Product details
Overview
74HC32D-Q100 from Nexperia is an automotive-qualified quad 2-input OR gate in SO14 (SOT108-1) 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 74HC32D-Q100 datasheet, 74HC32D-Q100 pinout, 74HC32D-Q100 application, or 74HC32D-Q100 equivalent, this device serves as a robust, low-power combinational logic element in automotive body control modules, powertrain interface circuits, and infotainment system signal conditioning where TTL-compatible timing and high noise immunity are required.
Technical Context
This IC implements four independent OR gates with symmetrical output impedance and balanced propagation delays across all channels, enabling deterministic timing in synchronous logic trees. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
It operates across -40 °C to +125 °C ambient temperature, supports wide VCC range (2.0–6.0 V), and meets JEDEC JESD7A and JESD8C standards. Static input thresholds scale with VCC for 74HC variant (VIH = 0.7×VCC min), ensuring reliable logic interpretation across supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR gate - provides four independent Boolean OR operations per package |
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct integration into 3.3 V and 5 V automotive subsystems without level shifting |
| Propagation Delay (tpd) | 6 ns (typ) at VCC = 6.0 V, CL = 50 pF - ensures sub-10 ns timing for high-speed control path decisions |
| Input Threshold (VIH/VIL) | VIH ≥ 4.2 V, VIL ≤ 1.8 V at VCC = 6.0 V - guarantees noise margin >1.6 V in 5 V systems |
| Output Drive Strength | ±4.0 mA at VCC = 4.5 V - sufficient to drive 10 LSTTL loads or multiple CMOS inputs |
| Operating Temperature | -40 °C to +125 °C - qualified for engine bay and transmission control unit environments |
| AEC-Q100 Grade | Grade 1 - certified for automotive applications requiring operation up to +125 °C junction temperature |
Pinout & Package
74HC32D-Q100 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, RoHS-compliant, and rated for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 4A, 9A, 12A | Input A of Gate 1–4 | First input terminal for each of four OR gates; accepts CMOS-level signals |
| 2B, 5B, 10B, 13B | Input B of Gate 1–4 | Second input terminal for each OR gate; electrically identical to A inputs |
| 3Y, 6Y, 8Y, 11Y | Output Y of Gate 1–4 | Active-high OR result; drives downstream logic with symmetrical rise/fall times |
| 7 | GND | Ground reference (0 V); must be connected to system ground plane for noise immunity |
| 14 | VCC | Positive supply rail; decoupling capacitor (100 nF) recommended within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient, including thermal cycling and HAST reliability testing |
| Input clamp diodes | Enables safe interface to voltages > VCC using external current-limiting resistors - eliminates need for discrete protection |
| High noise immunity | Typical noise margin >1.6 V at 5 V operation due to CMOS input thresholds and hysteresis-free design |
| Low dynamic power dissipation | CPD = 16 pF - limits switching power to <1.5 mW at 1 MHz, 5 V, reducing thermal load in dense PCB layouts |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events |
Applications

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 |
|---|---|---|---|
| 74HCT32D-Q100 | TTL-compatible inputs (VIH = 2.0 V min), same SO14 package and AEC-Q100 Grade 1 rating | Required when interfacing legacy 5 V TTL logic without level shifters; higher ICC at VCC = 4.5 V (20 µA vs. 2 µA) | Select for mixed-signal systems with 5 V TTL peripherals; avoid in battery-sensitive modules due to higher static current |
| SN74LVC32APWRQ1 | 3.3 V only (1.65–3.6 V), lower VCC max, smaller TSSOP-14 package, same AEC-Q100 Grade 1 | Suitable for modern 3.3 V domains; lacks input clamp diodes and has reduced noise margin (VIH = 2.0 V) | Prefer for space-constrained ADAS ECUs; not interchangeable in 5 V or overvoltage-tolerant designs |
Compared with 74HC32D-Q100, the 74HCT32D-Q100 offers TTL input compatibility at the cost of higher static current, while SN74LVC32APWRQ1 enables miniaturization in 3.3 V systems but sacrifices overvoltage tolerance and noise margin - selection depends on supply architecture and interface voltage requirements.

FAQ
What is the maximum allowable input voltage when VCC = 5.0 V?
The absolute maximum input voltage is VCC + 0.5 V = 5.5 V, provided input clamping current remains within ±20 mA. Input clamp diodes enable safe operation above VCC when used with appropriate series current-limiting resistors - no external protection diodes needed.
Can 74HC32D-Q100 drive a 50 pF capacitive load at 10 MHz?
Yes: with CPD = 16 pF and typical VOH/VOL of 4.4 V/0.15 V at VCC = 4.5 V, dynamic power dissipation is ~3.2 mW at 10 MHz. Output rise/fall times remain <20 ns, ensuring signal integrity without overshoot or excessive ringing on properly terminated traces.
Is the SO14 package lead-free and RoHS compliant?
Yes: 74HC32D-Q100 uses a lead-free, halogen-free SO14 (SOT108-1) package fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, and qualified for standard SnPb and Pb-free reflow profiles per JEDEC J-STD-020.
How does the 74HC32D-Q100 differ from commercial-grade 74HC32D?
74HC32D-Q100 adds AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), enhanced ESD ratings (HBM >2000 V, CDM >1000 V), stricter lot traceability, and automotive-specific reliability testing (HTOL, TC, uHAST). Electrical specs are identical, but screening and documentation meet IATF 16949 requirements.
