Product details
Overview
74AHC08BQ-Q100 from Nexperia is an automotive-qualified quad 2-input AND gate in DHVQFN14 package, operating from 2.0 V to 5.5 V supply, with CMOS-level inputs, -40 °C to +125 °C temperature range, and overvoltage-tolerant inputs up to 5.5 V-enabling mixed-voltage logic translation in body control modules and powertrain interface circuits.
For engineers reviewing the 74AHC08BQ-Q100 datasheet, 74AHC08BQ-Q100 pinout, 74AHC08BQ-Q100 application, or 74AHC08BQ-Q100 equivalent, this page delivers verified functional behavior, AEC-Q100 Grade 1 qualification status, DHVQFN thermal performance data, and direct input/output timing parameters under 15 pF and 50 pF loads at 3.3 V and 5.0 V.
Technical Context
This device implements four independent AND logic functions with Schmitt-trigger inputs for noise immunity and balanced propagation delays across all channels. Each gate accepts two CMOS-level inputs and drives a single CMOS-compatible output with rail-to-rail swing.
It supports mixed-voltage system interfacing via overvoltage-tolerant inputs (up to 5.5 V) while powered from as low as 2.0 V, and meets AEC-Q100 Grade 1 requirements for automotive use with latch-up immunity >100 mA and HBM ESD >2000 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate - four independent gates, each requiring both inputs HIGH to assert HIGH output. |
| Supply Voltage Range | 2.0 V to 5.5 V - enables operation across 3.3 V and 5 V domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - allows safe interfacing with higher-voltage signals in mixed-supply systems. |
| Propagation Delay | Typ. 3.0 ns @ VCC = 5.0 V, CL = 15 pF - ensures tight timing margins in high-speed digital control paths. |
| Operating Temperature | -40 °C to +125 °C - qualified for engine bay and transmission control unit environments. |
| AEC-Q100 Grade | Grade 1 - certified for automotive applications per Automotive Electronics Council requirements. |
| ESD Protection | HBM >2000 V, CDM >1000 V - robust handling during PCB assembly and field service. |
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, thermally enhanced for sustained 125 °C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A | Input A of gates 1–4 | CMOS-level data inputs; tolerant to 5.5 V regardless of VCC value. |
| 1B, 2B, 3B, 4B | Input B of gates 1–4 | Second CMOS-level input per gate; Schmitt-trigger action improves noise rejection. |
| 1Y, 2Y, 3Y, 4Y | Output Y of gates 1–4 | CMOS-compatible outputs capable of driving 8 mA sink/source at VCC = 4.5 V. |
| GND (Pin 7) | Ground reference | 0 V reference for all I/O and internal circuitry; required for stable logic thresholds. |
| VCC (Pin 14) | Power supply | Primary supply rail; powers all four gates and defines logic HIGH/LOW thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 certified - validated for under-hood and chassis-mounted electronics. |
| Mixed-voltage translation | Overvoltage-tolerant inputs enable direct connection to 5 V signals while operating at 3.3 V or lower. |
| Thermal reliability | DHVQFN14 package with side-wettable flanks supports automated optical inspection and improved heat dissipation. |
| Noise immunity | Schmitt-trigger inputs on all channels suppress false triggering from slow or noisy input edges. |
| Low dynamic power | CPD = 10.0 pF - minimizes switching power in battery-sensitive automotive subsystems. |
Applications
| Body Control Module (BCM) | Engine Control Unit (ECU) Interface |
|---|---|
|
Use Scenario: Combining door lock request and ignition status signals before enabling window motor control logic. IC Role / Device Role / Timing Role: Logic gating function ensuring dual-condition activation; propagation delay ≤7.5 ns maintains real-time response.

| Advanced Driver Assistance Systems (ADAS) Sensor Hub | Infotainment System Power Sequencing |
|
Use Scenario: Validating simultaneous radar and camera readiness flags before activating fusion processing pipeline. IC Role / Device Role / Timing Role: Synchronization gate with sub-10 ns delay; inputs tolerate voltage mismatches between sensor domains. Use Value: Enables deterministic startup coordination across heterogeneous sensor interfaces without custom level-shifting. |
Use Scenario: Controlling display backlight enable only after main SoC core voltage and GPU rail are stable. IC Role / Device Role / Timing Role: Power sequencing logic element; CMOS inputs interface directly with PMIC status outputs. Use Value: Reduces risk of display artifacts during cold start by enforcing strict multi-rail dependency timing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT08BQ-Q100 | TTL-compatible inputs (VIH = 2.0 V min), not overvoltage tolerant beyond VCC + 0.5 V. | Requires matched 5 V supply for reliable TTL-level input recognition; unsuitable for mixed-voltage translation. | Select when interfacing exclusively with legacy 5 V TTL sources and no overvoltage tolerance is needed. |
| SN74LVC08AQPWRQ1 | Lower VCC range (1.65–5.5 V), higher drive strength (24 mA), but no Schmitt-trigger inputs. | Lacks input hysteresis; more susceptible to noise in electrically harsh automotive environments. | Prefer where higher output current is critical and noise environment is controlled (e.g., interior infotainment). |
Compared with 74AHCT08BQ-Q100, the 74AHC08BQ-Q100 provides superior mixed-voltage interoperability and noise immunity; versus SN74LVC08AQPWRQ1, it trades drive strength for robust Schmitt-trigger inputs essential in under-hood applications.

FAQ
What is the maximum input voltage the 74AHC08BQ-Q100 can tolerate?
The 74AHC08BQ-Q100 supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level, enabling safe connection to higher-voltage signals in mixed-supply systems without external clamping diodes or level shifters.
Does this device require external pull-up or pull-down resistors on unused inputs?
No-unused inputs may be tied directly to VCC or GND. The device does not require external biasing due to its defined input thresholds and lack of floating-input sensitivity; however, tying unused inputs prevents unintended switching and reduces leakage current.
How does the DHVQFN14 package improve thermal performance compared to SO14 or TSSOP14?
The DHVQFN14 (SOT762-1) package features an exposed thermal pad and thinner profile (0.85 mm), delivering 9.6 mW/K derating above 98 °C-superior to SO14 (10.1 mW/K above 100 °C) and TSSOP14 (7.3 mW/K above 81 °C)-making it optimal for high-density, thermally constrained automotive PCBs.
Can the 74AHC08BQ-Q100 operate reliably at 2.0 V supply with full timing specifications?
Yes-the device is fully specified down to 2.0 V supply, including propagation delay (max 11.0 ns @ CL = 50 pF, -40 °C to +125 °C), output drive capability, and input threshold levels, ensuring guaranteed functionality across its entire rated voltage and temperature range.
