Product details
Overview
MC74LCX00D from onsemi is a low-voltage CMOS quad 2-input NAND gate operating from 1.65 V to 5.5 V supply, featuring 5 V-tolerant inputs for mixed-voltage interfacing, 24 mA balanced output drive at 3.0 V, near-zero static supply current (10 µA), and AEC-Q100 qualification for automotive use. It serves as a level-shifting logic buffer in power-constrained digital control subsystems.
For engineers reviewing the MC74LCX00D datasheet, pinout, applications, or equivalent options, key selection considerations include its 5 V-tolerant input capability, SOIC-14 package compatibility, −40 °C to +125 °C operating range, and automotive-grade qualification status under AEC-Q100.
Technical Context
The MC74LCX00D implements four independent NAND gates with TTL-compatible inputs and outputs, enabling direct interface with legacy 5 V logic while powered from 1.65–5.5 V supplies. Its VIH/VIL thresholds scale with VCC across voltage ranges (e.g., VIH = 0.65×VCC at 1.65–1.95 V; 0.70×VCC at 4.5–5.5 V), ensuring robust noise margins.
Propagation delay is specified from 4.2 ns (at 4.5–5.5 V) to 10 ns (at 1.65–1.95 V), with output-to-output skew ≤1.0 ns at 3.0–3.6 V. The device supports tri-state behavior only via external gating - it has no internal enable or bus-hold circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables operation across LVTTL, LVCMOS, and mixed-voltage systems without level shifters. |
| Input Voltage Tolerance | −0.5 V to +6.5 V - allows safe connection to 5 V TTL outputs even when VCC = 1.65 V. |
| Output Drive Strength | ±24 mA @ 3.0 V - sufficient to drive multiple LVTTL loads or moderate-capacitance PCB traces directly. |
| Quiescent Supply Current | 10 µA max - minimizes standby power in battery-backed or always-on control logic. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive and industrial environments. |
| Propagation Delay | 4.2 ns max @ 4.5–5.5 V - supports >100 MHz toggle rates in critical timing paths. |
| Input Leakage Current | ±5.0 µA max @ 3.6 V - ensures stable logic states with high-impedance pull-ups/downs. |
Pinout & Package
MC74LCX00D is packaged in a 14-pin SOIC (Small Outline Integrated Circuit) per case 751A, with 1.27 mm pitch, gull-wing leads, and Pb-free (RoHS-compliant) finish. Dimensions: 8.55–8.75 mm × 3.80–4.00 mm × 1.35–1.75 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | A₀, A₁, A₂, A₃ | NAND gate input A for each of four gates - must be tied to defined logic level if unused. |
| 2, 5, 12, 14 | B₀, B₁, B₂, B₃ | NAND gate input B for each of four gates - floating inputs cause excessive ICC and noise susceptibility. |
| 3, 6, 11, 8 | O₀, O₁, O₂, O₃ | Active-low NAND outputs - capable of sinking or sourcing up to 24 mA at 3.0 V. |
| 7 | GND | Digital ground reference - requires low-inductance connection to system ground plane. |
| 14 | VCC | Primary power supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V-tolerant inputs | Enables direct interface between 3.3 V/2.5 V logic domains and legacy 5 V controllers without external translators. |
| 24 mA balanced output drive | Supports fan-out of ≥10 LVTTL loads or driving 50 pF capacitive loads with <5.5 ns propagation delay at 3.3 V. |
| AEC-Q100 qualified | Validated for automotive applications including engine control modules and body electronics requiring PPAP compliance. |
| Ultra-low quiescent current | 10 µA max ICC reduces total system standby power - critical for always-on wake-up logic in infotainment and ADAS subsystems. |
| Latchup immunity >100 mA | Guarantees robustness against transient overvoltage events in noisy automotive electrical environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC00APWR | Same 14-pin TSSOP package; lower max VCC (3.6 V); no 5 V-tolerant inputs - requires external clamping for 5 V interfaces. | Not suitable for direct 5 V input interfacing; limited to 3.3 V-only systems. | Select only when system operates exclusively at ≤3.6 V and no 5 V legacy integration is needed. |
| 74AHC00PW,118 | Higher VCC range (2–5.5 V); 5 V-tolerant inputs; but higher ICC (100 µA typical) and no AEC-Q100 qualification. | Lacks automotive qualification; less suitable for safety-critical vehicle subsystems. | Prefer for cost-sensitive industrial or consumer designs where AEC-Q100 is not mandated. |
Compared with SN74LVC00APWR and 74AHC00PW,118, the MC74LCX00D uniquely combines 5 V-tolerant inputs, AEC-Q100 qualification, and ultra-low 10 µA ICC - making it the only option among the three qualified for automotive powertrain-adjacent control logic.

FAQ
What is the maximum supply voltage for MC74LCX00D?
The MC74LCX00D supports a DC supply voltage (VCC) range of −0.5 V to +6.5 V absolute maximum, with recommended operation from 1.65 V to 5.5 V. Exceeding 5.5 V during normal operation risks parametric degradation, though the 6.5 V absolute max allows brief transients. Always refer to the Recommended Operating Conditions table in the official datasheet for design margin guidance.
Does MC74LCX00D have built-in bus-hold or Schmitt-trigger inputs?
No, the MC74LCX00D does not include bus-hold or Schmitt-trigger functionality. Its inputs are standard CMOS with TTL-compatible thresholds and require explicit termination - unused inputs must be tied to VCC or GND to prevent floating states that increase ICC and induce noise susceptibility. This is explicitly stated in the datasheet's "Functional Operation" note.
Is MC74LCX00D pin-compatible with standard 74LS00 or 74HC00 devices?
The MC74LCX00D uses the same 14-pin SOIC footprint and pinout as industry-standard quad 2-input NAND gates (e.g., 74LS00, 74HC00), with identical A/B inputs and O outputs per gate. However, its electrical behavior differs: it features 5 V-tolerant inputs and lower VCC range - so while PCB layout is compatible, system-level voltage domain validation is required before drop-in replacement.
What is the output drive capability of MC74LCX00D at 2.5 V supply?
At VCC = 2.5 V, the MC74LCX00D delivers ±16 mA output drive (per the DC Electrical Characteristics table), with VOL ≤ 0.4 V at IOL = 16 mA and VOH ≥ 2.2 V at IOH = −16 mA. This supports reliable interfacing with 2.5 V LVTTL and LVCMOS loads while maintaining noise margins above 0.7 V.
How does the −Q suffix in MC74LCX00DTR2G−Q* affect the device?
The −Q suffix denotes an automotive-grade variant of the MC74LCX00DTR2G, fully qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), with PPAP documentation support and controlled manufacturing site/process changes. It is not a functional variant - electrical specs match the base MC74LCX00D, but lot traceability, burn-in testing, and change control meet automotive OEM requirements.
