Product details
Overview
74HC32BQ-Q100 from Nexperia is an automotive-qualified quad 2-input OR gate in DHVQFN14 package, operating from 2.0 V to 6.0 V supply, with propagation delay as low as 6 ns at VCC = 6.0 V and CL = 50 pF, CMOS-level inputs, and AEC-Q100 Grade 1 qualification for under-hood control logic.
For engineers reviewing the 74HC32BQ-Q100 datasheet, 74HC32BQ-Q100 pinout, 74HC32BQ-Q100 application, or 74HC32BQ-Q100 equivalent, this device supports high-noise-immunity combinational logic in automotive body control modules, powertrain interface circuits, and ADAS sensor signal conditioning where rail-to-rail input compatibility and thermal-enhanced packaging are required.
Technical Context
This IC implements four independent 2-input OR gates using standard CMOS process technology, with symmetrical output impedance and balanced tPHL/tPLH propagation delays across all channels. Input clamp diodes enable safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
It operates over -40 °C to +125 °C ambient temperature, complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), and features ESD protection exceeding 2000 V HBM and 1000 V CDM - critical for automotive assembly and field reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Four independent 2-input OR gates (A + B → Y) |
| Supply Voltage Range | 2.0 V to 6.0 V - supports wide-battery automotive systems including start-stop operation |
| Propagation Delay (tpd) | 6 ns typical at VCC = 6.0 V, CL = 50 pF - enables timing-critical combinatorial logic in <10 ns windows |
| Input Threshold (VIH/VIL) | CMOS-level: VIH = 4.2 V, VIL = 1.8 V at VCC = 6.0 V - ensures noise margin >1.2 V in 5 V systems |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive 10 LSTTL loads or 50 pF capacitive bus |
| Quiescent ICC | 2.0 μA typical at VCC = 6.0 V - enables ultra-low static power in always-on vehicle subsystems |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for engine compartment and transmission control unit deployment |
Pinout & Package
DHVQFN14 (SOT762-1) package: 2.5 × 3.0 × 0.85 mm body, no leads, exposed thermal pad (non-electrical unless connected to GND), side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 4A, 9A, 12A | Input A of Gate 1–4 | CMOS-compatible digital input; clamped to VCC/GND for overvoltage tolerance |
| 2B, 5B, 10B, 13B | Input B of Gate 1–4 | Second OR operand per gate; identical electrical characteristics to A inputs |
| 3Y, 6Y, 8Y, 11Y | Output Y of Gate 1–4 | Push-pull CMOS output; symmetrical rise/fall times and drive strength |
| 7 | GND | Ground reference (0 V); mandatory connection for bias and noise control |
| 14 | VCC | Primary supply rail; decoupling capacitor placement adjacent to this pin is critical for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 certified - validated for 15-year automotive service life under thermal cycling and humidity stress |
| Thermal-enhanced packaging | DHVQFN14 with side-wettable flanks - improves heat dissipation vs. SO14/TSSOP and enables automated optical solder inspection |
| Input overvoltage tolerance | Clamp diodes allow safe interface to signals up to VCC + 0.5 V using external current-limiting resistors |
| Noise immunity | High noise margin (>1.2 V at 5 V) and 100 mA latch-up immunity per JESD78 Class II Level B |
| Low dynamic power | CPD = 16 pF - minimizes switching power in high-frequency control logic (e.g., PWM state decoding) |
Applications
| Body Control Module (BCM) | Powertrain Control Interface |

IC Role / Device Role / Timing Role: Combinational OR logic aggregator with sub-10 ns propagation ensuring deterministic response under CAN/LIN interrupt latency constraints. Use Value: Eliminates need for microcontroller GPIO expansion while maintaining fail-safe behavior - any active input asserts output immediately without software overhead. |
Use Scenario: Validating dual-redundant throttle position sensor outputs before feeding to engine ECU safety monitor. IC Role / Device Role / Timing Role: Hardware-level fault detection gate that triggers diagnostic flag if either sensor reports valid signal during idle condition. Use Value: Provides SIL-2 compliant hardware voting path independent of firmware, meeting ISO 26262 ASIL-B requirements for sensor redundancy validation. |
| ADAS Sensor Signal Conditioning | Infotainment System Power Sequencing |
|

IC Role / Device Role / Timing Role: Low-latency edge-sensitive combiner enabling immediate wake-up of processing core upon first sensor assertion. Use Value: Reduces system wake latency by >50% vs. polling-based software detection, extending battery life in parked ADAS monitoring mode. |
Use Scenario: Enabling display backlight driver only when both ignition ON signal and head unit power-good status are asserted. IC Role / Device Role / Timing Role: Power sequencing enabler that prevents inrush current conflicts between subsystems during cold start. Use Value: Avoids brown-out events on shared 5 V rail by ensuring strict activation order - eliminates display flicker and firmware reset loops. |
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 |
|---|---|---|---|
| 74HCT32BQ-Q100 | TTL-compatible inputs (VIH = 2.0 V min), slightly higher tpd (11 ns typ at 4.5 V) | Better interoperability with legacy 5 V TTL logic; lower noise margin in mixed-voltage systems | Select when interfacing directly to older microcontrollers or discrete transistor logic without level shifters |
| SN74LVC32APWREP | 3.3 V only (1.65–3.6 V), smaller TSSOP14 package, lower CPD (12 pF), non-automotive grade | Limited to cabin electronics; not qualified for under-hood thermal or lifetime requirements | Use only in non-safety-critical infotainment or telematics modules where cost and size outweigh AEC-Q100 needs |
Compared with 74HC32BQ-Q100, the 74HCT32BQ-Q100 offers easier integration with 5 V TTL sources but sacrifices noise margin, while SN74LVC32APWREP reduces board space and dynamic power at the expense of automotive qualification and voltage flexibility.

FAQ
What is the maximum allowable supply voltage for continuous operation?
The absolute maximum supply voltage is +7.0 V, but continuous operation must remain within the recommended range of 2.0 V to 6.0 V. Exceeding 6.0 V risks accelerated parametric drift and reduced long-term reliability, even if within absolute limits - design margins require adherence to 6.0 V max for 15-year automotive service life.
Can the exposed thermal pad be left unconnected?
Yes - the exposed pad (terminal 1 index area) has no electrical requirement and may remain floating. If soldered, it must be either left electrically isolated or connected to GND; connecting to any other net violates the datasheet's thermal and ESD design intent and compromises latch-up immunity.
How does input clamping affect interfacing with 12 V sensor signals?
Clamp diodes allow safe interface to signals up to VCC + 0.5 V only. For true 12 V sensor signals, an external current-limiting resistor (e.g., 10 kΩ) is mandatory to restrict IIK to ≤±20 mA, preventing damage. Direct 12 V connection without limiting will exceed absolute maximum ratings.
Is this device compatible with 3.3 V microcontroller I/O?
Yes - at VCC = 3.3 V, VIH = 2.31 V (70% of VCC) and VIL = 0.99 V (30% of VCC) provide 0.81 V noise margin, fully compatible with standard 3.3 V CMOS outputs. Output VOH ≈ 3.15 V and VOL ≈ 0.15 V at IO = ±4 mA meet 3.3 V logic thresholds with margin.
