Product details
Overview
MC74VHC04DT from ON Semiconductor is a hex inverter IC designed for high-speed logic level translation and signal conditioning in mixed-voltage digital systems. It features six independent inverters, operates from 2.0 V to 5.5 V, delivers 3.8 ns typical propagation delay at 5 V, supports 5 V ↔ 3 V interfacing via 7 V-tolerant inputs, and is housed in a 14-lead TSSOP package.
For engineers reviewing the MC74VHC04DT datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage flexibility (2–5.5 V), input overvoltage tolerance (up to 7 V), low quiescent current (≤2 μA), balanced propagation delays, and compatibility with standard logic families including TTL and CMOS.
Technical Context
The MC74VHC04DT implements six independent CMOS inverter stages using silicon gate technology, each with a three-stage internal buffer structure that enhances noise immunity and output stability. Its inputs tolerate up to 7 V regardless of VCC, enabling robust 5 V-to-3 V system interfacing without external level shifters.
It exhibits balanced tPLH/tPHL propagation delays, low dynamic noise (VOLP ≤ 0.8 V), and latch-up immunity exceeding 300 mA. The device meets HBM ESD > 2000 V and is specified across −40 °C to +85 °C operating temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - Enables operation across 3.3 V and 5 V systems without level-shifting circuitry. |
| Typical Propagation Delay | 3.8 ns at VCC = 5 V, CL = 15 pF - Matches Bipolar Schottky TTL speed while retaining CMOS power efficiency. |
| Input Voltage Tolerance | −0.5 V to +7.0 V - Allows safe connection of 5 V outputs to 3 V-powered MC74VHC04DT inputs. |
| Quiescent Supply Current | ≤2 μA at TA = 25 °C - Supports ultra-low-power standby modes in battery-operated or energy-sensitive designs. |
| Noise Immunity | VNIH = VNIL = 28% VCC - Ensures reliable switching in electrically noisy industrial or automotive environments. |
| Output Drive Capability | ±8 mA at VCC = 4.5 V - Sufficient to drive multiple standard CMOS/TTL loads or short PCB traces directly. |
| ESD Rating (HBM) | >2000 V - Meets IEC 61000-4-2 Level 2 requirements for handling and board-level robustness. |
Pinout & Package
MC74VHC04DT is packaged in a 14-lead Thin Shrink Small Outline Package (TSSOP), case 948G−01, with 0.65 mm lead pitch and JEDEC-standard footprint. The package is Pb-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Inverter Inputs (A1–A6) | CMOS-compatible inputs tolerant to 7 V; accept logic-high thresholds as low as 0.3×VCC. |
| 2, 4, 6, 8, 10, 12 | Inverter Outputs (Y1–Y6) | Pull-up/pull-down complementary outputs capable of sourcing/sinking ±8 mA at 4.5 V. |
| 7 | GND | Ground reference for all logic and power domains; must be low-impedance for noise control. |
| 14 | VCC | Primary power supply (2.0–5.5 V); decoupling capacitor required within 1 cm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed CMOS Architecture | 3.8 ns typical tPD at 5 V enables use in 100+ MHz clock distribution and data path inversion. |
| 7 V-Tolerant Inputs | Eliminates need for external clamping diodes or level translators when interfacing 5 V controllers to 3 V logic subsystems. |
| Power-Down Input Protection | Inputs remain high-impedance and non-latching during VCC = 0 V, preventing back-driving or damage in partial-power-down states. |
| Latch-Up Immunity | Exceeds 300 mA per JEDEC JESD78 - ensures reliability in transient-overstress conditions common in industrial control. |
| Pb-Free & RoHS-Compliant | Meets global environmental regulations; compatible with lead-free reflow soldering profiles (peak 260 °C). |
Applications
| Industrial PLC I/O Conditioning | Automotive Body Control Module Logic |
|---|---|
Use Scenario: Inverting sensor status signals (e.g., door open/closed, switch position) before feeding into microcontroller GPIOs with limited interrupt-capable pins. IC Role / Device Role / Timing Role: Signal polarity correction and noise-filtered buffering; no timing-critical path, but requires stable DC logic levels under EMI. Use Value: 7 V-tolerant inputs accept direct connection to 5 V pull-up sensors; low ICC (<2 μA) extends battery life in always-on monitoring circuits. |
