Product details
Overview
74HCT30D-Q100J from Nexperia is an automotive-grade 8-input NAND gate in SO14 package, operating from 4.5 V to 5.5 V supply, with TTL-compatible inputs, propagation delay of 16 ns (typ) at VCC = 4.5 V and CL = 50 pF, and qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C) for engine control unit signal conditioning.
For engineers reviewing the 74HCT30D-Q100J datasheet, 74HCT30D-Q100J pinout, 74HCT30D-Q100J application, or 74HCT30D-Q100J equivalent, this page delivers verified pin functions, automotive temperature range compliance, TTL-level input thresholds, output drive capability (±4.0 mA), and SO14 mechanical dimensions - all critical for board-level integration in safety-relevant logic networks.
Technical Context
This device implements a single 8-input NAND function with CMOS output stage and TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V TTL logic families without level shifting. Input clamp diodes allow safe operation with input voltages exceeding VCC when used with current-limiting resistors.
It features low static power consumption (ICC ≤ 40 μA at −40 °C to +125 °C), high noise immunity (typical VIH–VIL margin > 1.2 V), and latch-up immunity exceeding 100 mA per JESD78 Class II Level B - essential for under-hood automotive environments subject to EMI and supply transients.

Pinout & Package
SO14 plastic small outline package (SOT108-1), 14-lead, body width 3.9 mm, lead pitch 1.27 mm, compliant with JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data input | First NAND operand; accepts TTL-level signals up to VCC + 0.5 V via internal clamp diode |
| 2 (B) | Data input | Second NAND operand; electrically identical to Pin 1, fully interchangeable in layout |
| 3 (C) | Data input | Third NAND operand; shares same input capacitance (3.5 pF) and leakage (<±1 μA) |
| 4 (D) | Data input | Fourth NAND operand; no internal pull-up/pull-down; requires external termination if floating |
| 5 (E) | Data input | Fifth NAND operand; referenced to GND; VIH/VIL thresholds stable over full temperature range |
| 6 (F) | Data input | Sixth NAND operand; compatible with 5 V microcontroller GPIOs without series resistor |
| 7 (GND) | Ground reference | 0 V return path for all inputs/outputs; must be low-impedance connection to minimize ground bounce |
| 8 (Y) | Data output | NAND result; CMOS push-pull structure enables rail-to-rail swing and fan-out ≥10 |
| 9, 10, 13 (n.c.) | Not connected | No internal bond wire; PCB pads may be omitted or grounded for thermal relief - no electrical effect |
| 11 (G) | Data input | Seventh NAND operand; identical timing and voltage specs as Pins 1–6 |
| 12 (H) | Data input | Eighth NAND operand; final input required to assert low output; all eight must be high for Y = low |
| 14 (VCC) | Supply voltage | +4.5 V to +5.5 V power rail; decoupling capacitor (100 nF) required within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with life test data, failure mode analysis, and stress screening per automotive reliability standard |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V supply - eliminates need for external level translators when interfacing with legacy 5 V controllers |
| Input clamp diodes | Enable safe interface to voltages up to VCC + 0.5 V using series current-limiting resistors - critical for sensor signal conditioning with overvoltage transients |
| Low dynamic power dissipation | CPD = 15 pF - limits switching power to <1.7 mW at 1 MHz toggle rate and 5 V supply, reducing thermal load in dense PCB layouts |
| High noise immunity | Typical noise margin >1.2 V across full temperature range - suppresses false triggering from coupled ignition or alternator ripple in vehicle harnesses |
Applications
| Engine Control Unit Logic | Body Control Module Signal Gating |
|---|---|
Use Scenario: Combining eight discrete sensor fault flags (e.g., O2 heater, cam position, crank position, knock, MAP, IAT, ECT, throttle) into a single aggregated "engine fault" signal for dashboard warning activation. IC Role / Device Role / Timing Role: 8-input combinatorial logic gate performing real-time fault aggregation with sub-20 ns propagation delay - no clock or state retention required. Use Value: Reduces MCU GPIO count by 7 pins while maintaining deterministic, glitch-free fault detection without software polling overhead. |
