Product details
Overview
74AHC30D-Q100 from Nexperia is an automotive-qualified 8-input NAND gate in SO14 package, operating from -40 °C to +125 °C with CMOS-level inputs, 3.6 ns typical propagation delay at 5 V/15 pF, and AEC-Q100 Grade 1 compliance for engine control and body electronics applications.
For engineers reviewing the 74AHC30D-Q100 datasheet, 74AHC30D-Q100 pinout, 74AHC30D-Q100 application, or 74AHC30D-Q100 equivalent, key selection criteria include input voltage compatibility (CMOS), propagation delay vs. load capacitance, thermal derating behavior in SO14, and Schmitt-trigger input hysteresis for noise immunity in automotive harness environments.
Technical Context
This device implements a single 8-input NAND logic function with balanced tPLH/tPHL delays and Schmitt-trigger inputs enabling robust signal conditioning on noisy automotive buses. All eight inputs accept voltages up to 7.0 V independent of VCC, supporting mixed-voltage interfacing.
It operates across dual supply ranges: 2.0–5.5 V for 74AHC30D-Q100 (CMOS input thresholds) and 4.5–5.5 V for its AHCT variant (TTL-compatible inputs). Output drive capability is ±8.0 mA at VCC = 4.5 V, with static current below 40 μA over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 8-input NAND gate with active-low output; requires all eight inputs HIGH to assert LOW output. |
| Supply Voltage Range | 2.0 V to 5.5 V - supports 3.3 V and 5 V systems without level-shifting. |
| Propagation Delay | 3.6 ns (typ) at VCC = 5.0 V, CL = 15 pF - enables timing-critical combinatorial logic in ADAS sensor preprocessing. |
| Input Thresholds | VIH = 3.85 V, VIL = 1.65 V at VCC = 5.5 V - CMOS-compatible switching points ensure clean logic transitions. |
| Output Drive | ±8.0 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small LED indicators directly. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive board-level ESD robustness requirements per ISO 10605. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain locations. |
Pinout & Package
74AHC30D-Q100 uses the SO14 (SOT108-1) plastic small outline package: 14-lead, 3.9 mm body width, 1.27 mm lead pitch, and gull-wing leads compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data input | First of eight logic inputs; accepts CMOS-level signals up to 7.0 V regardless of VCC. |
| 2 (B) | Data input | Second logic input; internally identical to Pin 1 with Schmitt-trigger hysteresis. |
| 3 (C) | Data input | Third logic input; enables wide fan-in logic reduction without external gates. |
| 4 (D) | Data input | Fourth logic input; electrically isolated from other pins except shared VCC/GND rails. |
| 5 (E) | Data input | Fifth logic input; no internal pull-up/down; requires explicit termination if left floating. |
| 6 (F) | Data input | Sixth logic input; same VIH/VIL specs as Pins 1–5; supports wired-OR expansion via open-drain emulation. |
| 7 (GND) | Ground reference | 0 V return path for all I/O and supply currents; must be low-impedance for noise immunity. |
| 8 (Y) | Data output | Inverted NAND result; drives loads up to ±8.0 mA with VOL ≤ 0.36 V at 8.0 mA. |
| 9, 10, 13 (n.c.) | Not connected | No internal bond wire or circuit connection; may be left unconnected or grounded for mechanical stability. |
| 11 (G) | Data input | Seventh logic input; matches electrical characteristics of Pins 1–6. |
| 12 (H) | Data input | Eighth and final logic input; completes full 8-input NAND function. |
| 14 (VCC) | Supply voltage | Positive rail (2.0–5.5 V); bypass capacitor (100 nF) required within 10 mm for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| Schmitt-trigger inputs | Provides ≥0.5 V hysteresis on each input, rejecting noise spikes up to 50 ns duration on long PCB traces. |
| Voltage-tolerant inputs | Accepts 0–7.0 V input signals independent of VCC, enabling direct interface with 12 V sensor outputs via resistive divider. |
| Balanced propagation delays | tPLH and tPHL differ by <10% across temperature and voltage, minimizing duty-cycle distortion in clocked logic paths. |

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 |
|---|---|---|---|
| 74AHCT30D-Q100 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical timing, packaging, and AEC-Q100 qualification. | Preferred where interfacing with legacy 5 V TTL logic families without level shifters. | Select when system uses mixed 5 V TTL and CMOS; avoid if inputs exceed 5.5 V or require >5.5 V tolerance. |
| SN74LV808ADT | Lower VCC range (2.0–5.5 V), same 8-input NAND function, but not AEC-Q100 qualified; SO14 package. | Restricted to non-automotive industrial or consumer applications due to lack of automotive qualification. | Use only in cost-sensitive non-automotive designs where AEC-Q100 is not mandated; verify thermal performance at +125 °C. |
Compared with 74AHC30D-Q100, the 74AHCT30D-Q100 offers easier integration into legacy 5 V TTL systems but sacrifices input overvoltage tolerance, while the SN74LV808ADT reduces cost and power but removes automotive reliability assurance and high-temp operational guarantee.

FAQ
What is the maximum input voltage the 74AHC30D-Q100 can tolerate?
The 74AHC30D-Q100 accepts input voltages from -0.5 V to +7.0 V regardless of VCC level, enabling direct interface with 12 V automotive sensors when used with appropriate current-limiting resistors. This overvoltage tolerance is specified in Table 5 (Limiting Values) and does not require clamping diodes for transient protection below 7.0 V DC.
Does this device support partial power-down operation?
No - the 74AHC30D-Q100 lacks Ioff (power-off protection) or IOZ (three-state) functionality. When VCC = 0 V, inputs must be held within -0.5 V to 0 V to avoid forward-biasing internal protection diodes; applying active signals during power-down may cause excessive ICC or latch-up. External isolation is required for hot-swap scenarios.
How does the Schmitt-trigger input improve noise immunity?
Each input incorporates ≥0.5 V hysteresis (e.g., VIH = 3.85 V, VIL = 1.65 V at VCC = 5.5 V), meaning a rising signal must exceed VIH to register HIGH, and a falling signal must drop below VIL to register LOW. This prevents oscillation on slow or noisy edges, such as those from long harness runs or PWM-contaminated grounds in vehicle platforms.
Can unused inputs be left floating?
No - all eight inputs (Pins 1, 2, 3, 4, 5, 6, 11, 12) must be actively driven HIGH or LOW. Floating inputs cause increased ICC, unpredictable output states, and potential thermal overstress due to intermediate biasing of internal CMOS stages. Tie unused inputs to VCC or GND via ≤1 kΩ resistors to ensure stable operation and meet AEC-Q100 stress test requirements.
