 5.5 V, allowing safe interfacing with higher-voltage logic domains without external clamping.
IOFF functionality ensures input leakage remains below 10 µA when VCC = 0 V, supporting live insertion and partial power-down system architectures. The device exhibits 4.0 pF typical input capacitance and 22.0 pF power dissipation capacitance, confirming suitability for high-frequency clock conditioning and clean signal edge generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - enables direct operation across 3.3 V and 5 V logic rails without level translators |
| tPD (Typ) | 2.5 ns at 5 V, CL = 15 pF - supports >300 MHz toggle rates in oscillator or timing feedback loops |
| VIN Tolerance | Up to 5.5 V regardless of VCC - permits safe connection to 5 V inputs while powered from 3 V |
| IOFF Leakage | <10 µA at VIN = 5.5 V, VCC = 0 V - prevents back-driving during hot-swap or power sequencing |
| IOUT Drive | ±8 mA at 3.0 V - sufficient to drive multiple 74VHC inputs or small capacitive loads (≤30 pF) |
| CIN (Typ) | 4.0 pF - minimizes loading on preceding driver stages in high-speed signal chains |
| Operating Temp | −55 °C to +125 °C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
MC74VHC1GU04DFT1 is packaged in SC-88A (Case 419A), a 5-pin surface-mount package with 0.65 mm pitch and 2.1 mm × 1.25 mm footprint. Pin 1 is marked with a dot or beveled corner per JEDEC MO-178.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected - must remain floating or grounded per layout best practice; no electrical function |
| 2 | Input (A) | Inverting logic input - accepts TTL- or CMOS-compatible signals; overvoltage tolerant to 5.5 V |
| 3 | GND | Ground reference - return path for all internal currents; requires low-inductance PCB connection |
| 4 | Output (Y) | Inverted logic output - drives complementary signal with rail-to-rail swing and 8 mA sink/source capability |
| 5 | VCC | Positive supply - powers internal circuitry; bypass capacitor (100 nF) recommended within 2 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered architecture | Eliminates internal staging to reduce propagation delay by ~30% vs buffered inverters and preserve signal edge fidelity |

FAQ
What is the maximum input voltage rating for MC74VHC1GU04DFT1?
The MC74VHC1GU04DFT1 supports DC input voltages up to 5.5 V regardless of VCC level, enabling safe interfacing with 5 V logic even when powered from 2.0–3.3 V supplies. This overvoltage tolerance is implemented via internal protection diodes and does not require external components. Exceeding 5.5 V may damage the input structure.
Does MC74VHC1GU04DFT1 support partial power-down operation?
Yes, MC74VHC1GU04DFT1 features IOFF circuitry that limits input leakage current to ≤10 µA when VCC = 0 V and VIN = 5.5 V. This allows the device to be safely inserted into a live backplane or used in multi-rail systems where some supplies are inactive, preventing unintended current paths and signal corruption on shared buses.
What is the typical propagation delay of MC74VHC1GU04DFT1 at 3.3 V?
At VCC = 3.3 V and CL = 15 pF, the MC74VHC1GU04DFT1 exhibits a typical propagation delay (tPLH/tPHL) of 3.5 ns, with a maximum of 12.0 ns over the full −55 °C to +125 °C operating range. This performance is confirmed in the AC Electrical Characteristics table on page 4 of the official datasheet.
Which package type does MC74VHC1GU04DFT1 use?
MC74VHC1GU04DFT1 uses the SC-88A package (JEDEC MO-178, Case 419A), a 5-pin surface-mount outline measuring 2.1 mm × 1.25 mm with 0.65 mm lead pitch. It is identical in footprint to SC-70-5 and SOT-353, and pin 1 is marked with a dot or bevel per standard marking conventions.
Can MC74VHC1GU04DFT1 be used in crystal oscillator circuits?
Yes, MC74VHC1GU04DFT1 is commonly deployed as the gain element in Pierce crystal oscillator configurations due to its unbuffered architecture, low input capacitance (4.0 pF), and ability to operate linearly with appropriate feedback biasing. Its 2.5 ns propagation delay at 5 V supports stable oscillation up to 20 MHz with standard AT-cut crystals.
