Product details
Overview
MC74LVX08DR2 from onsemi is a quad 2-input AND gate IC designed for level-shifting logic interfacing between 3.0 V and 5.0 V systems, featuring 5 V-tolerant inputs (up to 6.5 V), 4.8 ns typical propagation delay at 3.3 V, ±25 mA output drive, and SOIC-14 package. It serves as a voltage-compatible combinational logic buffer in mixed-voltage digital control subsystems.
For engineers reviewing the MC74LVX08DR2 datasheet, pinout, applications, or equivalent options, key selection criteria include input voltage tolerance, propagation delay vs. supply voltage, output drive capability under load, and SOIC-14 footprint compatibility with legacy 74-series logic designs.
Technical Context
The MC74LVX08DR2 implements four independent 2-input AND gates in a single CMOS device with rail-to-rail input tolerance - inputs accept DC voltages from −0.5 V to +6.5 V regardless of VCC (2.0–3.6 V), enabling safe connection to 5 V buses while operating from 3.3 V supplies. Its balanced tPLH/tPHL delays ensure minimal skew across outputs.
It delivers low-noise switching performance (VOLP ≤ 0.5 V) and latch-up immunity exceeding 300 mA, meeting stringent industrial reliability requirements. Power-down protection on all inputs prevents back-driving damage when VCC = 0 V, supporting hot-swap and partial-power-down system architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 3.6 V - supports standard 3.3 V logic rails with 10% margin; not rated for 5 V operation |
| Input Voltage Tolerance | −0.5 V to +6.5 V - enables direct interface to 5 V microcontrollers, sensors, or legacy peripherals without external level shifters |
| tPD (Typ) | 4.8 ns at VCC = 3.3 V, CL = 15 pF - ensures sub-5 ns timing for high-speed control signal gating in real-time systems |
| IOUT (Max) | ±25 mA per output - drives standard TTL loads or multiple 74LVC inputs without buffering |
| VOL (Max) | 0.44 V at IOL = 4 mA, VCC = 3.0 V - guarantees solid LOW-level recognition by downstream 3.3 V CMOS receivers |
| VIH/VIL | VIH = 2.0 V min, VIL = 0.8 V max at VCC = 3.0 V - provides 0.7 V noise margin for robust static logic discrimination |
| ESD Rating | HBM > 2000 V - meets industrial handling requirements without additional ESD protection circuitry |
Pinout & Package
MC74LVX08DR2 is housed in a 14-pin SOIC-NB (Small Outline Integrated Circuit – Narrow Body) package, case 751A, with 1.27 mm pitch, 8.75 mm × 3.90 mm body, and gull-wing leads. Pin 1 is marked by a beveled corner or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | A0–A3 (Data Input A) | First input of each AND gate; 5 V-tolerant, accepts 0–6.5 V |
| 2, 5, 12, 9 | B0–B3 (Data Input B) | Second input of each AND gate; identical voltage tolerance and loading |
| 3, 6, 11, 8 | O0–O3 (Output) | CMOS push-pull outputs; sink/source up to ±25 mA; VOL/VOH specified at 4 mA |
| 7 | GND | Ground reference for all logic and power domains; must be low-impedance |
| 14 | VCC | Positive supply (2.0–3.6 V only); decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| 5 V–Tolerant Inputs | Enables direct connection to 5 V buses while powered from 3.3 V, eliminating discrete level translators in mixed-voltage I/O subsystems |
| Low Propagation Skew | tOSHL/tOSLH ≤ 1.5 ns - critical for synchronous enable/gating of parallel data paths or clock distribution networks |
| Power-Down Input Protection | Inputs remain high-impedance and non-latching when VCC = 0 V, preventing back-current injection during partial power sequencing |
| Low Dynamic Noise | VOLP ≤ 0.5 V - reduces crosstalk and ground bounce in dense PCB layouts with shared return paths |
| Pb-Free & RoHS Compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (J-STD-020) |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC08APWR | 3.3 V only inputs (max Vin = VCC + 0.5 V); no 5 V tolerance | Requires external level shifters for 5 V interface; lower ICC (1 μA typ) | Select when full system operates at 3.3 V and ultra-low quiescent current is prioritized over interface flexibility |
| 74AHC08D,118 | Wider VCC range (2–5.5 V); inputs tolerate only up to VCC + 0.5 V | Can operate directly from 5 V supply but cannot safely interface 5 V signals while running at 3.3 V | Select when system uses single 5 V rail and higher speed (tPD = 3.5 ns @ 5 V) is needed over mixed-voltage support |
Compared with SN74LVC08APWR and 74AHC08D,118, the MC74LVX08DR2 uniquely supports 5 V signal interfacing while powered from 3.3 V - a capability absent in both alternatives - making it the only choice for voltage-domain bridging without added components.

FAQ
What is the maximum input voltage rating for MC74LVX08DR2?
The MC74LVX08DR2 supports DC input voltages from −0.5 V to +6.5 V, independent of VCC. This 5 V–tolerant feature allows direct connection to 5 V signal sources even when powered from a 3.3 V supply - a key differentiator versus standard LVC or AHC logic families. The absolute maximum rating is strictly limited to 6.5 V; exceeding this risks permanent damage.
Can MC74LVX08DR2 operate with a 5 V supply voltage?
No, MC74LVX08DR2 is not rated for 5 V VCC operation. Its recommended VCC range is 2.0 V to 3.6 V. Applying 5 V to VCC violates the Absolute Maximum Rating (VCC ≤ +6.5 V is a damage threshold, not an operating condition) and will cause excessive ICC, thermal stress, and potential functional failure. Use 74AHC08 or 74AC08 for true 5 V supply operation.
Does MC74LVX08DR2 support hot insertion when VCC = 0 V?
Yes, MC74LVX08DR2 includes power-down protection on all inputs. When VCC = 0 V, inputs remain high-impedance and do not sink or source current, preventing back-driving of the 5 V bus or damage to upstream drivers. This behavior is verified in the datasheet's "Power Down Protection" feature and confirmed by IIK limits (−20 mA max).
What is the output drive strength of MC74LVX08DR2 at 3.3 V?
At VCC = 3.3 V, MC74LVX08DR2 guarantees ±25 mA DC output current per pin (IOUT). VOH is specified at IOH = −4 mA (≥2.58 V), and VOL at IOL = 4 mA (≤0.1 V), confirming robust drive into standard TTL or multiple CMOS loads. This eliminates need for external buffers in most industrial interface applications.
Is MC74LVX08DR2 pin-compatible with standard 74-series AND gates?
Yes, MC74LVX08DR2 uses the industry-standard SOIC-14 pinout for quad 2-input AND gates (e.g., 74LS08, 74HC08, 74LVC08), with identical pin assignments: pins 1–2–3 for Gate 0, 4–5–6 for Gate 1, 10–9–8 for Gate 3, and 13–12–11 for Gate 2, plus VCC (14) and GND (7). This enables drop-in replacement in existing layouts where voltage tolerance and speed meet design needs.
