Product details
Overview
MC74VHCU04DTR2 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 across 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, and is AEC-Q100 qualified for automotive applications.
For engineers reviewing the MC74VHCU04DTR2 datasheet, pinout, applications, or equivalent options, this page provides verified technical context, real-world design meaning of key specs, TSSOP-14 package details, functional alternatives, and supply support for industrial and automotive embedded designs.
Technical Context
The MC74VHCU04DTR2 implements six independent unbuffered inverter stages using silicon-gate CMOS technology, achieving TTL-compatible speed without bipolar power penalties. Its inputs tolerate up to 5.5 V regardless of VCC, enabling robust level-shifting between 3.0 V and 5.0 V domains without external resistors or translators.
Each inverter exhibits balanced tPLH/tPHL propagation delays (±1.0 ns max mismatch), low dynamic noise (VOLP ≤ 0.8 V), and input protection against latchup (>100 mA) and ESD (>2000 V HBM). It operates from −40°C to +85°C with guaranteed VIH/VIL thresholds referenced to VCC (e.g., VIH ≥ 0.8 × VCC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Hex unbuffered inverter - no internal buffering; minimal propagation delay but reduced drive strength vs buffered variants |
| Supply Voltage Range | 2.0 V to 5.5 V - supports single-supply operation across 3.3 V and 5 V systems, including partial-power-down scenarios |
| Propagation Delay (tPD) | 3.5 ns typical at VCC = 5.0 V, CL = 15 pF - enables >100 MHz toggle rates in clean PCB layouts |
| Input Voltage Tolerance | −0.5 V to +6.5 V - allows safe connection to 5 V signals even when powered from 3.3 V or 2.5 V rails |
| Output Drive Current | ±8 mA at VCC = 4.5 V - sufficient for driving multiple CMOS loads or short PCB traces, not intended for bus termination |
| Quiescent ICC | 2.0 µA max at TA = 25°C - enables ultra-low static power in battery-backed or always-on subsystems |
| Operating Temperature | −40°C to +85°C - qualified for under-hood automotive and industrial control environments |
Pinout & Package
TSSOP-14 (Case 948G, DT suffix), 4.4 mm × 5.0 mm body, 0.65 mm pitch, lead-free (Pb-free) and RoHS compliant. Pin 1 marked by notch or dot; exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 (Input) | Inverter stage 1 input - accepts 0–5.5 V logic levels independent of VCC |
| 2 | Y1 (Output) | Inverter stage 1 output - complements A1 with rail-to-rail swing (0 V to VCC) |
| 3 | A2 (Input) | Inverter stage 2 input - electrically isolated from other inputs; no internal sharing |
| 4 | Y2 (Output) | Inverter stage 2 output - identical timing and drive capability as Y1 |
| 5 | A3 (Input) | Inverter stage 3 input - supports same voltage tolerance and noise immunity as A1/A2 |
| 6 | Y3 (Output) | Inverter stage 3 output - balanced delay ensures synchronous inversion across all six channels |
| 7 | GND | Ground reference - must be low-impedance connection; decoupling capacitor required near pin |
| 8 | Y4 (Output) | Inverter stage 4 output - shares same VCC/GND pair; layout symmetry recommended |
| 9 | A4 (Input) | Inverter stage 4 input - no internal pull-up/down; unused inputs must be tied to VCC or GND |
| 10 | Y5 (Output) | Inverter stage 5 output - VOL ≤ 0.36 V at IOL = 4 mA ensures solid low-state margin |
| 11 | A5 (Input) | Inverter stage 5 input - immune to noise spikes ≥10% VCC due to high noise immunity spec |
| 12 | Y6 (Output) | Inverter stage 6 output - final output; matches VOH ≥ 4.0 V at IOH = −4 mA for 5 V logic high |
| 13 | A6 (Input) | Inverter stage 6 input - full 5.5 V tolerant; compatible with legacy 5 V microcontroller GPIO |