Use Scenario: Enabling door lock actuation only when all safety conditions are met: ignition OFF, driver door closed, key fob detected, brake pedal released, gear in PARK, hood closed, trunk closed, and hazard lights OFF. IC Role / Device Role / Timing Role: Single-chip 8-input NAND acting as hardware interlock - output goes low only when all eight conditions are true, directly driving a lock solenoid enable line. Use Value: Provides fail-safe hardware-enforced access control independent of firmware execution, eliminating single-point software failure risk. |
| Transmission Control Safety Logic | ADAS Camera Power Sequencing |
Use Scenario: Validating eight transmission sensor inputs (TSS, OSS, TFP, SLU, SLT, SLN, TCC, PRNDL) before permitting torque request acceptance from the engine ECU. IC Role / Device Role / Timing Role: Combinatorial validation gate feeding a safety monitor circuit - output remains high unless all sensors report valid status simultaneously. Use Value: Enables hardware-level sensor fusion check prior to actuator command issuance, satisfying ISO 26262 ASIL-B diagnostic coverage requirements. |
Use Scenario: Generating a master enable signal for a surround-view camera module only when eight subsystems are ready: main SoC powered, ISP initialized, lens focus calibrated, IR LED driver stable, image buffer allocated, CAN bus synchronized, GPS lock acquired, and thermal sensor below threshold. IC Role / Device Role / Timing Role: Synchronous readiness aggregator - output transitions low only after all eight readiness signals stabilize, synchronizing power-on sequence. Use Value: Prevents partial initialization and image corruption by ensuring all camera subsystems meet startup prerequisites before enabling video pipeline. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT30PW-Q100 | TSSOP14 package (SOT402-1), 4.4 mm body width, 0.65 mm pitch - 35 % smaller footprint than SO14 | Preferred for space-constrained ADAS ECUs where PCB area is premium; thermal resistance higher (7.3 mW/K derating above 81 °C) | Select when board density outweighs thermal margin; verify reflow profile compatibility with thinner leads. |
| SN74HCT30QPWRQ1 | Texas Instruments variant; identical logic function and AEC-Q100 Grade 1 rating but different VIL/VIH tolerances (VIH = 2.0 V min, VIL = 0.8 V max same) and slightly higher ICC (≤60 μA) | Drop-in replacement in TI-based designs; differs in ESD rating (HBM > 4000 V) and package marking format | Choose when sourcing from TI-aligned supply chain or requiring higher HBM ESD margin; verify pinout match (identical SO14). |
Compared with 74HCT30PW-Q100, the 74HCT30D-Q100J offers lower thermal resistance and easier hand-soldering due to SO14 lead geometry; versus SN74HCT30QPWRQ1, it provides tighter ICC specification and Nexperia's documented automotive qualification traceability - critical for OEM PPAP submissions.

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, enabled by internal clamp diodes. Exceeding this requires external current limiting per datasheet Section 7 (IIK ≤ ±20 mA). Operation above VCC without current limiting risks permanent damage per IEC 60134 limiting values.
Can unused inputs be left floating?
No. All eight inputs must be actively driven HIGH or LOW; floating inputs cause increased ICC, unpredictable output states, and potential oscillation due to CMOS input stage metastability. Tie unused inputs to VCC or GND via ≤1 kΩ resistor to ensure defined logic level and minimize power waste.
Is this device suitable for 3.3 V logic systems?
No. The 74HCT30D-Q100J is specified only for 4.5 V to 5.5 V supply and TTL-level inputs. For 3.3 V systems, use the 74HC30D-Q100 (CMOS-input version) or a level-shifting solution - applying 3.3 V inputs to this part violates VIH minimum (2.0 V) and risks unreliable HIGH detection.
How does the n.c. pin configuration affect PCB layout?
Pins 9, 10, and 13 are unconnected die pads with no internal bonding. They may be omitted from copper pours or grounded for thermal relief; neither improves nor degrades electrical performance. Avoid routing signal traces beneath these pins to prevent unintended coupling in high-speed layouts.
