Overview
74AHCT30PW-Q100 from Nexperia is an automotive-grade 8-input NAND gate in TSSOP14 package, operating from -40 °C to +125 °C with TTL-level inputs, 3.3 ns typical propagation delay at 5 V/15 pF, and AEC-Q100 Grade 1 qualification for engine control and ADAS sensor interface logic.
For engineers reviewing the 74AHCT30PW-Q100 datasheet, 74AHCT30PW-Q100 pinout, 74AHCT30PW-Q100 application, or 74AHCT30PW-Q100 equivalent, this page delivers verified pin functions, automotive thermal specs, input voltage thresholds, output drive capability, and direct alternatives for logic-level translation and bus arbitration in safety-critical systems.
Technical Context
This device implements a single 8-input NAND function using high-speed Si-gate CMOS technology with Schmitt-trigger inputs, enabling noise-immune signal conditioning in noisy automotive environments. It accepts TTL-level inputs (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) while driving CMOS-compatible outputs.
The logic core operates with balanced propagation delays (tPLH ≈ tPHL), supports input overvoltage tolerance up to 7.0 V, and features ESD protection exceeding 2000 V HBM and 1000 V CDM - critical for under-hood module reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 8-input NAND gate with active-low output; enables compact bus enable/control logic without external gates. |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard 5 V automotive microcontroller I/O rails and ensures compatibility with legacy TTL systems. |
| Propagation Delay | 3.3 ns typical (CL = 15 pF, VCC = 5 V) - supports >100 MHz toggle rates in timing-critical combinatorial paths. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees robust interfacing with 3.3 V and 5 V TTL sources without level shifters. |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive 10 LSTTL loads or terminate short PCB traces in distributed logic networks. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for powertrain and chassis modules exposed to under-hood thermal stress. |
| ESD Rating | HBM >2000 V, CDM >1000 V - exceeds automotive ESD immunity requirements for assembly and field operation. |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, body width 4.4 mm, 0.65 mm pitch, side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data input | First of eight independent logic inputs; accepts TTL/CMOS levels and tolerates up to 7.0 V. |
| 2 (B) | Data input | Second NAND input; Schmitt-trigger action provides hysteresis against slow-rising or noisy signals. |
| 3 (C) | Data input | Third input; electrically identical to A/B; no internal pull-up/down - requires external termination if floating. |
| 4 (D) | Data input | Fourth input; shares same VIH/VIL thresholds and input leakage (<2.0 μA) across full temperature range. |
| 5 (E) | Data input | Fifth input; compatible with 3.3 V and 5 V logic families due to overvoltage-tolerant input structure. |
| 6 (F) | Data input | Sixth input; all eight inputs exhibit matched propagation delay and identical DC characteristics. |
| 7 (GND) | Ground reference | 0 V return path for supply and signals; must be low-impedance to maintain noise margin and timing integrity. |
| 8 (Y) | Data output | Inverted NAND result; rail-to-rail swing (VOL = 0.36 V max, VOH = 3.94 V min at 8 mA load). |
| 9,10,13 (n.c.) | Not connected | No internal connection; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress. |
| 11 (G) | Data input | Seventh input; pin position optimized for signal routing symmetry in dense automotive PCB layouts. |
| 12 (H) | Data input | Eighth and final input; completes full 8-input function; no functional distinction from other inputs. |
| 14 (VCC) | Supply voltage | +4.5 V to +5.5 V power rail; decoupling capacitor (100 nF) required within 5 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from -40 °C to +125 °C ambient, meeting automotive powertrain and ADAS reliability requirements. |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply - enables direct interface with legacy microcontrollers, sensors, and discrete logic without level-shifting circuitry. |
| Schmitt-trigger inputs | Provides 0.4–0.6 V hysteresis per input - suppresses chatter on slow or noisy control lines such as ignition feedback or switch debounce paths. |
| Overvoltage-tolerant inputs | Withstands up to 7.0 V regardless of VCC state - protects against load-dump transients and mixed-voltage board-level faults. |
| Side-wettable flanks (TSSOP) | Enables automated optical inspection of solder joints on bottom terminals - critical for zero-defect manufacturing in automotive SMT lines. |
