Product details
Overview
74LVC32AD from Nexperia is a quad 2-input OR gate logic IC in SO14 (SOT108-1) package, operating from 1.2 V to 3.6 V supply, with overvoltage-tolerant inputs up to 5.5 V and Schmitt-trigger inputs for noise immunity. It enables level translation between 3.3 V and 5 V systems and supports industrial temperature range (−40 °C to +125 °C). Used in bus arbitration, control signal combining, and mixed-voltage interface logic.
For engineers reviewing the 74LVC32AD datasheet, 74LVC32AD pinout, 74LVC32AD application, or 74LVC32AD equivalent, this page delivers verified functional role, SO14 pin mapping, propagation delay (1.0–5.0 ns), input/output voltage thresholds, and direct alternatives for logic-level translation and OR-gate consolidation tasks.
Technical Context
The 74LVC32AD implements four independent CMOS OR gates with Schmitt-trigger inputs, enabling robust operation with slow-rising or noisy signals. Its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC (1.2–3.6 V), making it suitable for bidirectional voltage translation without external components.
It complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across supply ranges, and features ESD protection exceeding 2000 V HBM and 1000 V CDM - critical for board-level reliability in industrial control and instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.2 V to 3.6 V - supports low-power portable and mixed-supply systems; not 5 V tolerant on VCC. |
| Input Voltage Range | −0.5 V to 5.5 V - enables safe interfacing with 5 V TTL outputs while powered from 1.8 V or 3.3 V rails. |
| Propagation Delay | 1.0 ns (min) to 5.0 ns (max) at VCC = 3.0–3.6 V - ensures timing predictability in high-speed control paths. |
| Output Drive | ±24 mA per output - sufficient to drive multiple LVC/LVT inputs or small capacitive loads (<30 pF). |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLCs, and extended-temperature embedded controllers. |
| Power Dissipation | 500 mW (SO14, Tamb ≤ 100 °C) - derates linearly above 100 °C (10.1 mW/K); enables thermal-aware layout in dense PCBs. |
| Input Hysteresis | Typical ΔVIH/VIL ≈ 0.3–0.5 V - inherent Schmitt-trigger action suppresses chatter on slow or noisy control lines. |
Pinout & Package
74LVC32AD is housed in a plastic small outline package (SO14, SOT108-1) with 14 leads and 3.9 mm body width. The package is RoHS-compliant, surface-mountable, and rated for reflow per JEDEC J-STD-020.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input of each OR gate - accepts 0–5.5 V; Schmitt-triggered for noise margin. |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input of each OR gate - identical electrical behavior to A inputs. |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | OR output per gate - CMOS push-pull, rail-to-rail swing, ±24 mA drive capability. |
| 7 | GND | Ground reference (0 V) - must be low-impedance connection for noise suppression and stable logic thresholds. |
| 14 | VCC | Positive supply (1.2–3.6 V) - decoupling capacitor (100 nF) recommended within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | 5.5 V absolute max input voltage - eliminates need for external level-shifting resistors when interfacing with legacy 5 V logic. |
| Schmitt-trigger inputs | Hysteresis ≥ 300 mV typical - rejects noise on reset, enable, or interrupt lines without external RC filtering. |
| Wide VCC range | 1.2 V to 3.6 V operation - supports battery-powered IoT nodes (1.8 V), FPGA I/O banks (2.5 V), and microcontroller peripherals (3.3 V). |
| JEDEC compliance | JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), JESD8-C/JESD36 (2.7–3.6 V) - ensures interoperability across voltage-tiered logic families. |
| High ESD robustness | ≥2000 V HBM, ≥1000 V CDM - reduces field failure risk during handling and system integration in unshielded industrial environments. |
Applications
| Industrial Control Logic | Microcontroller GPIO Expansion |
|---|---|
|
Use Scenario: Combining multiple sensor fault flags into a single system-alert line in a PLC backplane. IC Role / Device Role / Timing Role: Quad OR gate performing wired-OR aggregation of four independent digital fault signals with no propagation skew between channels. Use Value: Reduces BOM count vs. discrete diode-OR; eliminates timing uncertainty from external pull-ups; maintains full 1.2–3.6 V compatibility across sensor modules. |
