Product details
Overview
74AHCT08D-Q100 from Nexperia is an automotive-qualified quad 2-input AND gate in SO14 (SOT108-1) package, operating from -40 °C to +125 °C with TTL-compatible inputs, 5.5 V supply tolerance, and overvoltage-tolerant inputs up to 5.5 V. It serves as a level-translating logic gate in mixed-voltage automotive control modules, body electronics, and powertrain interface circuits.
For engineers reviewing the 74AHCT08D-Q100 datasheet, 74AHCT08D-Q100 pinout, 74AHCT08D-Q100 application, or 74AHCT08D-Q100 equivalent, this device is selected for AEC-Q100 Grade 1 compliance, balanced propagation delay (≤7.5 ns at VCC = 5.0 V, CL = 15 pF), Schmitt-trigger input hysteresis, and robust ESD protection (HBM >2000 V).
Technical Context
This device implements four independent 2-input AND logic functions with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) and CMOS-compatible output drive (VOH ≥ 3.7 V at IO = −8 mA, VOL ≤ 0.55 V at IO = 8 mA). All inputs feature Schmitt-trigger action for noise immunity and overvoltage tolerance up to 5.5 V regardless of VCC.
It operates across a wide ambient temperature range (−40 °C to +125 °C) and supports supply voltages from 4.5 V to 5.5 V. Static current consumption is ≤40 μA at VCC = 5.5 V, and dynamic power dissipation is characterized by CPD = 12.0 pF.
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 compatibility with standard 5 V automotive rails and noise margin |
| Propagation Delay | ≤7.5 ns at VCC = 5.0 V, CL = 15 pF - enables reliable timing in high-speed digital control loops |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - TTL-compatible switching levels for interfacing with legacy microcontrollers and sensors |
| Output Drive | ±8 mA - sufficient to drive multiple CMOS/TTL loads or small LED indicators directly |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive system-level ESD robustness requirements |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for engine bay and transmission control unit environments |
Pinout & Package
SO14 plastic small outline package (SOT108-1), 14-lead, body width 3.9 mm, lead pitch 1.27 mm, compliant with JEDEC MS-012.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input of each AND gate - accepts TTL-level signals up to 5.5 V independent of VCC |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input of each AND gate - Schmitt-triggered for noise rejection on noisy automotive buses |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Respective AND outputs - rail-to-rail CMOS outputs capable of driving 8 mA sink/source |
| 7 | GND | Digital ground reference - must be connected to system ground plane for stable logic operation |
| 14 | VCC | Positive supply input - decoupling capacitor (100 nF) required within 5 mm for noise suppression |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including thermal cycling and humidity testing |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V on any input pin regardless of VCC - enables safe interfacing with higher-voltage subsystems |
| Schmitt-trigger inputs | Provides hysteresis (typ. 0.3–0.5 V) to reject noise on slow-rising signals such as switch debouncing or sensor outputs |
| Low static power | ICC ≤ 40 μA at VCC = 5.5 V - reduces quiescent current in always-on vehicle modules |
| Side-wettable flanks not applicable | SO14 package (SOT108-1) lacks side-wettable flanks - AOI requires top-surface solder inspection only |

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 |
|---|---|---|---|
| 74AHCT08PW-Q100 | TSSOP14 package (SOT402-1), 4.4 mm body width, thinner profile, same electrical specs | Better thermal resistance (7.3 mW/K derating above 81 °C) and smaller PCB footprint | Select for space-constrained modules requiring automated optical inspection (AOI) of fine-pitch leads |
| 74AHCT08BQ-Q100 | DHVQFN14 package (SOT762-1), 2.5 × 3 mm, no leads, side-wettable flanks, same electrical specs | Superior thermal performance (9.6 mW/K derating above 98 °C), enhanced solder joint reliability verification | Select for high-density automotive ECUs where thermal management and process yield are critical |
Compared with 74AHCT08D-Q100, the PW variant offers board-area reduction and improved manufacturability in fine-pitch assembly, while the BQ variant delivers superior thermal dissipation and AOI-capable solder joints - all retain identical logic behavior, AEC-Q100 Grade 1 qualification, and TTL input compatibility.

FAQ
Is 74AHCT08D-Q100 pin-compatible with standard 74HC08 or 74LS08?
No. While functionally identical as a quad 2-input AND gate, 74AHCT08D-Q100 uses TTL-level inputs (VIH ≥ 2.0 V), unlike 74HC08 (CMOS inputs, VIH ≥ 3.85 V at VCC = 5.5 V) and 74LS08 (lower drive strength, different VOH/VOL). Pinout matches industry-standard SO14 logic packages, but voltage thresholds and output drive differ.
Can 74AHCT08D-Q100 operate at 3.3 V supply?
No. The 74AHCT08 variant is specified only for 4.5 V to 5.5 V operation per Table 5. For 3.3 V systems, use the 74AHC08D-Q100 variant, which has CMOS input thresholds and supports VCC = 2.0–5.5 V.
What is the significance of "overvoltage-tolerant inputs" in automotive use?
Inputs tolerate up to 5.5 V regardless of VCC, allowing safe connection to higher-voltage domains (e.g., 5 V sensor outputs) without external level shifters or clamping diodes - critical for fault-tolerant design in mixed-supply vehicle networks.
Does the SO14 package support automatic optical inspection (AOI)?
The SO14 (SOT108-1) package does not have side-wettable flanks. AOI is limited to top-surface solder joint inspection; for full-joint AOI capability, select the DHVQFN14 (74AHCT08BQ-Q100) or TSSOP14 (74AHCT08PW-Q100) variants.