Use Scenario: Driving discrete LED indicators and relay drivers from 3.3 V MCU outputs while maintaining compatibility with legacy 5 V automotive bus signaling standards. IC Role / Device Role / Timing Role: Voltage-level translation and fanout expansion; used in non-timing-critical combinatorial logic paths. Use Value: Balanced tPLH/tPHL ensures predictable setup/hold margins; ±8 mA drive supports direct LED biasing without external transistors. |
| Consumer Audio Device Power Sequencing | Medical Diagnostic Instrument Data Path |
Use Scenario: Generating inverted enable signals for sequenced power rails (e.g., analog front-end before digital core) in portable ultrasound or hearing aid processors. IC Role / Device Role / Timing Role: Glue logic for deterministic power-up/down sequencing; operates in sub-100 ns window between rail stabilization events. Use Value: 2.0–5.5 V range allows single part to manage both 3.3 V and 1.8 V domain sequencing; low VOLP (≤0.8 V) prevents false triggering during rail transitions. |
Use Scenario: Inverting serial data lines (e.g., RS-232 level-shifted signals) and control strobes in portable ECG or pulse oximeter modules where space and BOM count are constrained. IC Role / Device Role / Timing Role: Signal inversion and load isolation in low-noise analog-digital boundary zones; not on critical ADC sampling path. Use Value: High noise immunity (28% VCC) suppresses coupling from adjacent high-speed clocks; TSSOP package enables dense routing near sensitive analog sections. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC04APW | Lower VCC range (1.65–5.5 V); 3.9 ns tPD at 3.3 V; 5 V-tolerant inputs only (not 7 V). | Best suited for pure 3.3 V systems with tight board space; lacks MC74VHC04DT's 5 V ↔ 3 V bridging capability. | Select when operating exclusively at 3.3 V and requiring AEC-Q100 qualification (available in automotive grade). |
| 74AHC04PW | Wider VCC range (2–5.5 V); identical 7 V input tolerance; 4.0 ns tPD at 5 V; higher ICC (max 4 μA vs. 2 μA). | Functionally interchangeable in most designs; slightly higher static power may impact battery lifetime in always-on nodes. | Choose when needing second-source availability with identical pinout and nearly identical AC/DC specs. |
Compared with SN74LVC04APW and 74AHC04PW, the MC74VHC04DT offers superior 7 V input tolerance for mixed-voltage interface integrity and lowest quiescent current for energy-constrained applications, while maintaining full pin and functional compatibility with industry-standard hex inverters.

FAQ
What is the maximum input voltage rating for MC74VHC04DT?
The MC74VHC04DT supports DC input voltages from −0.5 V to +7.0 V, independent of VCC. This 7 V tolerance allows direct interfacing of 5 V logic outputs to a 3.3 V-powered MC74VHC04DT without external protection components, making it ideal for voltage translation in mixed-supply systems.
Can MC74VHC04DT operate at 2.0 V supply voltage?
Yes, MC74VHC04DT is fully specified to operate down to 2.0 V VCC across the full temperature range (−40 °C to +85 °C). At 2.0 V, it maintains valid logic thresholds (VIH ≥ 1.5 V, VIL ≤ 0.5 V) and delivers usable output drive (VOL ≤ 0.1 V at 50 μA), supporting ultra-low-voltage portable designs.
Is MC74VHC04DT pin-compatible with older 74HC04 devices?
Yes, MC74VHC04DT uses the same 14-pin TSSOP footprint and pinout as standard 74HC04 and 74LS04 devices. 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 in existing layouts with improved speed and noise immunity.
What is the thermal derating for MC74VHC04DT in TSSOP package?
The MC74VHC04DT TSSOP package (case 948G−01) has a power dissipation limit of 450 mW in still air, with thermal derating of −6.1 mW/°C above 65 °C ambient. This allows safe continuous operation up to +85 °C ambient when total device power remains below ~325 mW under worst-case loading.
Does MC74VHC04DT require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs on MC74VHC04DT must be tied to a valid logic level (VCC or GND) to prevent floating nodes, which can cause excessive ICC, oscillation, or increased EMI. The device does not include internal weak pull-ups or pull-downs; external termination is mandatory for all unconnected A1–A6 inputs.