Use Scenario: Extending limited MCU GPIOs to drive multiple enable lines for peripheral ICs (e.g., ADCs, DACs, sensors) sharing common power domains. IC Role / Device Role / Timing Role: Logic-level translator and signal combiner - accepts 5 V enable signals from legacy peripherals and drives 3.3 V enable inputs on modern ICs. Use Value: Enables direct 5 V → 3.3 V translation without external MOSFETs or resistive dividers; Schmitt inputs tolerate slow-rising enable pulses from mechanical switches. |
| Bus Arbitration Interface | Mixed-Voltage System Monitoring |
|
Use Scenario: Resolving bus grant requests from four independent masters in an embedded multi-processor subsystem. IC Role / Device Role / Timing Role: Priority-agnostic OR gate generating a shared BUS_BUSY signal - all four request inputs feed one gate per master, outputs OR'd to central arbiter. Use Value: Guarantees sub-5 ns worst-case response time across temperature; eliminates metastability risk from asynchronous request edges due to Schmitt-trigger input conditioning. |
Use Scenario: Monitoring health status of three 5 V power rails and one 3.3 V rail in a telecom line card, asserting a single POWER_OK signal if any rail fails. IC Role / Device Role / Timing Role: Voltage-agnostic fault detector - inputs directly connected to rail monitors (open-drain or push-pull), outputs combined into active-low alarm. Use Value: Eliminates need for separate level shifters per rail; overvoltage tolerance allows direct connection to 5 V supervisor outputs; operates reliably at −40 °C for outdoor base stations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC32APWR | TSSOP14 (SOT402-1) package; identical electrical specs; 4.4 mm body width; 7.3 mW/K thermal derating above 81 °C. | Better thermal performance in high-density layouts; smaller footprint than SO14 but requires finer pitch soldering. | Select when board space is constrained and reflow profile supports 0.65 mm pitch; verify thermal margin under continuous 24 mA load. |
| 74LVC32ABQ | DHVQFN14 (SOT762-1); 2.5 × 3 × 0.85 mm; exposed thermal pad; 9.6 mW/K derating above 98 °C; no leads. | Superior thermal resistance (θJA ≈ 65 K/W vs. SO14's ~120 K/W); requires PCB thermal via array under pad. | Choose for thermally demanding applications (e.g., sealed enclosures >85 °C ambient); validate solder paste volume and reflow ramp for QFN. |
Compared with SN74LVC32APWR and 74LVC32ABQ, the 74LVC32AD offers the broadest manufacturing familiarity and easiest hand-soldering/inspection in SO14, while maintaining identical logic functionality and voltage translation capability - ideal for prototyping, low-volume industrial builds, and legacy-compatible upgrades.

FAQ
Can 74LVC32AD operate with a 5 V supply?
No. The 74LVC32AD has a maximum VCC rating of 3.6 V. Applying 5 V to VCC will cause permanent damage. However, its inputs tolerate up to 5.5 V regardless of VCC - enabling safe connection to 5 V signal sources while powered from 1.8 V or 3.3 V rails.
Does 74LVC32AD require external pull-up or pull-down resistors?
No. All inputs feature Schmitt-trigger action with built-in hysteresis, eliminating the need for external resistors to prevent floating-state oscillation. Outputs are push-pull CMOS and do not require pull-ups for standard logic interfacing.
What is the maximum capacitive load the 74LVC32AD can drive?
The device is characterized up to 50 pF load capacitance (per Table 8 test conditions). Driving >50 pF increases propagation delay nonlinearly and may cause overshoot/ringing; for >100 pF loads, add a series resistor (22–47 Ω) near the output to dampen reflections.
Is 74LVC32AD suitable for automotive applications?
No. This part is not AEC-Q100 qualified and lacks automotive-grade screening, qualification testing, or guaranteed PPAP documentation. Nexperia explicitly states non-automotive qualification in its legal disclaimers; use only in industrial, computing, or communications equipment.
