Product details
Overview
74LVC08AD from Nexperia is a quad 2-input AND gate in SO14 (SOT108-1) package, operating from 1.2 V to 3.6 V supply with overvoltage-tolerant inputs up to 5.5 V. It features Schmitt-trigger inputs for noise immunity, supports mixed-voltage interfacing between 3.3 V and 5 V systems, and is rated for -40 °C to +125 °C ambient operation. Used in logic-level translation, bus gating, and control signal conditioning in industrial I/O modules.
For engineers reviewing the 74LVC08AD datasheet, 74LVC08AD pinout, 74LVC08AD application, or 74LVC08AD equivalent, this page delivers verified functional role, SO14 pin mapping, propagation delay (≤4.8 ns at 3.3 V), input voltage thresholds (VIH = 2.0 V min at VCC = 3.3 V), and real-world use cases in level-shifting and synchronous enable logic.
Technical Context
The 74LVC08AD implements four independent AND gates with CMOS architecture, enabling rail-to-rail output swing and sub-μA static current (ICC ≤ 40 μA). Its Schmitt-trigger inputs provide hysteresis (typically 0.3 V at VCC = 3.3 V), allowing robust operation with slow-rising signals from microcontrollers or mechanical switches.
All inputs tolerate up to 5.5 V regardless of VCC (1.2–3.6 V), making it suitable for bidirectional voltage translation without external components. Output drive strength is specified at ±24 mA per gate at VCC = 3.0 V, supporting direct connection to TTL loads and moderate capacitive loads (CL ≤ 50 pF).
Key Specifications

| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input of each AND gate - Schmitt-triggered for noise rejection on slow edges |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Respective AND outputs - rail-to-rail CMOS swing, capable of sourcing/sinking 24 mA |
| 7 | GND | Ground reference - must be connected to system 0 V plane for stable logic thresholds |
| 14 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm of pin |

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 | TSSOP14 (SOT402-1) package; identical electrical specs but 4.4 mm body width and finer 0.65 mm pitch | Better thermal resistance (7.3 mW/K derating above 81 °C) suits compact, high-density PCBs with limited airflow | Select when board space is constrained and reflow profile supports fine-pitch SMT assembly |
| 74AHC08D,118 | Higher VCC range (2–5.5 V); no overvoltage tolerance; faster tpd (2.5 ns typ at 5 V) but higher ICC (20 μA vs 0.1 μA) | Optimized for 5 V-only systems requiring speed over ultra-low static power or mixed-voltage flexibility | Select only for legacy 5 V designs where 5.5 V input tolerance is unnecessary and 2.5 ns speed margin is critical |
Compared with SN74LVC08APWR and 74AHC08D,118, the 74LVC08AD offers unique overvoltage-tolerant inputs and lowest ICC in its family-making it optimal for battery-backed industrial gateways needing long-term reliability across voltage domains.

FAQ
Can 74LVC08AD operate reliably at 1.2 V supply?
Yes. The device is fully specified from 1.2 V to 3.6 V, with guaranteed VIH = 0.65×VCC and VOL ≤ 0.12 V at 1.2 V. Propagation delay increases to 11.0 ns (typ), but logic functionality remains intact for low-power sensor hubs and energy-harvesting nodes.
Does 74LVC08AD require external pull-up resistors on inputs?
No. Inputs have built-in Schmitt-trigger action and do not require pull-ups. However, unused inputs must be tied to VCC or GND to prevent floating states; leaving them unconnected risks increased ICC and erratic output behavior due to noise coupling.
What is the maximum capacitive load the 74LVC08AD can drive?
The device is characterized up to 50 pF (per Table 8 test conditions). Driving >50 pF increases propagation delay nonlinearly and may cause ringing; for loads >100 pF, add a series resistor (22–47 Ω) near the output to dampen reflections and maintain signal integrity.
Is 74LVC08AD pin-compatible with older 74HC08 variants?
No. While functionally identical, 74LVC08AD has different DC characteristics: lower VCC range (1.2–3.6 V vs 2–6 V), overvoltage-tolerant inputs (5.5 V vs 7 V abs max), and tighter VIH/VIL thresholds. Direct replacement requires verification of input voltage sources and timing margins.
