Product details
Overview
MC74LVX50DG from onsemi is a hex non-inverting buffer IC designed for level-shifting and noise-immune signal distribution in mixed-voltage systems. It features six independent buffer channels, operates from 2.0 V to 3.6 V, delivers 4.1 ns typical propagation delay at 3.3 V, tolerates 5.0 V inputs up to 6.5 V, and supports industrial temperature range (−40°C to +85°C). It is used in digital logic interfacing between 3.3 V microcontrollers and 5 V peripherals.
For engineers reviewing the MC74LVX50DG datasheet, pinout, applications, or equivalent options, key selection considerations include input overvoltage tolerance, propagation delay matching across channels, output drive capability (±4 mA), power-down input protection, and compatibility with SOIC-14 NB packaging for legacy board layouts.
Technical Context
The MC74LVX50DG implements three-stage CMOS buffering per channel to ensure high noise immunity and stable output transitions. Its input structure accepts voltages up to 6.5 V regardless of VCC, enabling robust 5 V-to-3.3 V interface without external level shifters.
All six buffers are electrically isolated with balanced tPLH/tPHL delays and ≤1.5 ns output-to-output skew under matched load conditions. The device includes power-down protection that prevents current backflow when VCC = 0 V, safeguarding upstream drivers during partial power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 3.6 V - Ensures compatibility with modern low-voltage logic families while maintaining margin against supply ripple. |
| Input Voltage Tolerance | Up to 6.5 V - Allows direct connection to 5 V TTL/CMOS outputs without clamping diodes or resistors. |
| Propagation Delay (tPD) | 4.1 ns typ @ VCC = 3.3 V, CL = 15 pF - Enables reliable operation in sub-100 MHz digital control paths. |
| Output Drive Strength | ±4 mA @ VOH/VOL - Sufficient to drive standard CMOS loads and short PCB traces without signal degradation. |
| Input Leakage Current | ±1.0 µA max @ TA ≤ 85°C - Minimizes static power loss and avoids unintended logic state shifts in high-impedance nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC50AQPWRQ1 | Automotive-grade AEC-Q100 qualified; identical 2.0–3.6 V range but tighter VIH/VIL specs (1.7 V/0.7 V min/max) and higher ICC (10 µA max). | Required for automotive safety-critical domains where qualification and extended temperature (−40°C to +125°C) are mandatory. | Select when AEC-Q100 compliance and extended junction temperature operation are required; not drop-in due to different thermal derating and qualification testing. |
| 74LVX50M | Same functional spec and pinout; manufactured by ON Semiconductor under alternate marking (no G suffix), same SOIC-14 package but may lack explicit Pb-free certification documentation. | Suitable for cost-sensitive industrial designs where RoHS compliance is not enforced, and legacy procurement channels prefer non-G part numbers. | Valid alternative if Pb-free status is not audited; verify latest MSL and moisture sensitivity labeling before use in high-reliability reflow processes. |
Compared with SN74LVC50AQPWRQ1 and 74LVX50M, the MC74LVX50DG offers verified Pb-free compliance, industrial temperature support, and documented 6.5 V input tolerance-making it optimal for commercial and industrial systems requiring assured environmental conformance and interoperability with 5 V logic without redesign.

FAQ
What is the maximum input voltage the MC74LVX50DG can tolerate?
The MC74LVX50DG supports DC input voltages up to 6.5 V regardless of VCC level, enabling direct interface with 5 V logic families without external level-shifting components. This specification is guaranteed across the full operating temperature range (−40°C to +85°C) and is validated per the Absolute Maximum Ratings table in the official datasheet.
Does the MC74LVX50DG support power-down protection?
Yes, the MC74LVX50DG includes built-in power-down protection on all inputs. When VCC = 0 V, the inputs remain high-impedance and do not sink or source current, preventing back-driving of upstream devices during partial power sequencing or hot-swap scenarios. This feature eliminates the need for external isolation diodes in many system architectures.
What is the output drive capability of the MC74LVX50DG?
The MC74LVX50DG provides ±4 mA output drive strength per channel at VOH and VOL, measured under standard test conditions (VCC = 3.0 V, TA = 25°C). This allows reliable driving of typical CMOS loads, including multiple gate inputs and moderate PCB trace capacitance, without signal degradation or excessive rise/fall time penalties.
Is the MC74LVX50DG pin-compatible with other hex buffer ICs?
The MC74LVX50DG uses the industry-standard SOIC-14 NB pinout for hex non-inverting buffers, matching pin assignments of functionally similar devices like the 74LVX50 and SN74LVC50A. However, differences in input threshold levels, drive strength, and overvoltage tolerance mean electrical compatibility must be verified per application; it is not a guaranteed drop-in replacement for all variants.
What package type is used for the MC74LVX50DG?
The MC74LVX50DG is packaged in SOIC-14 NB (Case 751A), a 14-pin small-outline integrated circuit with 1.27 mm pitch, 8.75 mm × 3.90 mm body dimensions, and Pb-free (RoHS-compliant) finish. This package is compatible with standard surface-mount assembly processes and widely supported in legacy and new industrial PCB designs.
