Product details
Overview
74HCT00BQ-Q100 from Nexperia is an automotive-qualified quad 2-input NAND gate in DHVQFN14 package, operating from -40 °C to +125 °C with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 4.32 V VOH at -4.0 mA, and 24 ns typical propagation delay at VCC = 4.5 V - used for logic-level signal inversion and combinatorial control in engine control units and body electronics.
For engineers reviewing the 74HCT00BQ-Q100 datasheet, 74HCT00BQ-Q100 pinout, 74HCT00BQ-Q100 application, or 74HCT00BQ-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, DHVQFN14 thermal performance, TTL-level input compatibility, output drive capability (-4.0 mA/4.0 mA), and 14-terminal side-wettable flank geometry for AOI-enabled solder joint inspection.
Technical Context
This device implements four independent 2-input NAND gates using CMOS silicon with TTL-compatible input stage circuitry, enabling direct interfacing with legacy 5 V TTL logic families without level-shifting. Each gate features input clamp diodes allowing safe operation with input voltages exceeding VCC when current-limited.
The DHVQFN14 package (SOT762-1) provides enhanced thermal dissipation (9.6 mW/K derating above 98 °C) and mechanical robustness for automotive under-hood environments, while its side-wettable flanks support automated optical inspection of solder joints - a critical requirement for high-reliability automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND: four independent gates, each performing Y = NOT(A AND B) |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard 5 V automotive rail with ±0.5 V tolerance |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures reliable recognition of TTL logic levels |
| Output Drive | VOH ≥ 3.7 V at -4.0 mA, VOL ≤ 0.4 V at 4.0 mA - supports fan-out of ≥10 LS-TTL loads |
| Propagation Delay | 24 ns typical (max 29 ns) at VCC = 4.5 V, CL = 50 pF - enables <40 MHz toggle rate in synchronous logic |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for powertrain and chassis modules |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - exceeds automotive ESD immunity requirements for assembly and field operation |
Pinout & Package
DHVQFN14 package (SOT762-1): 2.5 × 3.0 × 0.85 mm body, no leads, 14 terminals, side-wettable flanks, exposed thermal pad (non-electrical, optional GND connection).

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT00PW-Q100 | TSSOP14 package (SOT402-1); 4.4 mm body width; 7.3 mW/K thermal derating above 81 °C | Higher profile and lower thermal efficiency than DHVQFN; less suitable for under-hood high-temp zones | Select when board layout requires gull-wing leads or reworkability outweighs thermal performance |
| SN74HCT00QPWRQ1 | Texas Instruments part in TSSOP14; identical logic function and AEC-Q100 Grade 1 rating; VIH = 2.0 V min | Same package limitations as 74HCT00PW-Q100; different ESD specs (HBM > 4000 V vs. >2000 V) | Choose only if TI supply chain integration or dual-sourcing strategy mandates TI branding |
Compared with 74HCT00PW-Q100 and SN74HCT00QPWRQ1, the 74HCT00BQ-Q100 offers superior thermal management and AOI-capable packaging - making it the preferred choice for high-density, thermally constrained automotive modules where long-term reliability under sustained 125 °C operation is mandatory.

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. Per datasheet note, it has no electrical or mechanical requirement to be soldered; if connected, it must remain floating or tied to GND - it does not serve as a ground terminal by default.
Can 74HCT00BQ-Q100 operate reliably at 3.3 V supply?
No. The 74HCT00BQ-Q100 is specified only for 4.5 V to 5.5 V operation per Table 5. At 3.3 V, VIH minimum (2.0 V) becomes invalid relative to VCC, risking incorrect logic interpretation; use 74HC00BQ-Q100 instead for 2.0–6.0 V wide-range operation.
What is the maximum output current per pin during continuous DC operation?
The absolute maximum output current is ±25 mA per pin (Table 4), but recommended steady-state operation limits to ±4.0 mA (Table 6) to maintain VOH ≥ 3.7 V and VOL ≤ 0.4 V across temperature - exceeding this risks output voltage degradation and increased propagation delay variation.
Does this device support hot insertion or live hot-swap operation?
No. The datasheet does not specify hot-insertion capability. Input clamp diodes protect against brief overvoltage but do not guarantee safe power-rail sequencing during live insertion; external hot-swap controllers or sequencing ICs are required for such applications.
