Product details
Overview
74AHCT00BQ-Q100 from Nexperia is an automotive-grade quad 2-input NAND gate in DHVQFN14 package, operating from -40 °C to +125 °C with TTL-compatible inputs, 5.5 V overvoltage-tolerant inputs, and propagation delay of 3.3–9.0 ns (VCC = 4.5–5.5 V, CL = 15–50 pF). It serves as a level-translating logic gate in mixed-voltage automotive control modules.
For engineers reviewing the 74AHCT00BQ-Q100 datasheet, 74AHCT00BQ-Q100 pinout, 74AHCT00BQ-Q100 application, or 74AHCT00BQ-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, input voltage compatibility across 3.3 V/5 V domains, Schmitt-trigger input hysteresis, thermal-enhanced DHVQFN packaging, and guaranteed operation up to +125 °C ambient.
Technical Context
This device implements four independent 2-input NAND logic functions with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) and rail-to-rail CMOS outputs. All inputs feature Schmitt-trigger action for noise immunity and tolerate up to 5.5 V regardless of supply voltage.
It supports mixed-voltage interfacing via overvoltage-tolerant inputs and operates across a wide temperature range (-40 °C to +125 °C), meeting AEC-Q100 Grade 1 requirements. Propagation delays are balanced between rising and falling edges (tPLH ≈ tPHL), and dynamic power dissipation is characterized by CPD = 7.0 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND gate - provides four independent Boolean NOT-AND operations per package |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V automotive systems and tolerance to supply ripple |
| Input Thresholds | TTL-compatible: VIH ≥ 2.0 V, VIL ≤ 0.8 V - enables direct interfacing with legacy 5 V TTL outputs without level shifters |
| Propagation Delay | 3.3 ns (typ) to 9.0 ns (max) at VCC = 4.5–5.5 V, CL = 15–50 pF - defines maximum clock/data rate support in combinatorial logic paths |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood and powertrain control unit environments per AEC-Q100 Grade 1 |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - ensures robustness during PCB handling and assembly in automotive manufacturing |
| Input Overvoltage Tolerance | Up to 5.5 V independent of VCC - allows safe connection to higher-voltage signal sources in mixed-supply systems |
Pinout & Package
DHVQFN14 (SOT762-1) package: 2.5 × 3.0 × 0.85 mm body, no leads, side-wettable flanks for AOI-compatible solder joint inspection, exposed thermal pad (non-electrical, optional GND connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A (pins 1, 4, 9, 12) | Input A of gates 1–4 | Primary logic inputs accepting TTL-level signals; overvoltage tolerant to 5.5 V |
| 1B, 2B, 3B, 4B (pins 2, 5, 10, 13) | Input B of gates 1–4 | Secondary logic inputs with identical electrical specs as A inputs; enable full NAND functionality |
| 1Y, 2Y, 3Y, 4Y (pins 3, 6, 8, 11) | Output Y of gates 1–4 | CMOS rail-to-rail outputs capable of sinking 8 mA or sourcing 8 mA at VCC = 4.5 V |
| GND (pin 7) | Ground reference | 0 V return path for all internal circuitry and output loads; required for stable logic thresholds |
| VCC (pin 14) | Positive supply | Primary power input (4.5–5.5 V); powers all four gates and internal input protection networks |
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 per stress test conditions |
| Overvoltage-tolerant inputs | Accepts input voltages up to 5.5 V regardless of VCC setting - eliminates need for external clamping diodes in mixed-voltage nodes |
| Schmitt-trigger inputs | Provides hysteresis on all inputs (typ. 0.3–0.5 V) - rejects high-frequency noise and prevents metastability on slow-rising signals |
| DHVQFN14 with side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on bottom terminations - improves process yield in SMT automotive assembly lines |
| Low dynamic power dissipation | CPD = 7.0 pF - limits switching power to < 175 μW per gate at 1 MHz and VCC = 5 V, reducing thermal load in dense layouts |
Applications
| Body Control Module (BCM) | Powertrain Control Unit (PCU) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT00PW-Q100 | TSSOP14 package (4.4 mm width), no side-wettable flanks, same electrical specs and AEC-Q100 qualification | Suitable for manual rework or prototyping; lacks AOI capability for high-volume automotive SMT | Select when board space permits larger footprint and AOI is not required in final production line. |
| SN74AHCT00QPWRQ1 | Texas Instruments part in TSSOP14; identical logic function and AEC-Q100 Grade 1 rating; VIH/VIL tolerances match within 0.1 V | Same functional behavior but different package thermal resistance and ESD performance (HBM > 4000 V) | Choose for TI-design ecosystems or where higher HBM margin is prioritized over Nexperia's DHVQFN thermal advantage. |
Compared with 74AHCT00PW-Q100 and SN74AHCT00QPWRQ1, the 74AHCT00BQ-Q100 offers superior thermal performance and automated optical inspectability due to its DHVQFN14 package with side-wettable flanks - critical for high-reliability automotive SMT lines where solder joint integrity must be verified non-destructively.

FAQ
Is the exposed thermal pad on the DHVQFN14 package electrically connected?
No. The exposed pad (pin 1 index area) is not electrically connected to any internal node. Per datasheet note, it may remain floating or be connected to GND if soldered - but no electrical or mechanical requirement exists to do so. Its primary purpose is thermal conduction, not grounding.
Can 74AHCT00BQ-Q100 operate with a 3.3 V supply?
No. The 74AHCT00BQ-Q100 variant is specified only for VCC = 4.5 V to 5.5 V, as confirmed in Table 5 (Recommended Operating Conditions). For 3.3 V operation, the 74AHC00BQ-Q100 variant (CMOS-input version) is required - it supports VCC down to 2.0 V and has different input threshold specifications.
What is the significance of "Side-Wettable Flanks" in the DHVQFN14 package?
Side-wettable flanks refer to vertical metal sidewalls on each terminal that become visibly soldered during reflow. This enables automated optical inspection (AOI) systems to verify solder joint formation on bottom-terminated packages - a critical quality assurance requirement for automotive electronics manufacturing where X-ray inspection is cost-prohibitive at scale.
Does this device support hot insertion or live swapping in powered systems?
No. While inputs are overvoltage tolerant up to 5.5 V, the device lacks Ioff (power-off protection) or bus-hold features. Applying inputs before VCC is stable may cause undefined output states or increased ICC. Hot-swap operation requires explicit power sequencing control per datasheet Section 8 recommendations.
