Product details
Overview
74AHCT30D-Q100J from Nexperia is an automotive-grade 8-input NAND gate in SO14 (SOT108-1) package, compliant with AEC-Q100 Grade 1 (−40 °C to +125 °C), featuring TTL-level inputs, 3.3 ns typical propagation delay at 5 V/15 pF, and Schmitt-trigger input action for noise immunity. It serves as a logic combiner in vehicle body control modules for fault-detection voting circuits.
For engineers reviewing the 74AHCT30D-Q100J datasheet, 74AHCT30D-Q100J pinout, 74AHCT30D-Q100J application, or 74AHCT30D-Q100J equivalent, key selection criteria include input voltage compatibility (TTL-level), propagation delay stability across temperature, SO14 package suitability for reflow-soldered automotive PCBs, and AEC-Q100 qualification evidence.
Technical Context
This device implements a single 8-input NAND function using high-speed Si-gate CMOS technology, pin-compatible with LSTTL. Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure direct interfacing with legacy 5 V microcontrollers and sensor outputs without level-shifting.
All eight inputs feature Schmitt-trigger action, providing hysteresis (typ. 0.3 V) that rejects fast transient noise on signal lines-critical in electrically noisy automotive environments. The output drives ±8 mA at VCC = 4.5 V, supporting fan-out to multiple downstream CMOS loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 8-input NAND gate; active-low output asserts only when all eight inputs are HIGH. |
| Supply Voltage Range | 4.5 V to 5.5 V; ensures robust operation under automotive battery transients (e.g., load dump). |
| Propagation Delay | 3.3 ns typ. (CL = 15 pF, VCC = 5 V); enables use in timing-critical control loops up to ~100 MHz effective toggle rate. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V (TTL-compatible); eliminates need for external level translators when interfacing with 5 V MCU GPIOs. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V; meets stringent automotive ESD immunity requirements per ISO 10605. |
| Operating Temperature | −40 °C to +125 °C ambient; qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications. |
Pinout & Package
SO14 plastic small outline package (SOT108-1), 14-lead, 3.9 mm body width, JEDEC MS-012 compliant, with gull-wing leads suitable for automated optical inspection and standard reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data input | First of eight logic inputs; accepts TTL-level signals; Schmitt-triggered for noise rejection. |
| 2 (B) | Data input | Second logic input; electrically identical to Pin 1; supports parallel voting logic trees. |
| 3 (C) | Data input | Third logic input; no internal pull-up/down; requires external bias if left floating in system design. |
| 4 (D) | Data input | Fourth logic input; shares same VIH/VIL specs and propagation delay as other inputs. |
| 5 (E) | Data input | Fifth logic input; compatible with 5 V digital rails without series resistors or clamping diodes. |
| 6 (F) | Data input | Sixth logic input; supports hot-swap tolerant designs when used with current-limiting series resistors. |
| 7 (GND) | Ground reference | 0 V return path for all internal circuitry; must be low-impedance connection to minimize ground bounce. |
| 8 (Y) | Data output | Inverted NAND result; drives CMOS/TTL loads up to ±8 mA; VOH ≥ 3.94 V at −8 mA (VCC = 4.5 V). |
| 9, 10, 13 (n.c.) | Not connected | No internal bond wire or silicon connection; must remain unconnected on PCB to avoid parasitic coupling. |
| 11 (G) | Data input | Seventh logic input; identical electrical behavior to Pins 1–6; used in full 8-input configuration. |
| 12 (H) | Data input | Eighth and final logic input; completes the 8-input NAND function; no special timing priority. |
| 14 (VCC) | Supply voltage | +4.5 V to +5.5 V power rail; requires local 100 nF ceramic decoupling capacitor within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including temperature cycling, HTOL, and ESD stress tests. |
| TTL-level input compatibility | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply enable direct interface with legacy 5 V MCUs and sensors without level shifters. |
| Schmitt-trigger inputs | Input hysteresis ≥ 0.3 V suppresses noise-induced false triggering on long harness traces or noisy power domains. |
| Low dynamic power dissipation | CPD = 12 pF enables <1 mW dynamic power at 1 MHz toggle rate, reducing thermal load in dense ECUs. |
| SO14 package with side-wettable flanks | SOT108-1 footprint supports automated optical inspection (AOI) of solder joints-critical for automotive process traceability. |
Applications

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 |
|---|---|---|---|
| 74AHC30D-Q100J | CMOS-level inputs (VIH ≥ 3.85 V @ VCC = 5.5 V); lower ICC (2 μA typ) | Better suited for mixed-voltage systems where upstream logic is 3.3 V or 5 V CMOS | Select when interfacing with modern low-voltage MCUs or when ultra-low static current is critical. |
| SN74LVX30QDRQ1 | TTL-compatible inputs (VIH ≥ 2.0 V), but rated only to +105 °C; not AEC-Q100 Grade 1 qualified | Limited to cabin electronics or non-critical subsystems; not approved for under-hood use | Acceptable for cost-sensitive non-safety applications where full AEC-Q100 Grade 1 is not mandated. |
Compared with 74AHC30D-Q100J and SN74LVX30QDRQ1, the 74AHCT30D-Q100J uniquely delivers AEC-Q100 Grade 1 qualification *plus* TTL-level input compatibility-making it the only choice for safety-critical 5 V automotive control nodes requiring both environmental robustness and legacy interface support.

FAQ
What is the maximum clock frequency supported by the 74AHCT30D-Q100J?
The 74AHCT30D-Q100J is a combinational logic gate-not a clocked device-so it has no defined clock frequency. Its usable toggle rate depends on propagation delay and load capacitance: with 15 pF load and 5 V supply, tpd = 3.3 ns (typ), enabling reliable operation up to ~100 MHz for repetitive input patterns. System-level timing must account for worst-case 8.0 ns delay at 125 °C.
Can unused inputs be left floating?
No. All eight inputs (Pins 1, 2, 3, 4, 5, 6, 11, 12) must be tied to a valid logic level-either VCC or GND-via ≤10 kΩ resistor. Floating inputs risk oscillation due to Schmitt-trigger hysteresis and may increase ICC, cause excessive heating, or induce EMI. Unused n.c. pins (9, 10, 13) must remain unconnected.
Does the 74AHCT30D-Q100J support mixed-voltage operation (e.g., 3.3 V inputs with 5 V VCC)?
No. The 74AHCT30D-Q100J is specified only for VCC = 4.5–5.5 V. Inputs accept voltages up to VCC + 0.5 V per limiting values, but TTL-level thresholds (VIH ≥ 2.0 V) assume VCC ≥ 4.5 V. Driving it with 3.3 V logic levels risks marginal VIH margin and is outside recommended operating conditions.
Is the SO14 package RoHS and REACH compliant?
Yes. The 74AHCT30D-Q100J in SOT108-1 package is manufactured per Nexperia's standard compliance program: lead-free (Pb-free), RoHS Directive 2011/65/EU compliant, and REACH SVHC-free as of the latest declaration. Full material declarations and certificates are available upon request through Aetrix Electronics' technical support.
