Product details
Overview
74VHCT08BQ-Q100 from Nexperia is an automotive-qualified quad 2-input AND 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), 7.9 ns typical propagation delay (VCC = 5 V, CL = 50 pF), and ±8 mA output drive. It serves as a logic-level combiner in automotive body control modules for signal gating and enable control.
For engineers reviewing the 74VHCT08BQ-Q100 datasheet, 74VHCT08BQ-Q100 pinout, 74VHCT08BQ-Q100 application, or 74VHCT08BQ-Q100 equivalent, this page delivers verified pin functions, AEC-Q100 Grade 1 qualification status, DHVQFN14 thermal performance data, TTL-level compatibility details, and validated automotive use cases - all extracted directly from Nexperia's Rev. 3 (22 April 2024) product data sheet.
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 AEC-Q100 Grade 1 for automotive use. Its TTL-compatible inputs accept standard 5 V logic levels while driving CMOS loads with rail-to-rail output swing.
It features Schmitt-trigger action on all inputs, enabling noise immunity in electrically harsh environments, and supports input voltages up to 7.0 V regardless of VCC - critical for robustness during load-dump transients in vehicle power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate - provides four independent Boolean AND operations per package |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures stable operation across automotive battery variations (e.g., cold-crank to load-dump) |
| Propagation Delay | 7.9 ns typical (VCC = 5.0 V, CL = 50 pF) - enables timing-critical control sequencing in BCM and lighting modules |
| Output Drive | ±8.0 mA - sufficient to directly interface with multiple downstream CMOS inputs or small-signal LEDs without buffering |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees reliable recognition of legacy TTL outputs in mixed-logic automotive subsystems |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood and cabin-mounted ECUs per AEC-Q100 Grade 1 |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive assembly and handling requirements per JS-001/JS-002 |
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, thermal-enhanced construction for sustained operation in high-ambient automotive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input of each AND gate - accepts TTL/CMOS logic signals; Schmitt-triggered for noise rejection |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input of each AND gate - identical electrical behavior to A inputs; enables dual-signal gating |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Output of each AND gate - CMOS-compatible rail-to-rail swing, capable of sourcing/sinking ±8 mA |
| 7 | GND | Ground reference (0 V) - must be low-impedance connection to minimize switching noise coupling |
| 14 | VCC | Positive supply (4.5–5.5 V) - requires local 100 nF ceramic decoupling adjacent to pin 14 |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling, HTOL, and ESD stress tests |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints on bottom-terminated DHVQFN package - improves manufacturing yield in SMT lines |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply - ensures interoperability with legacy microcontrollers and discrete logic in automotive clusters |
| Balanced propagation delays | tPLH and tPHL match within 0.5 ns (typ.) - prevents duty-cycle distortion in clocked enable paths and synchronous gating applications |
| Input overvoltage tolerance | Accepts VI up to 7.0 V independent of VCC - protects against transient overvoltages during battery jump-start or alternator regulation faults |
Applications
| Body Control Module (BCM) Signal Gating | Automotive Lighting Enable Logic |
|---|---|
|
Use Scenario: Enabling headlight relay drivers only when both ignition-on and light-switch signals are asserted. IC Role / Device Role / Timing Role: Quad AND gate performing synchronous two-signal validation before power-stage activation. Use Value: Eliminates need for microcontroller GPIO polling; reduces BOM count by replacing firmware-based logic with deterministic hardware gating. |

IC Role / Device Role / Timing Role: Hardware-level combinatorial logic block interfacing analog comparator output and CAN-derived speed signal. Use Value: Ensures sub-10 ns response to sensor inputs - faster than MCU interrupt latency - for immediate DRL activation on motion detection. |
| Door Lock Actuator Interlock | Instrument Cluster Warning Logic |
|
Use Scenario: Preventing simultaneous lock/unlock actuation by requiring exclusive enable signals from driver and passenger door switches. IC Role / Device Role / Timing Role: Dual AND gate implementing mutual exclusion logic between two independent mechanical switch inputs. Use Value: Provides fail-safe hardware arbitration that remains functional even if main ECU resets or experiences software hang. |
Use Scenario: Activating brake warning lamp only when both brake pedal switch is closed AND ABS fault flag is active.

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 |
|---|---|---|---|
| 74VHC08BQ-Q100 | CMOS-input version (VIH = 3.85 V min at VCC = 5.5 V); higher noise margin but incompatible with TTL sources | Requires CMOS-level upstream drivers; unsuitable for direct interface with legacy 5 V TTL microcontrollers | Select when system uses exclusively CMOS logic families and demands highest noise immunity. |
| SN74LVC08APWRQ1 | Lower VCC range (1.65–5.5 V); 3.3 V optimized; no AEC-Q100 Grade 1 rating (only Q100-compliant) | Limited to 3.3 V domains; lacks full Grade 1 temperature validation for under-hood placement | Prefer for cost-sensitive 3.3 V infotainment subsystems where full Grade 1 qualification is not required. |
Compared with 74VHC08BQ-Q100 and SN74LVC08APWRQ1, the 74VHCT08BQ-Q100 uniquely bridges legacy 5 V TTL signaling and modern automotive thermal/safety requirements - making it the only option qualified for Grade 1 operation while accepting standard TTL input levels.

FAQ
What is the maximum allowable input voltage for 74VHCT08BQ-Q100 when VCC = 5.0 V?
The absolute maximum input voltage is +7.0 V, per Table 4 (Limiting Values). This overvoltage tolerance applies regardless of VCC level and enables safe operation during automotive load-dump events (ISO 7637-2 Pulse 5a), where transient spikes can exceed 60 V on supply lines - provided input current remains within ±20 mA clamping limits.
Does 74VHCT08BQ-Q100 support mixed-voltage operation (e.g., 3.3 V inputs with 5 V supply)?
No - the 74VHCT08BQ-Q100 is strictly a 5 V-only device. Its TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) are specified only for VCC = 4.5–5.5 V. Applying 3.3 V logic signals violates the recommended operating conditions and may result in unreliable switching or increased static current due to partial device turn-on.
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), achieving 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). This allows sustained 500 mW total power dissipation at higher ambient temperatures common in engine-bay-mounted ECUs.
Is 74VHCT08BQ-Q100 pin-compatible with non-automotive 74VHCT08 variants?
Yes - it shares identical pinout, electrical characteristics, and package dimensions (SOT762-1) with industrial-grade 74VHCT08BQ. The "-Q100" suffix denotes AEC-Q100 qualification testing and screening; no pin or functional differences exist. Designers may substitute for qualification upgrade without layout changes.
