onsemi MC74VHC1GU04DFT2G

Overview

MC74VHC1GU04DFT2G from onsemi is a single unbuffered CMOS inverter optimized for high-speed logic inversion in space-constrained applications, featuring 2.5 ns propagation delay at 5 V, 2.0–5.5 V supply operation, and 5.5 V input overvoltage tolerance. It serves as a level-shifting buffer between 3 V and 5 V domains in portable instrumentation, sensor interface circuits, and clock signal conditioning.

For engineers reviewing the MC74VHC1GU04DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include unbuffered inverter topology, SC-88A package footprint, IOFF partial power-down support, and guaranteed operation across −55 °C to +125 °C industrial temperature range.

Technical Context

The MC74VHC1GU04DFT2G implements a single-stage CMOS inverter without internal buffering, delivering fast edge response with minimal propagation delay variation across voltage and temperature. Its input structure incorporates overvoltage-tolerant protection diodes enabling safe interfacing of 5 V signals into 3 V systems without external clamping.

IOFF circuitry disables input leakage during power-down states, preventing back-driving of powered rails in partial-power-down architectures. The device operates with rail-to-rail output swing and supports 8 mA drive strength at 3.0 V, meeting requirements for driving light capacitive loads in mixed-voltage digital subsystems.

FAQ

What is the maximum input voltage rating for MC74VHC1GU04DFT2G?

The MC74VHC1GU04DFT2G supports DC input voltages up to 5.5 V regardless of VCC level, enabling safe interfacing of 5 V signals into 3 V systems without external protection components. This overvoltage tolerance is achieved through integrated input clamp diodes and is specified across the full operating temperature range of −55 °C to +125 °C.

Does MC74VHC1GU04DFT2G support partial power-down operation?

Yes, MC74VHC1GU04DFT2G features IOFF circuitry that actively disables input leakage current when VCC = 0 V, preventing back-driving of powered rails. Measured IOFF is ≤10 µA at VIN = 5.5 V and TA = 25 °C, making MC74VHC1GU04DFT2G suitable for hot-swap and multi-rail power sequencing applications.

What package type is used for MC74VHC1GU04DFT2G?

MC74VHC1GU04DFT2G is supplied in the SC-88A (also known as SOT-353 or MO-178) package: a 5-pin, 2.0 × 1.25 mm surface-mount outline with 0.65 mm lead pitch. Pin 1 is identified by a dot or beveled corner, and the package is Pb-free, halogen-free, and RoHS compliant per onsemi's standard qualification.

Can MC74VHC1GU04DFT2G be used in oscillator circuits?

Yes, MC74VHC1GU04DFT2G is explicitly recommended for oscillator applications due to its unbuffered inverter topology, low input capacitance (4.0 pF), and predictable propagation delay. When combined with external resistors and capacitors in a Pierce configuration, MC74VHC1GU04DFT2G delivers stable, low-jitter clock generation suitable for sensor sampling and serial communication timing.

What is the typical propagation delay of MC74VHC1GU04DFT2G at 3.3 V?

At VCC = 3.3 V and CL = 15 pF, the typical propagation delay (tPLH/tPHL) of MC74VHC1GU04DFT2G is 3.5 ns, with a maximum of 10.5 ns over the full industrial temperature range (−40 °C to +85 °C). This value is confirmed in the AC Electrical Characteristics table of the official onsemi datasheet (Rev. 25, Jan 2026).