Applications
| Engine Control Unit (ECU) Enable Logic | ADAS Camera Sensor Interface |
|---|---|
|
Use Scenario: Enabling/disabling CAN transceiver power based on multiple status flags (crank signal, oil pressure, coolant temp). IC Role / Device Role / Timing Role: 8-input NAND acts as a hardware AND-NOT arbiter - all eight conditions must be HIGH to assert active-low enable. Use Value: Eliminates software polling latency and firmware dependency; ensures deterministic sub-10 ns response to fault conditions. |
Use Scenario: Validating synchronized frame start pulses from dual camera modules before triggering image capture. IC Role / Device Role / Timing Role: Combines eight asynchronous sync signals into one validated strobe using NAND logic with Schmitt-trigger noise rejection. Use Value: Prevents corrupted frames caused by EMI-induced glitches on long flex cable runs between cameras and SoC. |
| Electric Power Steering (EPS) Fault Monitor | Body Control Module (BCM) Door Lock Arbitration |
|
Use Scenario: Aggregating eight independent torque sensor, motor phase, and current monitor fault flags into a single system fail-safe output. IC Role / Device Role / Timing Role: Hardware-level fault consolidation node - asserts low-going FAIL signal only when all inputs indicate nominal operation. Use Value: Meets ISO 26262 ASIL-B diagnostic coverage requirements via deterministic combinational logic, not software. |
Use Scenario: Resolving simultaneous lock/unlock requests from key fob, door handle sensor, and remote app to prevent conflicting actuator commands. IC Role / Device Role / Timing Role: Priority encoder pre-logic stage - NAND output feeds priority encoder that resolves request hierarchy in fixed hardware latency. Use Value: Guarantees consistent mechanical behavior regardless of request timing skew; avoids relay chattering or motor stall. |
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 |
|---|---|---|---|
| 74AHC30PW-Q100 | CMOS-level inputs (VIH = 3.85 V min at 5.5 V); lower ICC (2 μA typ vs 20 μA typ for AHCT); identical pinout and package. | Requires 3.3 V or higher logic sources; unsuitable for direct 5 V TTL interface without level shifting. | Select when interfacing exclusively with CMOS microcontrollers or FPGAs and ultra-low static power is prioritized. |
| SN74LVX30QPWRQ1 | TSSOP14, AEC-Q100 Grade 1, but LVX family: 2.0–3.6 V supply only; VIH = 1.7 V min at 3.3 V; tpd = 5.5 ns typical (5 V equiv). | Designed for 3.3 V domains only; incompatible with 5 V systems without regulators or translators. | Choose for cost-sensitive 3.3 V ADAS domain controllers where 5 V tolerance is unnecessary. |
Compared with 74AHCT30PW-Q100, the 74AHC30PW-Q100 offers lower static current but lacks TTL compatibility, while SN74LVX30QPWRQ1 reduces supply voltage range and propagation speed - making the AHCT variant optimal for mixed-voltage 5 V automotive subsystems requiring guaranteed TTL interoperability and fast timing.

FAQ
Is 74AHCT30PW-Q100 pin-compatible with standard 74-series TTL 8-input NAND gates?
Yes - it is pin-compatible with Low-power Schottky TTL (LSTTL) equivalents such as 74LS30, sharing identical TSSOP14 pinout (SOT402-1), same 1–8 input / 9–13 n.c. / 14 VCC layout, and matching logic symbol orientation. No PCB redesign is needed for drop-in replacement in existing 5 V TTL systems.
What is the maximum input voltage the device tolerates when VCC = 0 V (unpowered)?
The absolute maximum input voltage is -0.5 V to +7.0 V regardless of VCC state. This allows hot-plug operation and safe interfacing with powered subsystems while the gate's supply is off - a key requirement for modular automotive ECUs with staggered power sequencing.
Does the "n.c." marking on pins 9, 10, and 13 imply they are internally unused or electrically isolated?
Yes - pins 9, 10, and 13 are confirmed not connected internally (no bond wire, no die pad). They serve only mechanical support and thermal dissipation roles in the TSSOP14 package. PCB footprints must leave these pads unconnected to avoid unintended coupling or solder bridging.
How does the Schmitt-trigger input improve performance in automotive environments?
Schmitt-trigger action provides ~0.5 V hysteresis between rising and falling thresholds, rejecting noise spikes <0.5 V peak-to-peak on long harness-connected inputs - critical for reliable operation on crankshaft position, brake switch, or HVAC sensor lines subject to alternator ripple and ignition EMI.
