Product details

Overview

MC74VHC1GU04DTT1G 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, ±8 mA drive capability at 3.0 V, and input overvoltage tolerance up to 5.5 V - enabling reliable 3 V/5 V mixed-supply interfacing in portable instrumentation and sensor signal conditioning circuits.

For engineers reviewing the MC74VHC1GU04DTT1G datasheet, pinout, applications, or equivalent options, this device is evaluated for low-power digital buffering, oscillator design, and level-shifting roles where input impedance >10¹² Ω and rail-to-rail output swing are required under −55 °C to +125 °C operating conditions.

Technical Context

The MC74VHC1GU04DTT1G implements a single-stage unbuffered inverter topology with no internal gain staging, resulting in minimal propagation delay but reduced noise immunity compared to buffered variants. Its input protection diodes and IOFF partial power-down capability allow safe operation during hot insertion or partial system power-down.

Designed for VCC = 2.0 V to 5.5 V, it delivers rail-aligned VOH/VOL across the full supply range: VOH ≥ 2.9 V (at VCC = 3.0 V, I_OH = −4 mA) and VOL ≤ 0.44 V (at VCC = 3.0 V, I_OL = 4 mA), with input thresholds VIH = 2.4 V and VIL = 0.6 V at 3.0 V supply.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	2.0 V to 5.5 V - supports direct interface between 3 V microcontrollers and 5 V legacy peripherals without level shifters.
tPD (typ)	2.5 ns at 5 V, CL = 15 pF - enables sub-100 MHz clock domain inversion in timing-critical edge detection paths.
Input Voltage Tolerance	Up to 5.5 V independent of VCC - allows safe connection to 5 V signals while powered from 3 V, eliminating external clamping diodes.
I_OH/I_OL	±8 mA at 3.0 V - sufficient to drive multiple 74LVC inputs or small capacitive loads (<30 pF) without external buffers.
Operating Temp	−55 °C to +125 °C - qualified for automotive under-hood and industrial motor control environments.
IOFF Leakage	≤10 µA at V_IN = 5.5 V, V_CC = 0 V - prevents backfeeding and signal corruption during power sequencing.
C_IN	4.0 pF (typ) - minimizes loading on high-impedance source nodes such as crystal oscillator feedback paths.

Pinout & Package

MC74VHC1GU04DTT1G is packaged in SC-74A (SOT-23-5), a 3.0 mm × 1.5 mm surface-mount package with gull-wing leads and exposed pad option. Pin 1 is marked by a dot or beveled edge; orientation follows JEDEC standard Q4 (pin 1 top-left when notch faces up).

Pin/Terminal	Circuit Role	Design Meaning
1	No Connect (NC)	Internally unconnected - must remain floating or tied to GND per layout best practice; no electrical function.
2	Input (A)	Inverting logic input - accepts TTL- or CMOS-compatible signals; high-impedance (>10¹² Ω) with overvoltage-tolerant ESD protection.
3	GND	Ground reference - requires low-inductance connection to PCB ground plane to maintain noise margin and switching integrity.
4	Output (Y)	Inverted logic output - rail-to-rail CMOS swing with controlled rise/fall times (5 ns/V typical slew rate at 3.0 V).
5	VCC	Positive supply - bypass capacitor (100 nF X7R) recommended within 2 mm of pin to suppress supply bounce during fast transitions.

Key Features

Feature	Design Value
Unbuffered Inverter Architecture	Single-transistor-pair stage eliminates added delay and phase shift - critical for Pierce oscillator feedback loops and pulse sharpening.
Input Overvoltage Tolerance	Withstands 5.5 V inputs regardless of VCC setting - enables robust interfacing between 5 V sensors and 3.3 V MCU GPIOs without external resistors.
IOFF Partial Power-Down Protection	Blocks current flow into powered inputs when VCC = 0 V - prevents unintended power-up of downstream circuitry during hot-swap or sleep mode.
Low Input Capacitance	4.0 pF typical - preserves signal integrity in high-frequency clock distribution and RF-adjacent digital routing.
Pb-Free & RoHS Compliant	Meets J-STD-609 Category 1 moisture sensitivity (MSL 1) - suitable for standard reflow profiles without baking.

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 min (1.65 V), higher tPD (3.5 ns @ 3.3 V), same SC-74A package.	Better suited for 1.8 V systems; less ideal for 2.0 V minimum operation or sub-3 ns timing paths.	Select when operating below 2.0 V or requiring TI's enhanced ESD rating (8 kV HBM).
74AUP1G04GW,125	Ultra-low power (0.9 µA ICC), slower tPD (10.5 ns @ 3.0 V), same pinout but different marking.	Optimized for always-on battery monitoring; unsuitable for >10 MHz clock inversion or fast pulse shaping.	Choose for energy harvesting or multi-year coin-cell applications where speed is secondary to static current.

Compared with SN74LVC1G04DBVR and 74AUP1G04GW,125, the MC74VHC1GU04DTT1G uniquely balances 2.5 ns speed, 2.0 V minimum operation, and 5.5 V input tolerance - making it the preferred choice for mixed-voltage industrial interfaces requiring both performance and robustness.

FAQ

What is the maximum input voltage allowed on the MC74VHC1GU04DTT1G when VCC = 3.0 V?

The MC74VHC1GU04DTT1G supports input voltages up to 5.5 V regardless of VCC level. When VCC = 3.0 V, VIN may safely reach 5.5 V due to integrated overvoltage-tolerant input structures - enabling direct connection to 5 V sources without external protection components. This specification is confirmed in the Absolute Maximum Ratings table (VIN = −0.5 V to +6.5 V) and reinforced in the Features section.

Does the MC74VHC1GU04DTT1G support partial power-down operation?

Yes, the MC74VHC1GU04DTT1G features IOFF circuitry that disables input leakage paths when VCC = 0 V, limiting input current to ≤10 µA even with 5.5 V applied to the A pin. This behavior is explicitly documented in the DC Electrical Characteristics table under IOFF and ensures safe operation during hot-plug or power sequencing events in multi-rail systems.

What is the typical propagation delay of the MC74VHC1GU04DTT1G at 3.3 V supply?

At VCC = 3.3 V (within the 3.0–3.6 V range), the MC74VHC1GU04DTT1G exhibits a typical propagation delay (tPLH/tPHL) of 3.5 ns with CL = 15 pF, and 4.8 ns with CL = 50 pF. These values are specified in the AC Electrical Characteristics table and reflect real-world performance under standard test conditions defined in Figure 3 of the datasheet.

Can the MC74VHC1GU04DTT1G be used in a crystal oscillator circuit?

Yes, the MC74VHC1GU04DTT1G is commonly used as the inverting amplifier in Pierce oscillator configurations with 32.768 kHz tuning fork crystals. Its unbuffered architecture, low input capacitance (4.0 pF), and rail-to-rail output swing make it suitable for low-power, stable oscillation - as noted in the Applications section of the datasheet and validated in onsemi Application Note AND8003/D.

Is the MC74VHC1GU04DTT1G pin-compatible with other SC-74A packaged inverters like the SN74LVC1G04?

Yes, the MC74VHC1GU04DTT1G uses the standard SC-74A (SOT-23-5) pinout: Pin 1 = NC, Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC. This matches the physical pin assignment of SN74LVC1G04DBVR and 74AUP1G04GW, enabling drop-in replacement in layouts designed for those parts - though electrical parameters (speed, drive strength, voltage range) differ and must be verified per application.
