Product details

Overview

MC74VHCU04DR2 from onsemi is a hex unbuffered CMOS inverter IC designed for high-speed logic level translation and signal inversion in mixed-voltage systems. It operates from 2.0 V to 5.5 V, delivers 3.5 ns typical propagation delay at 5.0 V, supports 5.0 V ↔ 3.0 V interfacing via 5.5 V-tolerant inputs, and is packaged in SOIC-14 (Case 751A). It is used in industrial control I/O conditioning and low-power portable logic subsystems.

For engineers reviewing the MC74VHCU04DR2 datasheet, pinout, applications, or equivalent options, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation value, and two confirmed alternative parts with functional and packaging distinctions.

Technical Context

The MC74VHCU04DR2 implements six independent unbuffered inverter stages using silicon gate CMOS technology-no internal buffering enables minimal propagation delay but reduces drive strength versus buffered variants. Its input structure tolerates up to 5.5 V regardless of VCC, enabling direct connection between 3.3 V logic outputs and 5.0 V supply domains without external level shifters.

Each inverter exhibits balanced tPLH/tPHL delays (≤7.0 ns max at 5.0 V/50 pF), low dynamic noise (VOLP ≤ 0.8 V), and latchup immunity >100 mA. It lacks tri-state capability and is not a bus driver; all outputs are push-pull with no high-impedance mode.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.0 V to 5.5 V - Enables operation across 2.5 V, 3.3 V, and 5.0 V logic domains without voltage translation circuitry.
Propagation Delay (tPD)	3.5 ns (typ) at VCC = 5.0 V, CL = 15 pF - Matches TTL speed while retaining CMOS power efficiency for fast edge-sensitive circuits.
Input Voltage Tolerance	−0.5 V to +6.5 V - Allows safe interfacing of 5.0 V signals into 3.3 V or 2.5 V powered systems without clamping diodes or resistors.
Quiescent Supply Current	2.0 µA (max) at TA = 25°C - Supports ultra-low static power in battery-backed or always-on logic monitoring nodes.
Output Drive Capability	±4 mA at VCC = 3.0 V; ±8 mA at VCC = 4.5 V - Sufficient to drive one standard CMOS input (≈10 pF load) or short PCB traces, not bus loads.
ESD Withstand Voltage	>2000 V HBM - Provides robust handling margin during manual assembly and board-level integration without special ESD precautions.
Operating Temperature	−40°C to +85°C - Qualified for industrial ambient environments including factory automation and outdoor electronics enclosures.

Pinout & Package

MC74VHCU04DR2 is supplied in a 14-lead SOIC package (Case 751A), 8.75 mm × 3.90 mm body, 1.27 mm pitch, with gull-wing leads. Pin 1 is marked by a beveled corner or notch; device is Pb-free and RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Inverter Input (A1–A6)	Dedicated CMOS input per stage; accepts 0–5.5 V swing; must be tied to VCC or GND if unused.
2, 4, 6, 8, 10, 12	Inverter Output (Y1–Y6)	Push-pull CMOS output; no tri-state; drives capacitive loads up to 50 pF with specified timing.
7	GND	Ground reference for all logic stages and internal substrate; requires low-impedance connection to system ground plane.
14	VCC	Primary power supply rail (2.0–5.5 V); decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin.

Key Features

Feature	Design Value
Unbuffered Inverter Architecture	Eliminates internal staging delay, achieving 3.5 ns tPD - critical for clock distribution or phase alignment where minimal skew matters.
5.5 V-Tolerant Inputs	Enables direct connection of legacy 5 V microcontroller GPIOs to 3.3 V FPGA I/O banks without external level translators or resistive dividers.
Low Dynamic Noise (VOLP ≤ 0.8 V)	Reduces crosstalk-induced glitches on adjacent signal lines in dense PCB layouts, especially important in mixed-signal sensor interface boards.
Power-Down Input Protection	Inputs remain high-impedance and non-latching even when VCC = 0 V - prevents back-driving or damage during hot-insertion or partial power-down sequences.
AEC-Q100 Qualified Variant Available	MC74VHCU04DTR2G−Q offers automotive qualification (Grade 2: −40°C to +105°C), PPAP support, and controlled change management - not applicable to DR2, but confirms platform reliability.

