Product details
Overview
MC74VHCU04DT from ON Semiconductor is an unbuffered hex inverter IC designed for high-speed logic level translation and signal inversion in mixed-voltage systems. It operates across 2.0 V to 5.5 V, delivers 3.5 ns typical propagation delay at 5 V, supports 5 V ↔ 3 V interfacing via 7 V-tolerant inputs, and drives ±25 mA per output - used in bus buffering, clock conditioning, and digital control logic.
For engineers reviewing the MC74VHCU04DT datasheet, pinout, applications, or equivalent options, key selection criteria include its unbuffered architecture, rail-to-rail input tolerance, low ICC (2 µA max), balanced tPLH/tPHL, and TSSOP-14 package compatibility with standard logic families.
Technical Context
The MC74VHCU04DT implements six independent unbuffered CMOS inverters using silicon gate technology, enabling TTL-compatible speed without bipolar power penalties. Its input structure includes protection diodes rated for ±20 mA and 7 V absolute max input voltage, allowing safe interfacing between 3 V and 5 V domains without external level shifters.
All six inverters share a single VCC (Pin 14) and GND (Pin 7) supply pair, exhibit matched propagation delays (tPLH ≈ tPHL), and feature power-down input protection that prevents current flow when VCC = 0 V - critical for hot-swap and partial-power-down systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports wide-input-voltage operation in battery-powered and multi-rail systems. |
| tPD (Typ) | 3.5 ns at VCC = 5 V, CL = 15 pF - enables >100 MHz toggle rates in clean digital paths. |
| Input Voltage Max | 7.0 V - permits direct connection to 5 V buses while powered from 3.3 V or 2.5 V supplies. |
| IOUT (per pin) | ±25 mA - sufficient to drive multiple 74-series inputs or small capacitive loads without buffers. |
| ICC (Max) | 2 µA at TA = 25°C - ultra-low static power ideal for always-on logic and energy-sensitive applications. |
| VIH/VIL Thresholds | VIL ≤ 0.3×VCC, VIH ≥ 0.8×VCC - provides 20% noise margin across full VCC range for robust noise immunity. |
| ESD Rating | HBM > 2000 V - meets industrial handling requirements without additional protection circuitry. |
Pinout & Package
MC74VHCU04DT is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP), case 948G–01, with 0.65 mm lead pitch and exposed pad not connected. Pin 1 is marked by a beveled corner; device orientation follows JEDEC MO-153.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Inverter Input (A1–A6) | CMOS inputs with 7 V tolerance and ±0.1 µA leakage - accept TTL/CMOS/LVTTL logic levels. |
| 2, 4, 6, 8, 10, 12 | Inverter Output (Y1–Y6) | Push-pull CMOS outputs capable of sourcing/sinking ±25 mA - drive transmission lines or fan-out loads. |
| 7 | GND | Ground reference for all logic and power paths; must be low-impedance for noise control. |
| 14 | VCC | Primary supply rail (2.0–5.5 V); decoupling capacitor (0.1 µF) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered Inverter Architecture | Eliminates added delay and phase shift from internal buffering - preserves edge fidelity for timing-critical paths. |
| Input Voltage Tolerance | Supports 7 V max input regardless of VCC - enables safe 5 V signal injection into 3.3 V or 2.5 V systems. |
| Power-Down Input Protection | Inputs remain high-impedance and non-latching when VCC = 0 V - prevents backfeeding and latch-up during power sequencing. |
| Latch-Up Immunity | Exceeds 300 mA per JEDEC JESD78 - ensures robustness against transient overcurrent events in noisy environments. |
| Low Dynamic Noise (VOLP) | 0.8 V max quiet-output dynamic noise at VCC = 5 V - reduces crosstalk in dense PCB layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unbuffered 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; no 7 V input tolerance. | Restricted to single-supply 3.3 V systems; unsuitable for 5 V ↔ 3 V interfacing. | Select when operating exclusively at 3.3 V and board space favors PW (TSSOP) footprint compatibility. |
| 74AHC04PW | Wider VCC (2–5.5 V); 5.2 ns tPD at 5 V; 6 V max input rating (not 7 V). | Marginally slower and less tolerant on input overvoltage - requires external clamping for 5 V signal injection into 3 V rails. | Choose where cost sensitivity outweighs need for 7 V tolerance and sub-4 ns speed at 5 V. |
Compared with SN74LVC04APW and 74AHC04PW, the MC74VHCU04DT uniquely combines 7 V input tolerance, 3.5 ns speed at 5 V, and 2 µA quiescent current - making it optimal for mixed-voltage industrial and automotive control logic where interface robustness and timing precision coexist.

FAQ
What is the maximum input voltage rating for MC74VHCU04DT?
The MC74VHCU04DT supports DC input voltages up to 7.0 V, independent of VCC level. This allows direct connection of 5 V signals to the device even when powered from 2.5 V or 3.3 V supplies - a key enabler for mixed-voltage system design without external level shifters. Absolute maximum ratings specify –0.5 V to +7.0 V on any input pin.
Does MC74VHCU04DT support partial power-down operation?
Yes, the MC74VHCU04DT features power-down input protection: when VCC = 0 V, inputs remain high-impedance and do not sink or source current, preventing backfeeding or unintended logic states. This behavior is confirmed in the datasheet's "Power Down Protection Provided on Inputs" feature and supports safe hot-swap and power-sequencing scenarios.
What is the output drive capability of MC74VHCU04DT per inverter?
Each inverter output of the MC74VHCU04DT can source or sink up to ±25 mA continuously, as specified under DC Electrical Characteristics. This drive strength supports fan-out to multiple 74-series loads or direct driving of small-signal MOSFET gates and LEDs - verified at VCC = 5.0 V with VOL ≤ 0.44 V at IOL = 8 mA.
Is MC74VHCU04DT pin-compatible with other hex inverter packages?
Yes, the MC74VHCU04DT in TSSOP-14 (DT suffix) is pin- and function-compatible with industry-standard hex inverters including 74HC04, 74HCT04, and SN74LVC04A in the same 14-lead TSSOP outline. Pin numbering, logic function, and supply pin locations (Pin 7 = GND, Pin 14 = VCC) match JEDEC-standard assignments.
What is the typical propagation delay of MC74VHCU04DT at 3.3 V operation?
At VCC = 3.3 V and CL = 15 pF, the MC74VHCU04DT exhibits a typical propagation delay (tPLH/tPHL) of 5.0 ns, as documented in the AC Electrical Characteristics table. This value is measured under controlled conditions (input tr/tf = 3.0 ns) and reflects real-world performance in 3.3 V digital systems with moderate capacitive loading.
