Product details
Overview
MC74LVXU04DG from onsemi is an unbuffered hex inverter IC designed for level-shifting and signal inversion in mixed-voltage digital systems. It operates from 2.0 V to 3.6 V, tolerates 5.5 V inputs, delivers 4.1 ns typical propagation delay at 3.3 V, supports ±25 mA output drive, and features input power-down protection - enabling reliable interface between 3.0 V logic and legacy 5.0 V subsystems in industrial control and portable instrumentation.
For engineers reviewing the MC74LVXU04DG datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SOIC-14 and TSSOP-14 package mapping, confirmed AC/DC electrical specs, real-world use cases with design-value context, and two validated alternative parts with documented functional and application-level differences.
Technical Context
This device implements six independent CMOS inverter stages without internal buffering, resulting in matched tPLH/tPHL delays and low output skew (≤1.5 ns). Its input structure accepts voltages up to 5.5 V independent of VCC, enabling direct connection to 5 V buses while powered from 3.3 V or 2.7 V rails.
It exhibits rail-to-rail output swing, low dynamic noise (VOLP ≤ 0.5 V), and guaranteed latch-up immunity (±300 mA) per JEDEC JESD78. The design omits internal clamping diodes to ground/VCC, relying instead on external protection where needed - consistent with unbuffered logic architecture.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 3.6 V - Enables operation in modern low-voltage microcontroller I/O domains while maintaining compatibility with 3.3 V supply rails. |
| Input Voltage Tolerance | 0 V to 5.5 V - Allows safe interfacing with 5 V TTL or CMOS outputs without external level shifters or resistive dividers. |
| tPD (Typ) | 4.1 ns at VCC = 3.3 V, CL = 15 pF - Supports >100 MHz toggle rates in high-speed control logic paths with predictable timing margins. |
| IOUT (Sink/Source) | ±25 mA - Drives standard 50 Ω transmission lines or multiple 74-series inputs without external buffers. |
| VOL / VOH | 0.1 V / 2.58 V at IOL = 4 mA, VCC = 3.0 V - Ensures robust noise margin (>0.7 V) against 3.3 V LVTTL thresholds under full load. |
| ICC (Max) | 2.0 µA at TA = 25°C - Minimizes quiescent current in battery-powered or always-on monitoring circuits. |
| ESD Rating | >2000 V HBM - Provides baseline ESD resilience during board handling and in-field service without additional protection circuitry. |
Pinout & Package
MC74LVXU04DG is supplied in a Pb-free SOIC-14 NB (Case 751A) package with 1.27 mm pitch, 8.75 mm × 3.90 mm body, and 1.75 mm max height. Pin 1 is marked by a beveled corner or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A0 (Input) | Inverter stage 0 input - Accepts 0–5.5 V logic signals; must be tied HIGH or LOW (no floating inputs). |
| 2 | O0 (Output) | Inverter stage 0 output - Delivers rail-to-rail inverted logic with ±25 mA drive capability. |
| 3 | A1 (Input) | Inverter stage 1 input - Electrically identical to Pin 1; shares same VIH/VIL thresholds and noise immunity. |
| 4 | O1 (Output) | Inverter stage 1 output - Matches O0 timing (tPLH/tPHL skew ≤1.5 ns) for synchronized multi-channel inversion. |
| 5 | A2 (Input) | Inverter stage 2 input - Supports same 5.5 V tolerant operation as A0/A1; no internal pull-up/down. |
| 6 | O2 (Output) | Inverter stage 2 output - Validated for simultaneous switching with other outputs under CL = 50 pF load. |
| 7 | GND | Ground reference - Must be connected to system 0 V plane; serves as return path for all six inverter outputs. |
| 8 | O3 (Output) | Inverter stage 3 output - Shares same VOLP (≤0.5 V) and VIHD (≥2.0 V) noise specifications as O0–O2. |
| 9 | A3 (Input) | Inverter stage 3 input - Input leakage ≤±1.0 µA at VCC = 3.6 V ensures minimal loading on driving sources. |
| 10 | O4 (Output) | Inverter stage 4 output - Guaranteed to meet tPLH/tPHL limits across −40°C to +85°C operating range. |
| 11 | A4 (Input) | Inverter stage 4 input - Complies with JEDEC JESD8-12E input voltage thresholds for 3.3 V logic families. |
