Product details

Overview

MC74VHC04DR2 from onsemi is a high-speed CMOS hex inverter IC designed for logic-level inversion in 2 V to 5.5 V digital systems. It features 3.8 ns typical propagation delay at 5 V, 2 µA max quiescent current at 25 °C, full 5.0 V CMOS output swing, and TTL-compatible input tolerance up to 5.5 V - enabling robust 3.3 V/5 V level translation in microcontroller I/O buffering and clock signal conditioning.

For engineers reviewing the MC74VHC04DR2 datasheet, pinout, applications, or equivalent options, this device serves as a low-power, noise-immune inverter for bus driving, waveform shaping, and oscillator circuits where balanced tPLH/tPHL and 28% VCC noise margin are critical.

Technical Context

The MC74VHC04DR2 implements six independent CMOS inverter stages using silicon gate technology, each with a three-stage internal buffer architecture that enhances noise immunity and stabilizes output transitions. Its input structures tolerate voltages up to 5.5 V regardless of VCC, supporting mixed-voltage interfacing without external clamping.

It operates across −55 °C to +125 °C with rail-to-rail CMOS output swing (0 V to VCC), and its ESD rating exceeds 2000 V HBM. The device is not tri-state; all outputs are push-pull, and unused inputs must be tied to VCC or GND per specification.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.0 V to 5.5 V - supports direct integration into 3.3 V and 5 V logic domains without level shifters.
Propagation Delay (tPD)	3.8 ns (typ) at VCC = 5 V, CL = 15 pF - enables reliable operation in >100 MHz clock distribution paths.
Quiescent ICC	2 µA (max) at TA = 25 °C - ensures ultra-low static power in battery-backed or always-on control logic.
Noise Immunity	VNIH = VNIL = 28% VCC - provides strong rejection of coupled transients in noisy industrial environments.
Input Voltage Tolerance	−0.5 V to +6.5 V - allows safe interfacing between 5 V peripherals and 3.3 V hosts without damage risk.
Output Drive	±8 mA at VCC = 4.5 V - sufficient to drive 15 pF loads with <8.5 ns max delay over full temperature range.
ESD Rating	HBM > 2000 V - meets industrial handling requirements without additional protection circuitry.

Pinout & Package

MC74VHC04DR2 is supplied in a 14-lead SOIC package (Case 751A), 8.75 mm × 4.00 mm footprint, with standard 1.27 mm pitch. Pin 1 is marked by a notch or dot; the device has no exposed pad or thermal tab.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Inverter Input (A1–A6)	CMOS-compatible inputs accepting 0–5.5 V; require explicit tie-high or tie-low if unused.
2, 4, 6, 8, 10, 12	Inverter Output (Y1–Y6)	Push-pull CMOS outputs delivering rail-to-rail swing (0 V to VCC); not tri-state capable.
7	GND	Ground reference for all logic and power domains; must be low-impedance connection.
14	VCC	Primary supply rail (2.0–5.5 V); bypassing with 0.1 µF ceramic capacitor near pin is mandatory.

Key Features

Feature	Design Value
High-Speed Operation	3.8 ns typical propagation delay at 5 V enables use in fast timing-critical paths such as clock buffers and pulse shaping.
Low-Power CMOS Architecture	2 µA max ICC at 25 °C reduces system standby power and thermal load in dense PCB layouts.
Wide-Voltage Input Tolerance	Inputs withstand −0.5 V to +6.5 V, permitting safe 5 V signal injection into 3.3 V systems without external protection.
High Noise Immunity	28% VCC noise margin ensures stable operation in electrically noisy environments like motor drives and PLC I/O modules.
Pb-Free & RoHS Compliant	Meets global environmental regulations; compatible with lead-free reflow profiles (JEDEC J-STD-020).

Equivalent & Alternatives

The following parts are listed as comparable options for similar 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 V tolerant inputs only up to 5.5 V with Ioff protection.	Better suited for 1.8 V/3.3 V systems; lacks guaranteed 2 V operation and higher noise margin (20% vs 28% VCC).	Select when operating below 2.0 V or requiring Ioff during partial power-down.
74HC04D,653	Slower (19 ns tPD at 4.5 V); higher ICC (4 µA max); identical 2–6 V VCC range and pinout.	Acceptable for non-timing-critical logic but unsuitable for >25 MHz clock paths or ultra-low-power designs.	Choose for cost-sensitive legacy designs where speed and quiescent current are not limiting.

Compared with SN74LVC04APWR and 74HC04D,653, the MC74VHC04DR2 delivers superior propagation delay at 2–5.5 V operation, tighter noise margin, and lower ICC - making it optimal for mixed-voltage industrial control and timing-critical embedded interfaces.

FAQ

What is the maximum operating temperature for the MC74VHC04DR2?

The MC74VHC04DR2 is rated for operation from −55 °C to +125 °C per its Recommended Operating Conditions table. This extended range is validated across all electrical parameters including propagation delay, output drive, and noise immunity - making MC74VHC04DR2 suitable for under-hood automotive modules and industrial motor controllers where ambient temperatures exceed 85 °C.

Does the MC74VHC04DR2 support 3.3 V to 5 V level translation?

Yes, the MC74VHC04DR2 supports bidirectional level translation between 3.3 V and 5 V domains. Its inputs tolerate up to 5.5 V regardless of VCC, and its outputs deliver full 5.0 V CMOS swings when powered at 5 V - enabling clean signal inversion from a 3.3 V microcontroller to a 5 V peripheral without external components. MC74VHC04DR2 achieves this while maintaining 3.8 ns typical delay and 28% VCC noise margin.

Is the MC74VHC04DR2 pin-compatible with standard 74-series hex inverters?

Yes, the MC74VHC04DR2 uses the industry-standard 14-pin SOIC layout with identical pinout to 74HC04, 74LS04, and 74LVC04 devices. Pin 1 is input A1, Pin 2 is output Y1, continuing through Pin 13 (A6) and Pin 12 (Y6), with VCC on Pin 14 and GND on Pin 7. This allows drop-in replacement in existing designs, though voltage and timing behavior must be verified per application.

What is the input capacitance of the MC74VHC04DR2?

The MC74VHC04DR2 has a maximum input capacitance (Cin) of 10 pF, specified across temperature and voltage conditions. This low value minimizes loading on upstream drivers and preserves signal edge rates in high-frequency applications such as clock distribution and oscillator feedback loops - a key advantage over older 74HC-family parts with higher Cin.

Can unused inputs on the MC74VHC04DR2 be left floating?

No, unused inputs on the MC74VHC04DR2 must never be left floating. Per the datasheet's Recommended Operating Conditions note, all unused inputs must be tied to a valid logic level - either VCC or GND - to prevent increased ICC, erratic switching, or potential latch-up. Floating inputs cause undefined internal node voltages and can degrade noise immunity and power efficiency of the entire MC74VHC04DR2 device.
