Product details
Overview
74ALVC32D-Q100 from Nexperia is a quad 2-input OR gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 1.65 V to 3.6 V. It features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and overvoltage-tolerant inputs up to 3.6 V - deployed in body control modules, infotainment power sequencing, and ADAS sensor interface logic.
For engineers reviewing the 74ALVC32D-Q100 datasheet, 74ALVC32D-Q100 pinout, 74ALVC32D-Q100 application, or 74ALVC32D-Q100 equivalent, key selection criteria include its guaranteed operation at 125 °C ambient, IOFF-enabled hot-swap capability, Schmitt-trigger input hysteresis (min 0.3 V), and compatibility with both 1.8 V and 3.3 V logic domains in mixed-voltage automotive subsystems.
Technical Context
This device implements four independent 2-input OR logic functions with Schmitt-trigger inputs on all eight inputs, providing hysteresis to reject slow-rising or noisy signals - critical in automotive harness environments where signal integrity degrades over long traces. Each gate output drives CMOS/TTL loads with VOH ≥ VCC − 0.2 V (IO = −100 μA) and VOL ≤ 0.3 V (IO = 24 mA at VCC = 3.0 V).
The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±10 μA max, enabling safe insertion/removal in live backplane or modular ECU designs. Propagation delay is specified from 1.0 ns (typ) to 3.2 ns (max) across 1.65–3.6 V supply and full temperature range, with CPD = 25 pF per gate for dynamic power estimation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR gate (4 independent gates) |
| Supply Voltage Range | 1.65 V to 3.6 V - supports 1.8 V and 3.3 V I/O domains without level shifters |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive applications |
| Propagation Delay (tpd) | 1.0 ns (min) to 3.2 ns (max) at VCC = 3.0–3.6 V - enables timing-critical combinatorial logic paths |
| IOFF Leakage | ±10 μA max at VCC = 0 V - prevents damaging backfeed during partial power-down |
| Input Hysteresis | Min 0.3 V (Schmitt-trigger action) - rejects noise on slow-rising signals from sensors/switches |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive robustness requirements |
Pinout & Package
74ALVC32D-Q100 uses SO14 (SOT108-1) package: plastic small outline, 14-lead, 3.9 mm body width, with gull-wing leads and standard pin 1 index notch.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input of each OR gate - Schmitt-triggered, tolerant to slow edges |
| 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, capable of sourcing/sinking ≥12 mA |
| 7 | GND | Ground reference (0 V) - must be connected to system ground plane |
| 14 | VCC | Positive supply rail - decoupling capacitor (100 nF) required within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient - no derating required |
| IOFF partial power-down | Outputs disabled with <±10 μA leakage when VCC = 0 V - enables hot-swap in modular ECUs |
| Schmitt-trigger inputs | Input hysteresis ≥0.3 V - eliminates chatter on mechanical switch or inductive sensor inputs |
| Overvoltage-tolerant inputs | Accepts up to 3.6 V regardless of VCC (1.65–3.6 V) - simplifies interfacing with legacy 3.3 V peripherals |
| Direct TTL interface | VIH = 2.0 V min at VCC ≥ 2.7 V - ensures reliable recognition of TTL HIGH without pull-ups |
Applications
| Body Control Module Logic | Infotainment Power Sequencing |
|---|---|
|
Use Scenario: Combining door lock status, window position, and ignition signal to enable/disable interior lighting and HVAC fan control. IC Role / Device Role / Timing Role: Combinatorial OR logic element aggregating multiple safety-critical inputs before feeding microcontroller interrupt lines. Use Value: Schmitt-trigger inputs prevent false triggers from noisy wiring harnesses; IOFF allows safe reconfiguration during ECU firmware updates without powering down entire module. |
Use Scenario: Enabling main SoC power rails only after display backlight and audio amplifier supplies stabilize. IC Role / Device Role / Timing Role: OR gate combining multiple "ready" signals from DC-DC converters to generate centralized power-good assertion. Use Value: Guaranteed 125 °C operation ensures reliability near heat-generating power stages; overvoltage-tolerant inputs accept 3.3 V ready flags even when core logic runs at 1.8 V. |
| ADAS Sensor Interface | Automotive Gateway Diagnostics |
|
Use Scenario: Detecting fault conditions across multiple radar/LiDAR sensors by OR-ing individual fault outputs into a single diagnostic alert line. IC Role / Device Role / Timing Role: Fault aggregation node - fast propagation (<3.2 ns) ensures minimal latency in safety-critical fault reporting. Use Value: Low propagation delay and high noise immunity ensure rapid, deterministic fault escalation - meeting ASIL-B timing constraints for sensor fusion systems. |
Use Scenario: Merging CAN bus error frames, LIN timeout alerts, and flash memory CRC failures into unified diagnostic trouble code (DTC) trigger. IC Role / Device Role / Timing Role: Diagnostic event combiner - operates in same voltage domain as microcontroller I/O (1.8 V or 3.3 V) without level translation. Use Value: Direct TTL compatibility and wide VCC range eliminate external level shifters, reducing BOM count and PCB area in space-constrained gateway modules. |
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 |
|---|---|---|---|
| SN74LVC32AQDRQ1 | TI part with identical AEC-Q100 Grade 1 rating, but lacks Schmitt-trigger inputs - requires external filtering for noisy sources. | Not suitable for direct replacement in switch/sensor interfaces without added RC networks. | Select only if system already includes external noise filtering and IOFF is not required. |
| 74LVC32PW-Q100 | Nexperia TSSOP14 variant (SOT402-1) - same logic, temp, and electrical specs, but different package footprint and thermal resistance. | Compatible functionally, but requires PCB redesign due to 4.4 mm body width vs. SO14's 3.9 mm. | Choose for higher board density or improved thermal performance in thermally constrained layouts. |
Compared with SN74LVC32AQDRQ1, the 74ALVC32D-Q100 provides essential Schmitt-trigger noise rejection for unconditioned automotive inputs; compared with 74LVC32PW-Q100, it offers proven manufacturability in SO14 wave-solder processes and lower assembly cost in high-volume harness-integrated modules.

FAQ
Does 74ALVC32D-Q100 support hot-swap in live-backplane automotive architectures?
Yes - its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±10 μA maximum. This prevents damage during insertion/removal in powered systems such as modular ECU carriers or diagnostic tool interfaces, satisfying ISO 16750-2 transient robustness requirements for hot-plug scenarios.
What is the minimum input rise/fall time supported without signal degradation?
The device specifies Δt/ΔV limits: 20 ns/V at VCC = 1.65–2.7 V and 10 ns/V at VCC = 2.7–3.6 V. With typical Schmitt-trigger hysteresis of 0.3 V, this supports input edges as slow as ~6 ns (at 3.3 V) while maintaining clean output transitions - sufficient for mechanical switches, potentiometers, and legacy sensor outputs.
Can 74ALVC32D-Q100 interface directly with 5 V TTL outputs?
No - inputs tolerate up to 3.6 V absolute maximum, and VIH is specified as 2.0 V min only at VCC ≥ 2.7 V. A 5 V TTL output exceeds the 3.6 V input rating and risks latch-up or accelerated wear. Use a dedicated level translator (e.g., TXS0102) or resistor-divider network with current limiting to safely interface with 5 V sources.
Is the SO14 package (SOT108-1) lead-free and RoHS-compliant?
Yes - the 74ALVC32D-Q100 in SO14 packaging conforms to RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Nexperia confirms lead-free terminations with matte tin plating, and the device carries the "Pb-free" marking per JEDEC J-STD-609, verified via XRF testing per IPC-J-STD-020.
