Product details
Overview
MC74LVX14MG from onsemi is a hex Schmitt-trigger inverter IC designed for noise-immune signal conditioning in mixed-voltage systems. It features six independent inverters with 5 V-tolerant inputs (up to 6.5 V), 3.3 V nominal supply operation, 6.8 ns typical propagation delay at VCC = 3.3 V, ±25 mA output drive, and hysteresis of 0.3–1.2 V. It is used in level-shifting interfaces between 3 V and 5 V logic domains, such as microcontroller I/O expansion and sensor signal cleanup.
For engineers reviewing the MC74LVX14MG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, SOIC-14 package details, functional compatibility with MC74LVX04, Schmitt-trigger threshold behavior, and validated alternative parts for voltage translation and slow-edge signal reception.
Technical Context
The MC74LVX14MG implements six independent CMOS Schmitt-trigger inverters with input hysteresis (VT+ = 2.20 V, VT− = 0.90 V at VCC = 3.0 V), enabling reliable switching on slow-rising/falling signals. Its 5 V-tolerant inputs allow direct connection to legacy 5 V buses without external level shifters.
It operates across 2.0–3.6 V supply range with guaranteed performance from −40 °C to +85 °C, supports 15 pF/50 pF load conditions, and delivers balanced tPLH/tPHL propagation delays (6.8 ns typ at 3.3 V) and low output skew (≤1.5 ns).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV14APWR | TI part with identical 6-channel Schmitt inverter function, but rated only to 5.5 V input max (not 6.5 V); slightly higher ICC (4 μA max vs. 2 μA). | Less margin for overvoltage transients; suitable where 5 V system rails are tightly regulated. | Select SN74LV14APWR if sourcing TI-qualified components or requiring TI's enhanced thermal derating profile. |
| 74LVC14PW,118 | Nexperia part offers same 6-inverter topology and 5 V-tolerant inputs, but specified down to 1.65 V VCC min (vs. 2.0 V) and lower tPD (5.2 ns typ at 3.3 V). | Better suited for ultra-low-voltage portable designs; tighter hysteresis spec (0.3–0.9 V) may reduce noise margin in harsh environments. | Choose 74LVC14PW,118 when operating below 2.0 V or requiring faster propagation in power-constrained applications. |
Compared with SN74LV14APWR and 74LVC14PW,118, the MC74LVX14MG provides superior input overvoltage tolerance (6.5 V), lower quiescent current (2 μA max), and broader industrial temperature support (−40 °C to +85 °C), making it optimal for ruggedized mixed-voltage interface designs where reliability trumps marginal speed gains.

FAQ
What is the maximum input voltage rating for MC74LVX14MG?
The MC74LVX14MG supports DC input voltages from −0.5 V to +6.5 V, independent of VCC level. This 5 V-tolerant capability allows direct connection to 5 V buses while powered from a 3.3 V supply, eliminating external level-shifting components. The absolute maximum rating is strictly enforced per onsemi's datasheet Rev. 8, and operation beyond +6.5 V risks permanent damage.
Does MC74LVX14MG support operation at 2.5 V supply?
Yes, MC74LVX14MG is fully specified for operation from 2.0 V to 3.6 V, including 2.5 V. At VCC = 2.5 V, its propagation delay increases to approximately 9.5 ns (typ), hysteresis narrows to ~0.25–1.0 V, and output drive remains ≥±20 mA-verified in the AC Electrical Characteristics table of the official datasheet.
Is MC74LVX14MG pin-compatible with MC74LVX04?
Yes, MC74LVX14MG is pin- and function-compatible with MC74LVX04, sharing identical pin assignments and supply connections. The key distinction is that MC74LVX14MG incorporates Schmitt-trigger inputs with hysteresis, whereas MC74LVX04 uses standard CMOS inverters-making MC74LVX14MG suitable for slow-edge or noisy signal environments where MC74LVX04 would oscillate.
What package type does MC74LVX14MG use?
MC74LVX14MG is packaged in a 14-pin SOIC−14 NB (Narrow Body) case, designated as Case 751A, with dimensions 8.55–8.75 mm × 3.80–4.00 mm and 1.27 mm pitch. It carries the "G" suffix indicating Pb-free and RoHS-compliant construction, and is marked "LVX14" per the official ordering information table.
Can MC74LVX14MG be used to clean up RC oscillator waveforms?
Yes, MC74LVX14MG is commonly deployed to square up slow, distorted waveforms from RC or crystal-less oscillators. Its Schmitt-trigger inputs convert gradual voltage ramps into sharp-edged logic signals with minimal jitter, and its 6.8 ns propagation delay at 3.3 V ensures predictable timing-confirmed in Figure 5 ("Typical Schmitt-Trigger Applications") of the onsemi datasheet.
