Product details
Overview
74VHCU04MTC from ON Semiconductor is a hex inverter IC fabricated in advanced high-speed CMOS silicon gate technology, delivering 3.5 ns typical propagation delay at 5 V, 2 µA max quiescent current at 25°C, and input voltage tolerance up to 7 V - enabling robust 5 V/3 V mixed-supply interfacing and crystal oscillator use.
For engineers reviewing the 74VHCU04MTC datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, TSSOP-14 package mapping, noise immunity specs (28% VCC), dynamic output limits (VOLP ≤ 0.8 V), and validated alternatives for logic-level translation and clock buffering designs.
Technical Context
The 74VHCU04MTC implements six independent single-stage CMOS inverters with input protection circuitry allowing –0.5 V to +7.0 V input voltage regardless of VCC, supporting battery-backup and dual-rail system interfacing. Its rail-to-rail input tolerance and low ICC enable direct connection between 3 V and 5 V domains without level shifters.
It operates across 2.0 V–5.5 V supply range with guaranteed performance from –40°C to +85°C. Propagation delay varies from 3.5 ns (typ., CL = 15 pF, VCC = 5 V) to 8.0 ns (max., CL = 50 pF, full temp range), and output drive capability is ±8 mA at VOH/VOL limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - supports operation across 3 V and 5 V logic systems without external regulation |
| Propagation Delay (tPD) | 3.5 ns (typ.) at VCC = 5 V, CL = 15 pF - enables high-speed signal inversion in timing-critical paths |
| Quiescent Supply Current (ICC) | 2 µA (max.) at TA = 25°C - ensures ultra-low static power in battery-powered or standby circuits |
| Input Voltage Range (VIN) | –0.5 V to +7.0 V - allows safe interfacing with overvoltage sources and mixed-supply nodes |
| Noise Immunity (VNIH/VNIL) | 28% VCC (min.) - provides strong rejection of coupled transients on logic inputs |
| Output Drive (IOL/IOH) | ±8 mA - sufficient to drive standard CMOS loads and small capacitive buses directly |
| Dynamic Output Noise (VOLP) | 0.8 V (max.) at CL = 50 pF - limits ground bounce during fast switching in dense PCB layouts |
Pinout & Package
74VHCU04MTC is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4 mm wide, with 0.65 mm lead pitch and gull-wing terminations. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Inverter Input (A1–A6) | CMOS-compatible digital inputs with ±20 mA diode current rating and –0.5 V to +7.0 V absolute max range |
| 2, 4, 6, 10, 12, 14 | Inverter Output (Y1–Y6) | Push-pull CMOS outputs capable of sourcing/sinking ±8 mA while maintaining VOL ≤ 0.5 V and VOH ≥ 4.0 V at VCC = 4.5 V |
| 7 | GND | Ground reference for all internal circuitry and I/O; must be connected to system ground plane |
| 14 | VCC | Positive supply terminal; decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Single-stage inverter topology | Enables analog use cases such as Pierce crystal oscillator feedback paths without added phase shift stages |
| Input overvoltage tolerance | Supports direct connection to 7 V sources (e.g., legacy TTL, battery monitors) even when VCC = 3.3 V |
| Power-down input protection | Prevents back-powering and latch-up when VCC = 0 V but inputs remain active - critical for hot-swap and partial-power-down systems |
| Low dynamic ground bounce | VOLP ≤ 0.8 V ensures minimal supply rail disturbance during simultaneous switching of multiple outputs |
| Pin/function compatibility | Direct drop-in replacement for 74HCU04 in existing SOIC-14 layouts when using adapter or redesign; identical logic function and truth table |
Applications
| Crystal Oscillator Buffer | Level Translation Interface |
|---|---|
|
Use Scenario: Driving Pierce crystal oscillator feedback loop in microcontroller clock generation circuits. IC Role / Device Role / Timing Role: Inverter stage providing 180° phase shift and gain for sustaining oscillation at fundamental frequency.

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 (1.65–3.6 V), 3.5 ns tPD at 3.3 V, ±24 mA drive, no 7 V input tolerance | Restricted to 3.3 V-only systems; unsuitable for 5 V interface or crystal oscillator use | Select when operating exclusively at 3.3 V and higher drive strength is needed; verify input voltage compliance |
| MC74VHC04DT | Same 2–5.5 V range and 7 V input rating, but 4.5 ns tPD (typ.), 1 µA ICC (max.), TSSOP-14 package | Near-identical functionality; slightly slower propagation but lower static current | Preferred for ultra-low-power standby modes where 1 ns delay penalty is acceptable |
Compared with SN74LVC04APW and MC74VHC04DT, the 74VHCU04MTC uniquely balances 5 V compatibility, 7 V input robustness, sub-4 ns speed, and µA-level quiescent draw - making it optimal for mixed-voltage clock distribution and fail-safe signal routing.

FAQ
What is the maximum input voltage rating for the 74VHCU04MTC?
The 74VHCU04MTC supports DC input voltages from –0.5 V to +7.0 V, independent of VCC level. This allows safe interfacing with higher-voltage sources like 5 V TTL outputs or battery monitors even when operating at 3.3 V. The specification is guaranteed per Absolute Maximum Ratings and confirmed in the datasheet's VIN parameter table.
Does the 74VHCU04MTC support operation at 3.3 V supply?
Yes, the 74VHCU04MTC operates across 2.0 V to 5.5 V, including 3.3 V nominal supply. At VCC = 3.3 V, it delivers guaranteed VOH ≥ 2.7 V and VOL ≤ 0.3 V under 4 mA load, with tPD ≤ 10.5 ns (max.) at CL = 50 pF and full temperature range. These values are specified in the Recommended Operating Conditions and DC Electrical Characteristics tables.
Is the 74VHCU04MTC pin-compatible with standard 74HCU04 devices?
Yes, the 74VHCU04MTC is pin and function compatible with the 74HCU04, sharing identical pinout (six inverters, GND, VCC) and truth table. However, due to its TSSOP-14 package (vs. SOIC-14 for many 74HCU04 variants), direct PCB replacement requires footprint adaptation unless the target board already uses TSSOP-14.
Can the 74VHCU04MTC be used in crystal oscillator circuits?
Yes, the 74VHCU04MTC is explicitly qualified for crystal oscillator use due to its single-stage inverter architecture, which provides precise 180° phase inversion without added delay stages. The datasheet confirms this application in the General Description section and cites stable oscillation in Pierce configurations with appropriate load capacitance.
What is the thermal and environmental operating range for the 74VHCU04MTC?
The 74VHCU04MTC is rated for continuous operation from –40°C to +85°C ambient temperature, with storage temperature spanning –65°C to +150°C. These limits are defined in the Recommended Operating Conditions and Absolute Maximum Ratings sections and apply to the MTC14 (TSSOP-14) package variant.
