Product details
Overview
74AHCT30BQ-Q100 from Nexperia is an automotive-qualified 8-input NAND gate in DHVQFN14 package, operating from -40 °C to +125 °C with TTL-level inputs, 3.3–5.5 V supply range, and propagation delay as low as 3.3 ns (CL = 15 pF, VCC = 5 V). It delivers balanced timing, Schmitt-trigger inputs, and input overvoltage tolerance up to 7.0 V - used in automotive body control modules for logic-level signal conditioning and bus arbitration.
For engineers reviewing the 74AHCT30BQ-Q100 datasheet, 74AHCT30BQ-Q100 pinout, 74AHCT30BQ-Q100 application, or 74AHCT30BQ-Q100 equivalent, key selection criteria include automotive AEC-Q100 Grade 1 qualification, DHVQFN thermal performance, TTL-compatible input thresholds, and verified 8-input NAND truth table compliance under extended temperature.
Technical Context
This device implements a single 8-input NAND function using high-speed Si-gate CMOS technology, fully compliant with JEDEC 7-A and 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 interoperability with legacy 5 V logic families.
All eight inputs feature Schmitt-trigger action, enabling noise-immune signal reception and hysteresis of typically 0.3–0.5 V. Input voltage tolerance extends to ±0.5 V beyond VCC (up to 7.0 V), supporting mixed-voltage interface scenarios without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 8-input NAND gate with active-low output; implements Boolean Y = NOT(A·B·C·D·E·F·G·H) |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures stable operation across automotive battery variations (e.g., cold-crank transients) |
| Propagation Delay | 3.3 ns typical (CL = 15 pF, VCC = 5 V) - enables use in high-speed control loops with sub-10 ns timing budgets |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees reliable interfacing with standard 5 V TTL outputs |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive environments |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets stringent automotive ESD immunity requirements |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small capacitive loads (<50 pF) |
Pinout & Package
DHVQFN14 (SOT762-1) package: 2.5 × 3.0 × 0.85 mm body, side-wettable flanks for AOI-compatible solder joint inspection, thermally enhanced exposed pad (non-electrical unless connected to GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference (0 V); required for biasing and noise return path |
| 2–6, 11–12 | A–H | Eight independent logic inputs; each features Schmitt-trigger action and overvoltage tolerance |
| 7 | n.c. | No internal connection; must be left floating or tied to GND for mechanical stability |
| 8 | Y | Inverted NAND output; drives downstream logic with rail-to-rail swing (VOH/VOL specified at ±8 mA) |
| 9–10, 13 | n.c. | Three additional no-connect terminals; no internal bond wire or circuitry attached |
| 14 | VCC | Positive supply input; decoupling capacitor (100 nF) required within 5 mm for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including lifetime reliability testing |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints on bottom-side terminations |
| TTL-compatible input levels | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply - eliminates need for external level translation with legacy controllers |
| Schmitt-trigger inputs | Provides 300–500 mV hysteresis per input, rejecting noise on slow-rising signals (e.g., switch debouncing) |
| Input overvoltage tolerance | Accepts VI up to 7.0 V regardless of VCC - supports hot-swap and mixed-supply interface robustness |
Applications
| Body Control Module Logic | Powertrain Sensor Interface |
|---|---|
|
Use Scenario: Combining eight discrete sensor status flags (e.g., door open, seatbelt latch, trunk release, hood ajar) into a single fault-enable signal. IC Role / Device Role / Timing Role: 8-input NAND acts as a wired-OR fault aggregator - output goes LOW only when all eight conditions are asserted, triggering system warning. Use Value: Reduces MCU GPIO count by 7 pins while maintaining deterministic, glitch-free fault detection without software polling overhead. |
Use Scenario: Validating synchronized readiness of eight engine sensors (cam/crank position, MAP, IAT, ECT, O2 pre/post, knock, MAF) before enabling fuel injection. IC Role / Device Role / Timing Role: NAND gate serves as a hardware "all-ready" arbiter - output HIGH only if every sensor reports valid data. Use Value: Enables fail-safe startup sequence with <10 ns timing uncertainty, independent of firmware execution latency or interrupt jitter. |
| ADAS Camera Power Sequencing | Infotainment System Bus Arbitration |
|
Use Scenario: Enabling camera module power rails only after eight subsystems (IMU, GPS, CAN, LIN, thermal, lens, flash, ISP) confirm initialization completion. IC Role / Device Role / Timing Role: Acts as final hardware interlock - NAND output controls high-side load switch enabling 12 V/3.3 V rails. Use Value: Prevents partial power-up states that cause image corruption or thermal runaway, with zero firmware dependency. |
Use Scenario: Resolving contention between eight infotainment peripherals (touch controller, audio codec, display driver, BT/WiFi, USB hub, SD card, CAN gateway, LIN master) sharing a common I²C bus. IC Role / Device Role / Timing Role: NAND output feeds enable input of bus buffer - activates only when all peripherals signal "ready" (HIGH). Use Value: Eliminates bus lock-up during cold boot by enforcing strict hardware handshake before clock/data lines become active. |
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 |
|---|---|---|---|
| 74AHC30BQ-Q100 | CMOS-level inputs (VIH = 3.85 V min at VCC = 5.5 V); lower ICC (2 μA typ vs. 20 μA) | Requires 3.3 V or 5 V CMOS drivers; unsuitable for direct TTL interfacing | Select when interfacing exclusively with modern microcontrollers or FPGAs with CMOS outputs |
| SN74LVX30QPWRQ1 | TI's AEC-Q100 Grade 1 8-input NAND; LV family (1.65–3.6 V), smaller 14-pin TSSOP package | Not 5 V tolerant; incompatible with 5 V sensor buses or legacy ECUs | Prefer for low-voltage (1.8/3.3 V) ADAS domain controllers where space and power are critical |
Compared with 74AHCT30BQ-Q100, the 74AHC30BQ-Q100 offers lower static current but lacks TTL compatibility, while SN74LVX30QPWRQ1 supports lower voltage operation but cannot interface with 5 V automotive peripherals - making the AHCT variant uniquely suited for mixed-voltage automotive subsystem integration.

FAQ
Is the exposed thermal pad on the DHVQFN14 package electrically connected?
No - the exposed pad (terminal 1 index area) is not electrically connected to any internal node. Nexperia specifies it may remain floating or be soldered to GND for thermal enhancement, but no electrical requirement exists. If connected, it must be isolated from VCC and signal traces.
Can 74AHCT30BQ-Q100 safely interface with 3.3 V microcontrollers?
Yes, but only when the microcontroller outputs meet TTL voltage thresholds: VOH ≥ 2.4 V and VOL ≤ 0.4 V at 3.3 V supply. Many 3.3 V MCUs satisfy this; verify output specs before use. For guaranteed compatibility, add a pull-up resistor to 5 V on MCU outputs or use level translators.
What is the maximum capacitive load this device can drive reliably?
At VCC = 5 V and Tamb = 125 °C, the device maintains tpd ≤ 10.5 ns driving CL = 50 pF. Driving >50 pF increases propagation delay nonlinearly and risks output waveform degradation; for >50 pF loads, add a buffer stage or reduce trace length and parasitic capacitance.
Does the "n.c." marking on pins 7, 9, 10, and 13 imply they must be left unconnected?
Pins 9, 10, and 13 are true no-connects with no internal bonding - they must be left floating or tied to GND for mechanical stability. Pin 7 is labeled "GND" in the pin description table and is the functional ground terminal; it must be connected to the system ground plane with low-inductance routing.