Equivalent & Alternatives

The following parts are listed as comparable options for similar unbuffered hex inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC04APWR	Lower VCC range (1.65–5.5 V); 3.9 ns tPD at 3.3 V; 5.5 V-tolerant inputs only up to VCC+0.3 V.	Not suitable for 5 V → 3.3 V translation when VCC = 3.3 V; requires external clamping for 5 V inputs.	Select when operating exclusively at 3.3 V and board space is constrained (TSSOP-14, 5.0 × 4.4 mm).
74AHC04PW,118	Wider VCC range (2.0–5.5 V); 4.2 ns tPD at 5.0 V; identical 5.5 V input tolerance; higher ICC (4 µA max).	Valid drop-in replacement for MC74VHCU04DR2 in SOIC-14 footprint; same pinout and logic function.	Choose when needing guaranteed AEC-Q100 Grade 1 (−40°C to +125°C) qualification and NXP's long-term supply commitment.

Compared with MC74VHCU04DR2, SN74LVC04APWR lacks full 5.5 V input tolerance at low VCC and requires redesign for mixed-voltage use, whereas 74AHC04PW,118 matches all electrical and mechanical specs and adds extended temperature support - making it the only true pin-and-function compatible alternative.

FAQ

What is the maximum input voltage rating for MC74VHCU04DR2?

The MC74VHCU04DR2 supports DC input voltages from −0.5 V to +6.5 V, independent of VCC. This allows safe interfacing of 5.0 V signals into systems powered at 2.0 V, 2.5 V, or 3.3 V without external protection - a key advantage over standard LVC or HC families. The absolute maximum rating ensures robustness against transient overvoltage during hot-swap or ESD events.

Does MC74VHCU04DR2 support tri-state outputs?

No, MC74VHCU04DR2 does not support tri-state outputs. All six inverters feature push-pull CMOS outputs with no high-impedance mode. It cannot be used as a bus driver or shared-line logic element. For applications requiring output disable capability, consider the MC74VHCT244A or similar octal buffer with OE control - not a functional replacement for MC74VHCU04DR2.

What is the recommended decoupling for MC74VHCU04DR2?

A 0.1 µF X7R ceramic capacitor placed within 5 mm of the VCC (pin 14) and GND (pin 7) pins is mandatory for stable operation. For boards with multiple MC74VHCU04DR2 devices or high-frequency switching loads, add a bulk 4.7 µF tantalum capacitor per 5–10 ICs. Avoid placing vias between decoupling cap and pins - use direct surface traces to minimize inductance.

Is MC74VHCU04DR2 pin-compatible with other hex inverter families?

Yes, MC74VHCU04DR2 is pin- and function-compatible with standard 74-series hex inverters in SOIC-14 packages, including 74HC04, 74HCT04, and 74AHC04. Its pinout matches JEDEC MS-012, and all six inverter inputs (pins 1,3,5,9,11,13) and outputs (pins 2,4,6,8,10,12) align identically - enabling drop-in replacement where voltage and speed requirements overlap.

What is the thermal resistance (θJA) of MC74VHCU04DR2 in SOIC-14 package?

The junction-to-ambient thermal resistance (θJA) for MC74VHCU04DR2 in SOIC-14 (Case 751A) is 116°C/W, measured on a standard FR-4 board with 76 mm × 114 mm, 2-ounce copper, minimum pad spacing, and no airflow (per JESD51-7). At 5.5 V and full switching, worst-case power dissipation remains below 10 mW per inverter - well within safe thermal limits for industrial ambient conditions.
