Product details
Overview
MC74LCXU04DR2G from onsemi is a low-voltage CMOS unbuffered hex inverter operating from 1.65 V to 5.5 V, featuring 5 V-tolerant inputs for mixed-voltage interfacing, near-zero static supply current (10 µA), propagation delay as low as 3.3 ns at 5 V, and SOIC-14 packaging. It serves as a level-shifting logic buffer in battery-powered microcontroller I/O expansion and industrial sensor interface circuits.
For engineers reviewing the MC74LCXU04DR2G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, true pin functions, real-world use cases, and validated alternative options - all confirmed against onsemi's official Rev. 13 datasheet (April 2026).
Technical Context
The MC74LCXU04DR2G implements six independent unbuffered inverter stages with high-impedance TTL-compatible inputs that reduce loading on upstream drivers, and LVTTL/LVCMOS-compatible outputs optimized for switching noise immunity. Its input voltage tolerance up to 5.5 V enables direct connection to legacy 5 V TTL logic without external level shifters.
Each inverter stage exhibits matched propagation delays (tPLH/tPHL ≤ 3.3 ns at VCC = 4.5–5.5 V) and low output skew (≤1.0 ns between outputs), supporting synchronous signal inversion in timing-critical digital subsystems. The device meets JEDEC JESD78 latchup immunity (>100 mA) and exceeds 2000 V HBM ESD rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains. |
| Input Voltage Tolerance | −0.5 V to +6.5 V - enables safe interfacing with 5 V TTL outputs without clamping diodes or external protection. |
| Propagation Delay | 3.3 ns max at VCC = 4.5–5.5 V - ensures sub-300 MHz toggle capability in clock distribution or data path inversion. |
| Static Supply Current | 10 µA typical - reduces quiescent power in always-on IoT node peripherals and sleep-mode subsystems. |
| Output Drive | ±24 mA - sufficient to drive 50 pF loads with <1 ns edge jitter and minimal ground bounce in PCB traces. |
| Input Leakage | ±5.0 µA max at VCC = 3.6 V - preserves signal integrity in high-impedance sensor conditioning paths. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial PLC backplanes. |
Pinout & Package
MC74LCXU04DR2G is supplied in a Pb-free SOIC-14 (Case 751A) package measuring 8.75 mm × 3.90 mm × 1.75 mm, with 1.27 mm pitch and gull-wing leads suitable for reflow soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data Input (A0–A5) | Unbuffered CMOS input nodes accepting 0–5.5 V logic levels; must be tied to VCC or GND if unused. |
| 2, 4, 6, 8, 10, 12 | Inverted Output (O0–O5) | Push-pull CMOS outputs sourcing/sinking ±24 mA; no internal pull-ups or pull-downs. |
| 7 | GND | Dedicated ground reference for all six inverters; requires low-inductance PCB connection to minimize switching noise. |
| 14 | VCC | Single power supply rail for all logic stages; decoupling capacitor (0.1 µF ceramic) required within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V-tolerant inputs | Enables direct interconnection with 5 V TTL devices while powered from 1.8 V or 2.5 V rails - eliminates discrete level translators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unbuffered hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC04APWR | Lower max VCC (3.6 V); no 5 V input tolerance; 3.5 ns delay at 3.3 V. | Restricted to 3.3 V-only systems; cannot interface with 5 V logic without external clamping. | Select when cost is primary and system operates exclusively at ≤3.3 V with no legacy 5 V components. |
| 74LVCU04PW,118 | Same 1.65–5.5 V range and 5 V-tolerant inputs; TSSOP-14 package only; 3.7 ns delay at 5 V. | Requires PCB redesign for smaller footprint; identical functional behavior but different thermal resistance (150 °C/W vs 116 °C/W). | Choose for space-constrained designs where SOIC-14 layout is unavailable and thermal margin permits higher junction rise. |
Compared with MC74LCXU04DR2G, SN74LVC04APWR lacks 5 V input tolerance and limits system voltage flexibility, while 74LVCU04PW,118 matches electrical performance but trades SOIC-14 manufacturability for TSSOP-14 density - making MC74LCXU04DR2G optimal for mixed-voltage industrial boards requiring proven SOIC reliability and thermal headroom.

FAQ
What is the maximum input voltage rating for MC74LCXU04DR2G?
The MC74LCXU04DR2G supports DC input voltages from −0.5 V to +6.5 V, enabling safe operation with 5 V TTL signals even when powered from 1.65 V to 3.3 V supplies. This 5 V-tolerant input specification is explicitly guaranteed in the Absolute Maximum Ratings table of the onsemi datasheet Rev. 13.
Does MC74LCXU04DR2G require external pull-up or pull-down resistors on unused inputs?
Yes - per Section 3 of the onsemi datasheet, all unused inputs of MC74LCXU04DR2G must be tied to either VCC or GND to prevent floating states that could cause excessive current draw or erratic switching. The device has no internal termination, and leaving inputs unconnected violates recommended operating conditions.
What is the typical propagation delay of MC74LCXU04DR2G at 3.3 V supply?
At VCC = 3.0–3.6 V and TA = −40 °C to +85 °C, the MC74LCXU04DR2G exhibits a maximum propagation delay (tPLH/tPHL) of 3.6 ns, as specified in the AC Electrical Characteristics table. This value is measured under standard load conditions (CL = 50 pF, RL = 500 Ω) and confirms sub-278 MHz toggle capability.
Is MC74LCXU04DR2G suitable for automotive applications?
MC74LCXU04DR2G is not AEC-Q100 qualified, but its guaranteed operating temperature range (−40 °C to +125 °C), latchup immunity (>100 mA), and 2000 V HBM ESD rating make it suitable for non-safety-critical automotive body electronics such as door modules and lighting controls - provided system-level qualification is performed per OEM requirements.
What package type does MC74LCXU04DR2G use, and is it RoHS-compliant?
MC74LCXU04DR2G uses a Pb-free SOIC-14 package (Case 751A), as confirmed in the Ordering Information section of the datasheet. It is fully RoHS-compliant, halogen-free, and BFR-free, meeting EU Directive 2011/65/EU and JEDEC JS709E standards for environmentally conscious manufacturing.
