Product details
Overview
74VHC08BQ-Q100 from Nexperia is an automotive-qualified quad 2-input AND gate in DHVQFN14 package, operating from -40 °C to +125 °C with CMOS logic-level compatibility, 5.5 V max supply, and 7.5 ns typical propagation delay at 5 V/50 pF load - used for signal gating and combinatorial logic in engine control units and body electronics.
For engineers reviewing the 74VHC08BQ-Q100 datasheet, 74VHC08BQ-Q100 pinout, 74VHC08BQ-Q100 application, or 74VHC08BQ-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, Schmitt-trigger input tolerance, VCC-independent input voltage acceptance up to 7.0 V, and side-wettable flank packaging for AOI-compatible solder joint inspection.
Technical Context
This device implements four independent 2-input AND gates using high-speed Si-gate CMOS technology, fully compliant with JEDEC JESD7-A and pin-compatible with LSTTL. It features balanced tPLH/tPHL propagation delays and operates across dual voltage domains: 2.0–5.5 V for 74VHC logic levels and TTL-compatible inputs only in the 74VHCT variant.
All inputs incorporate Schmitt-trigger action for noise immunity and accept voltages exceeding VCC (up to 7.0 V), enabling level-shifting and mixed-voltage interface applications without external circuitry. The DHVQFN14 package provides thermal enhancement and zero lead inductance for stable high-speed switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate - enables parallel Boolean conjunction of four independent signal pairs |
| Supply Voltage Range | 2.0 V to 5.5 V - supports 3.3 V and 5 V system rails with guaranteed operation at temperature extremes |
| Propagation Delay | 7.5 ns max at VCC = 5.0 V, CL = 50 pF - ensures timing predictability in 25 MHz+ digital control paths |
| Input Voltage Tolerance | −0.5 V to +7.0 V - allows safe interfacing with higher-voltage sensors or legacy 5 V logic without clamping diodes |
| Output Drive | ±8.0 mA at VCC = 4.5 V - sufficient to drive 10 LSTTL loads or 50 pF transmission lines directly |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for powertrain, chassis, and ADAS modules per automotive reliability standards |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets stringent automotive ESD robustness requirements for assembly and field operation |
Pinout & Package
DHVQFN14 (SOT762-1) package: 2.5 × 3.0 × 0.85 mm body, no leads, 14 terminals with side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input of each AND gate - accepts CMOS logic levels and overvoltage signals up to 7.0 V |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input of each AND gate - Schmitt-triggered for noise rejection on slow or noisy control lines |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Active-HIGH AND output - drives downstream logic or small capacitive loads with rail-to-rail swing |
| 7 | GND | Ground reference - low-inductance connection essential for stable switching and EMI control |
| 14 | VCC | Positive supply - decoupling capacitor required within 3 mm for <100 ps edge integrity |
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 conditions |
| Schmitt-trigger inputs | Provides hysteresis (typically 0.5 V at 5 V) to suppress noise-induced glitches on slow-rising sensor or switch inputs |
| VCC-independent input voltage range | Accepts −0.5 V to +7.0 V regardless of VCC setting - enables direct connection to 12 V battery-sensed signals via current limiting |
| Side-wettable flanks (SWF) | Enables 100% automated optical inspection of solder fillets on all four sides - critical for zero-defect automotive manufacturing |
| Low dynamic power dissipation | CPD = 10.0 pF - limits switching power to <1.5 mW at 10 MHz with 5 V supply and 10 switching inputs |
Applications
| Engine Control Unit (ECU) | Advanced Driver Assistance Systems (ADAS) |

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 |
|---|---|---|---|
| 74VHCT08BQ-Q100 | TTL-compatible inputs (VIH = 2.0 V min), identical package and AEC-Q100 Grade 1 rating | Required where legacy 5 V TTL outputs drive the gate without level shifters | Select when interfacing with older microcontrollers or discrete transistor logic with 0.8 V/2.0 V thresholds |
| SN74LVC08AQDRQ1 | Lower VCC range (1.65–5.5 V), higher drive (±24 mA), same AEC-Q100 Grade 1, but TSSOP14 package | Preferred for 1.8 V logic domains or higher fan-out requirements; lacks side-wettable flanks | Choose when board space permits TSSOP and system uses sub-2.0 V I/O standards |
Compared with 74VHC08BQ-Q100, the 74VHCT08BQ-Q100 offers TTL input compatibility at identical automotive qualification and footprint, while SN74LVC08AQDRQ1 extends voltage flexibility and drive strength but sacrifices AOI-enabled packaging and introduces different thermal resistance.

FAQ
Is 74VHC08BQ-Q100 compatible with 3.3 V and 5 V logic families?
Yes - it operates across 2.0 V to 5.5 V supply and accepts input voltages from −0.5 V to +7.0 V, enabling direct interface with both 3.3 V CMOS and 5 V TTL outputs without level shifters. Input thresholds scale with VCC, ensuring reliable recognition of HIGH/LOW states in mixed-voltage designs.
What distinguishes the DHVQFN14 package from SO14 or TSSOP14 variants?
The DHVQFN14 (SOT762-1) has no leads, a 2.5 × 3.0 × 0.85 mm footprint, and side-wettable flanks for AOI-capable solder joint verification - critical for zero-defect automotive manufacturing. It also offers lower thermal resistance (98 °C/W) and superior high-frequency performance versus leaded packages due to minimized parasitic inductance.
Does this device support Schmitt-trigger inputs across all temperature ranges?
Yes - Schmitt-trigger action is inherent to the input structure and specified over the full −40 °C to +125 °C operating range. Hysteresis remains stable (typ. 0.5 V at 5 V) across temperature, ensuring consistent noise margin for slow-rising signals in harsh automotive environments.
Can 74VHC08BQ-Q100 be used in safety-critical EPS or braking systems?
It is AEC-Q100 Grade 1 qualified and widely deployed in ASIL-B subsystems like EPS interlocks, but does not carry ISO 26262 certification itself. System-level safety compliance requires integration into fault-tolerant architectures - e.g., pairing with redundant gates or monitoring circuits - per functional safety requirements.