| 12 | O5 (Output) | Inverter stage 5 output - Final output; matches propagation delay distribution of earlier stages (±1.0 ns typical variation). |
| 13 | A5 (Input) | Inverter stage 5 input - Last input; requires same external biasing as Pins 1/3/5/9/11 to prevent undefined states. |
| 14 | VCC | Positive supply - Supplies all six inverters; decoupling capacitor (0.1 µF) required within 10 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered architecture | Eliminates added propagation delay and enables precise matching between inverter stages (tOSHL/tOSLH ≤1.5 ns). |
| 5.5 V-tolerant inputs | Permits direct connection to 5 V microcontrollers, sensors, or legacy peripherals without level-shifting components. |
| Low dynamic noise (VOLP ≤ 0.5 V) | Reduces crosstalk risk in dense PCB layouts with adjacent high-speed signal traces or analog sections. |
| Power-down input protection | Prevents back-powering or latch-up when VCC = 0 V but input signals remain active - critical for hot-swap applications. |

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 | Buffered architecture; 3.3 V only (no 5.5 V input tolerance); tPD = 4.5 ns (typ) at 3.3 V. | Lacks 5 V-tolerant inputs - requires external level shifting when interfacing with 5 V sources. | Select when system uses only 3.3 V logic and board space allows separate level translation. |
| 74AHC04PW,118 | Wider VCC range (2.0–5.5 V); higher drive (±8 mA); tPD = 5.3 ns (typ) at 5 V; not 5.5 V input tolerant. | Requires VCC = 5 V to achieve full 5 V output swing - incompatible with mixed 3.3 V/5 V supply domains. | Select when all logic operates at 5 V and lower propagation delay is not critical. |
Compared with MC74LVXU04DG, SN74LVC04APWR lacks input voltage tolerance for 5 V interfaces, while 74AHC04PW,118 mandates 5 V supply to reach full output swing - making MC74LVXU04DG uniquely suited for 3.3 V systems requiring direct 5 V signal acceptance without layout or supply changes.

FAQ
What is the maximum input voltage rating for MC74LVXU04DG?
The MC74LVXU04DG supports DC input voltages from −0.5 V to +5.5 V, independent of VCC. This 5.5 V tolerance allows direct connection to 5 V logic sources even when powered from 2.0–3.6 V supplies - a key feature confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official onsemi datasheet.
Does MC74LVXU04DG require external pull-up or pull-down resistors on unused inputs?
Yes - the MC74LVXU04DG datasheet explicitly states that unused inputs must not be left open and must be tied to a valid logic HIGH or LOW voltage level. Floating inputs can cause increased ICC, unpredictable output states, or excessive power dissipation due to intermediate input voltage conditions activating both PMOS and NMOS transistors simultaneously.
What package types are available for MC74LVXU04DG?
MC74LVXU04DG is offered exclusively in the Pb-free SOIC-14 NB (Case 751A) package, with dimensions 8.75 mm × 3.90 mm × 1.75 mm and 1.27 mm lead pitch. While the base part number MC74LVXU04 is also available in TSSOP-14 (e.g., MC74LVXU04DTR2G), the DG suffix specifically denotes the SOIC-14 NB variant per onsemi's ordering information table.
Is MC74LVXU04DG suitable for automotive applications?
MC74LVXU04DG is rated for −40°C to +85°C operation and meets JEDEC JESD78 latch-up immunity (±300 mA), but it is not AEC-Q200 qualified. It may be used in non-safety-critical automotive body electronics where extended temperature performance is required, though designers should verify qualification status with onsemi for specific vehicle program compliance.
How does the unbuffered architecture of MC74LVXU04DG affect its timing behavior?
The unbuffered design of MC74LVXU04DG eliminates internal staging, resulting in inherently matched propagation delays across all six inverters (tOSHL/tOSLH ≤1.5 ns). This yields tighter output-to-output skew than buffered hex inverters - a measurable advantage in synchronous signal conditioning, clock domain crossing, or multi-channel edge alignment tasks.
