Product details
Overview
74AHC08D-Q100 from Nexperia is an automotive-qualified quad 2-input AND gate in SO14 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 voltage translation in mixed-rail automotive control modules.
For engineers reviewing the 74AHC08D-Q100 datasheet, 74AHC08D-Q100 pinout, 74AHC08D-Q100 application, or 74AHC08D-Q100 equivalent, key selection factors include AEC-Q100 Grade 1 qualification, propagation delay ≤7.5 ns at 5 V/50 pF, input Schmitt-trigger action, balanced tPLH/tPHL timing, and SO14 package compatibility with legacy PCB footprints.
Technical Context
This device implements four independent 2-input AND logic functions with true CMOS input thresholds (VIH ≥3.85 V at VCC = 5.5 V), enabling interoperability with 3.3 V and 5 V logic domains. Each gate features Schmitt-trigger inputs for noise immunity and overvoltage tolerance up to 5.5 V on all I/O pins regardless of VCC level.
It operates across two automotive temperature grades: -40 °C to +125 °C (fully specified per Table 5), with static output drive capability of ±8 mA at VCC = 4.5 V and dynamic power dissipation governed by CPD = 10.0 pF, supporting low-noise, low-power digital interfacing in engine control units and body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate - provides four independent Boolean AND operations in one package |
| Supply Voltage Range | 2.0 V to 5.5 V - supports direct interface with 3.3 V and 5 V microcontrollers and sensors |
| Propagation Delay | ≤7.5 ns at VCC = 5.0 V, CL = 50 pF - ensures timing-critical synchronization in automotive serial bus interfaces |
| Input Threshold | VIH = 3.85 V (min) at VCC = 5.5 V - guarantees TTL-compatible high-level recognition with margin |
| Output Drive | ±8.0 mA at VCC = 4.5 V - sufficient to drive multiple CMOS loads or small LED indicators without buffering |
| Temperature Range | -40 °C to +125 °C - fully qualified for under-hood and transmission-control applications |
| AEC-Q100 Grade | Grade 1 - certified for automotive use with validated reliability under thermal cycling, humidity, and vibration stress |
Pinout & Package
SO14 plastic small outline package (SOT108-1), 14-lead, 3.9 mm body width, with gull-wing leads and standard 1.27 mm pitch - compatible with automated SMT assembly and AOI inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A | Data input A for gates 1–4 | CMOS-level inputs accepting 0–5.5 V; tolerant of overvoltage even when VCC = 2.0 V |
| 1B, 2B, 3B, 4B | Data input B for gates 1–4 | Independent second inputs per gate; each includes Schmitt-trigger hysteresis for noise rejection |
| 1Y, 2Y, 3Y, 4Y | Output Y for gates 1–4 | Push-pull CMOS outputs capable of sourcing/sinking ±8 mA at 4.5 V |
| GND (Pin 7) | Ground reference | Primary 0 V return path; must be low-impedance for stable logic thresholds and noise immunity |
| VCC (Pin 14) | Positive supply | Single supply rail powering all four gates; decoupling capacitor required within 1 cm |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across -40 °C to +125 °C with HTOL, TC, HAST, and ESD testing per JEDEC standards |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V on any input pin regardless of VCC setting - enables safe level-shifting between 3.3 V and 5 V subsystems |
| Schmitt-trigger inputs | Hysteresis of ~0.3 V typical - suppresses false triggering from slow or noisy signals in chassis-ground-referenced environments |
| Low dynamic power | CPD = 10.0 pF - limits switching current in high-frequency enable/control paths, reducing EMI and local heating |
| ESD robustness | HBM >2000 V, CDM >1000 V - withstands handling and board-level transients common in automotive manufacturing |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
|
Use Scenario: Combining crankshaft position and camshaft sync signals to validate engine timing before fuel injection activation. IC Role / Device Role / Timing Role: Logic enable gate ensuring dual-sensor agreement prior to critical actuation. Use Value: Prevents misfire events by enforcing hardware-level AND validation before software permits injector firing. |
Use Scenario: Enabling door lock actuation only when both central locking command and door ajar status are asserted. IC Role / Device Role / Timing Role: Safety interlock gate preventing unintended lock/unlock during door motion. Use Value: Adds fail-safe hardware layer that remains functional even if MCU firmware hangs or resets. |
| Instrument Cluster Display | Advanced Driver Assistance System (ADAS) Sensor Interface |
|
Use Scenario: Gating backlight enable signal with ignition-on status to prevent display illumination during cranking. IC Role / Device Role / Timing Role: Power sequencing gate synchronizing display readiness with vehicle power state. Use Value: Eliminates brown-out flicker and extends LCD driver lifetime by avoiding partial-power operation. |
Use Scenario: Validating simultaneous detection from forward radar and camera object classifiers before issuing lane-keep alert. IC Role / Device Role / Timing Role: Sensor fusion arbitration gate requiring consensus before safety-critical output assertion. Use Value: Reduces false positives by enforcing hardware-level agreement between heterogeneous sensor modalities. |
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 |
|---|---|---|---|
| 74AHCT08D-Q100 | TTL-compatible inputs (VIH = 2.0 V min), identical pinout and packaging | Better suited for interfacing with legacy 5 V TTL outputs; slightly higher ICC at VCC = 5 V | Select when driving from older 5 V logic families; avoid if interfacing with modern 3.3 V CMOS microcontrollers |
| SN74LVC08AQDRQ1 | Lower VCC range (1.65–5.5 V), LVTTL/CMOS hybrid inputs, same SO14 footprint | Supports 1.8 V logic domains; lacks Schmitt-trigger inputs and AEC-Q100 Grade 1 full characterization | Choose for multi-voltage systems needing 1.8 V compatibility; verify noise immunity requirements separately |
Compared with 74AHC08D-Q100, the 74AHCT08D-Q100 offers TTL input compatibility at the cost of reduced noise margin in mixed-voltage designs, while SN74LVC08AQDRQ1 extends voltage flexibility downward but omits Schmitt-triggering and full Grade 1 qualification-making the AHC variant optimal for new 3.3/5 V automotive logic interfacing where robustness and noise immunity are prioritized.

FAQ
Is 74AHC08D-Q100 pin-compatible with non-automotive 74AHC08 variants?
Yes - it shares identical SO14 pinout (SOT108-1), electrical characteristics, and logic function with industrial-grade 74AHC08D. The Q100 suffix denotes AEC-Q100 qualification and extended temperature testing; no pin or functional changes are introduced.
Can 74AHC08D-Q100 interface directly between 3.3 V and 5 V logic domains?
Yes - its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC level, and its CMOS outputs swing rail-to-rail. When powered at 3.3 V, it reliably receives 5 V inputs and drives 3.3 V loads without external level shifters.
What is the significance of Schmitt-trigger inputs in this device?
Schmitt-trigger inputs provide hysteresis (~0.3 V typical), raising the VIH threshold after a HIGH transition and lowering VIL after a LOW transition. This prevents chatter on slow-rising signals like those from mechanical switches or long harness runs in automotive environments.
Does 74AHC08D-Q100 require external pull-up or pull-down resistors on unused inputs?
No - all inputs have internal protection and defined logic states when floating, but best practice is to tie unused inputs to VCC or GND. Leaving them unconnected risks increased ICC and potential oscillation due to noise coupling, especially in high-EMI automotive settings.
