Product details
Overview
MC74VHC1GU04MU1TCG from onsemi is a single unbuffered CMOS inverter in UDFN6 (1.45 × 1.0 mm) package, operating from 2.0 V to 5.5 V supply, with 2.5 ns typical propagation delay at 5 V, ±8 mA output drive at 3.0 V, and input over-voltage tolerance up to 5.5 V-enabling 3 V/5 V mixed-signal level translation in space-constrained logic interfaces.
For engineers reviewing the MC74VHC1GU04MU1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include unbuffered inverter topology for oscillator/pulse-shaping use, IOFF-enabled partial power-down capability, SC-88A/SC-74A/UDFN6 package compatibility, and guaranteed operation across −55 °C to +125 °C industrial temperature range.
Technical Context
The MC74VHC1GU04MU1TCG implements a single-stage unbuffered inverter gate with high-input impedance and rail-to-rail output swing, optimized for low-capacitance signal inversion without internal buffering stages-making it suitable for crystal oscillator feedback paths and Schmitt-triggerless waveform shaping. Its IOFF feature disables input leakage during power-down, preventing back-driving of powered rails.
Input voltage tolerance extends to 5.5 V independent of VCC, allowing safe interfacing between 5 V legacy peripherals and 3 V microcontrollers. Propagation delay is specified down to 2.5 ns (typ) at 5 V with 15 pF load, and input capacitance is tightly controlled at 4.0 pF (typ), minimizing loading on driving sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports dual-supply systems and battery-powered 3 V designs with 5 V tolerant inputs |
| tPD (Typ) | 2.5 ns at VCC = 5 V, CL = 15 pF - enables high-speed clock inversion or pulse edge sharpening in timing-critical paths |
| IOH/IOL | ±8 mA at VCC = 3.0 V - sufficient to drive multiple 74LVC inputs or small LED indicators without external buffers |
| VIN Tolerance | Up to 5.5 V regardless of VCC - eliminates need for external level-shifters when interfacing 5 V sensors to 3 V logic |
| IOFF Support | Active during power-down - prevents current flow into powered subsystems when VCC = 0 V, critical for hot-swap and partial-power-down systems |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive, industrial control, and outdoor embedded applications |
| Package | UDFN6 (1.45 × 1.0 mm, 0.5 mm pitch) - ultra-compact footprint ideal for wearables, sensor nodes, and miniaturized PCBs |
Pinout & Package
MC74VHC1GU04MU1TCG is housed in a 6-pin UDFN (1.45 × 1.0 mm, 0.5 mm pitch) package with wettable flanks and exposed thermal pad. Pin 1 is marked by a corner chamfer per JEDEC MO-229, and the package is RoHS-compliant, Pb-free, and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must be left floating or tied to GND for mechanical stability-no electrical function |
| 2 | Input (A) | Inverting logic input; accepts 0–5.5 V signals regardless of VCC; high-impedance CMOS node |
| 3 | GND | Digital ground reference; must be low-inductance connection to system ground plane |
| 4 | Output (Y) | Inverted logic output; rail-to-rail swing (0 V to VCC); capable of sourcing/sinking ±8 mA at 3 V |
| 5 | No Connect (NC) | Internally unconnected; no routing required; may be used as thermal pad anchor point |
| 6 | VCC | Positive supply input; decoupling capacitor (0.1 µF ceramic) required within 2 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered Inverter Topology | Single CMOS stage with no internal buffering-enables precise phase control in Pierce oscillators and minimal delay in pulse reshaping |
| Input Over-Voltage Tolerance | 5.5 V absolute max input voltage independent of VCC-allows direct interface to 5 V I²C, UART, or GPIO without external resistors |
| IOFF Partial Power-Down | Input leakage < 10 µA when VCC = 0 V-prevents back-powering of upstream logic during sleep modes |
| Low Input Capacitance | 4.0 pF typical-reduces loading on high-impedance sources such as crystal resonators or analog comparators |
| Wide Temperature Range | −55 °C to +125 °C operation-validated for automotive engine control units and industrial motor drives |

FAQ
What is the maximum input voltage rating for MC74VHC1GU04MU1TCG?
The MC74VHC1GU04MU1TCG supports DC input voltages up to 5.5 V regardless of VCC level, enabling safe interfacing with 5 V peripherals even when operating from a 2.0–3.3 V supply. This over-voltage tolerance is explicitly guaranteed in the Absolute Maximum Ratings table and does not require external clamping diodes or resistive dividers.
Does MC74VHC1GU04MU1TCG support partial power-down operation?
Yes, the MC74VHC1GU04MU1TCG features IOFF circuitry that actively disables input leakage current when VCC = 0 V. Per the datasheet's DC Electrical Characteristics, IOFF is limited to 10 µA maximum at VIN = 5.5 V and VCC = 0 V-ensuring no back-current flows into powered subsystems during sleep or hot-swap events.
What is the propagation delay of MC74VHC1GU04MU1TCG at 3.3 V supply?
At VCC = 3.3 V and CL = 15 pF, the MC74VHC1GU04MU1TCG exhibits a typical propagation delay (tPLH/tPHL) of 3.5 ns, with a maximum of 10.5 ns over the full −40 °C to +85 °C temperature range. These values are confirmed in the AC Electrical Characteristics table on page 4 of the official datasheet.
Can MC74VHC1GU04MU1TCG be used in crystal oscillator circuits?
Yes-the unbuffered inverter architecture of MC74VHC1GU04MU1TCG is explicitly recommended in the datasheet for oscillator and pulse-shaping applications. Its single-stage design provides the precise phase inversion and gain needed in Pierce oscillator configurations, especially when paired with 32.768 kHz tuning-fork crystals in real-time clock circuits.
What is the thermal resistance (θJA) of MC74VHC1GU04MU1TCG in its UDFN6 package?
The MC74VHC1GU04MU1TCG in UDFN6 package has a junction-to-ambient thermal resistance (θJA) of 154 °C/W, measured per JESD51-7 on an FR4 board with minimum pad spacing and no airflow. This value is documented in the Maximum Ratings table on page 3 and supports continuous operation up to 125 °C ambient when power dissipation remains below 812 mW.