| 14 | VCC | Positive supply - bypass with 0.1 µF ceramic capacitor directly to GND (pin 7) |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered architecture | Eliminates added delay from internal buffers - critical for timing-critical feedback paths and oscillator circuits |
| 5.5 V-tolerant inputs | Enables direct connection to 5 V microcontrollers while operating from 3.3 V supply - no level shifter needed |
| Low dynamic noise (VOLP ≤ 0.8 V) | Reduces crosstalk risk in dense routing; maintains signal integrity when switching multiple outputs simultaneously |
| AEC-Q100 qualified (−Q variant) | Validated for automotive use including temperature cycling, HTOL, and ESD - meets PPAP documentation requirements |
| Latchup immunity >100 mA | Withstands transient overcurrent events without destructive latchup - improves system robustness in noisy environments |

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; non-automotive grade | Not AEC-Q100 qualified; lacks 5.5 V input tolerance - requires external clamping for 5 V inputs | Preferred for cost-sensitive consumer electronics where automotive qualification is unnecessary |
| 74AHC04PW,118 | Wider VCC range (2.0–5.5 V); 5.3 ns tPD at 5 V; higher ICC (4 µA max); no −Q automotive variant | Higher propagation delay and quiescent current; no PPAP support or automotive stress testing documentation | Suitable for industrial control where AEC-Q100 is not mandated but same footprint and voltage compatibility are required |
Compared with SN74LVC04APWR and 74AHC04PW,118, the MC74VHCU04DTR2 uniquely combines 5.5 V input tolerance, AEC-Q100 qualification, and 3.5 ns speed at 5 V - making it the only choice when automotive-grade level shifting with minimal delay is mandatory.

FAQ
What is the maximum input voltage rating for MC74VHCU04DTR2?
The MC74VHCU04DTR2 supports DC input voltages from −0.5 V to +6.5 V, independent of VCC. This allows safe interfacing with 5 V signals even when the device is powered from 3.3 V or 2.5 V supplies - a key advantage over standard LVC or HC logic families that clamp at VCC + 0.5 V.
Is MC74VHCU04DTR2 pin-compatible with other hex inverters like 74HC04?
Yes, MC74VHCU04DTR2 uses the industry-standard 14-pin TSSOP layout with identical pinout to 74HC04, 74AHC04, and SN74LVC04A. All six inverter inputs (A1–A6) and outputs (Y1–Y6), plus VCC and GND, occupy matching positions - enabling drop-in replacement in existing footprints when voltage and timing requirements align.
Does MC74VHCU04DTR2 require external pull-up or pull-down resistors on unused inputs?
Yes - per the datasheet, all unused inputs on MC74VHCU04DTR2 must be tied to a valid logic level (VCC or GND) to prevent floating nodes, increased ICC, and potential oscillation. The device does not include internal weak pull-ups or pull-downs, so external termination is mandatory for reliable operation.
What is the thermal resistance (θJA) of MC74VHCU04DTR2 in its TSSOP-14 package?
The MC74VHCU04DTR2 in TSSOP-14 (Case 948G) has a junction-to-ambient thermal resistance (θJA) of 150°C/W when mounted on a standard FR4 PCB with minimum copper pad spacing and no airflow - as specified in the Maximum Ratings table. This value assumes JEDEC JESD51-7 test conditions and guides thermal design for continuous operation at max ambient.
How does the unbuffered architecture of MC74VHCU04DTR2 affect its drive capability compared to buffered inverters?
The unbuffered design of MC74VHCU04DTR2 results in lower output drive strength (±4 mA at 3.3 V) versus buffered equivalents like MC74VHC04, but delivers faster propagation delay (3.5 ns vs ~4.5 ns) and lower capacitive loading. It is optimized for point-to-point inversion, not fanout-heavy bus driving - use buffered variants when driving >2 CMOS loads or longer traces.
