Product details
Overview
74HCT08D-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 (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 4.5–5.5 V supply range, and propagation delay of 14–36 ns (typ/max over temp). It serves as a logic-level combinatorial gate in vehicle body control modules for signal enable/interlock functions.
For engineers reviewing the 74HCT08D-Q100 datasheet, 74HCT08D-Q100 pinout, 74HCT08D-Q100 application, or 74HCT08D-Q100 equivalent, key selection criteria include automotive AEC-Q100 Grade 1 qualification, TTL input compatibility, SO14 thermal derating (10.1 mW/K above 100 °C), and guaranteed operation up to +125 °C ambient.
Technical Context
This device implements four independent 2-input AND logic functions using CMOS technology with TTL-level input thresholds, enabling direct interfacing with legacy 5 V TTL outputs without level shifting. Each gate features input clamp diodes supporting current-limiting resistor interface to voltages exceeding VCC.
It complies with JEDEC JESD8C (2.7–3.6 V) and JESD7A (2.0–6.0 V), supports HBM ESD >2000 V and CDM >1000 V, and exhibits latch-up immunity exceeding 100 mA per JESD78 Class II Level B.
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 | 4.5 V to 5.5 V - ensures compatibility with standard 5 V automotive power rails and stable TTL-level interfacing. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V (at VCC = 4.5–5.5 V) - guarantees reliable recognition of TTL logic levels without external biasing. |
| Propagation Delay | 14–36 ns (tpd, -40 °C to +125 °C, CL = 50 pF) - enables use in medium-speed digital control paths such as window lift enable sequencing. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cabin-mounted automotive ECUs. |
| Output Drive | ±4.0 mA (VOH/VOL at VCC = 4.5 V) - sufficient to drive multiple 74-series inputs or small LED indicators directly. |
| Power Dissipation | 500 mW max at Tamb ≤ 100 °C (SO14), derates 10.1 mW/K above - defines thermal design margin for PCB layout in sealed enclosures. |
Pinout & Package
74HCT08D-Q100 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, with gull-wing leads suitable for reflow soldering and AOI inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A (Pins 1, 4, 9, 12) | Data Input A | First input of each AND gate; accepts TTL-level signals with internal clamping diodes. |
| 1B, 2B, 3B, 4B (Pins 2, 5, 10, 13) | Data Input B | Second input of each AND gate; electrically identical to A inputs, fully interchangeable. |
| 1Y, 2Y, 3Y, 4Y (Pins 3, 6, 8, 11) | Data Output | AND result (nY = nA ∧ nB); drives CMOS/TTL loads up to ±4.0 mA at VCC = 4.5 V. |
| GND (Pin 7) | Ground Reference | 0 V return path for all logic and supply currents; must be low-impedance for noise immunity. |
| VCC (Pin 14) | Supply Voltage | Primary power rail (4.5–5.5 V); decoupling capacitor required within 10 mm for stable switching. |
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. |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V supply - eliminates need for level translators when interfacing with legacy microcontrollers or discrete logic. |
| Input clamp diodes | Enable safe interface to voltages > VCC via external current-limiting resistors - supports wake-up signal monitoring from higher-voltage domains (e.g., 12 V battery-sensed lines). |
| High noise immunity | Typical noise margin > 1.2 V at VCC = 5 V - suppresses false triggering in electrically noisy vehicle environments (e.g., near motors or ignition systems). |
| Low static current | ICC ≤ 40 μA at VCC = 5.5 V and full static conditions - minimizes quiescent power in always-on vehicle subsystems like door module standby logic. |
Applications
| Body Control Module Logic Enable | Instrument Cluster Signal Gating |
|---|---|
|

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 |
|---|---|---|---|
| 74HCT08PW-Q100 | TSSOP14 (SOT402-1) package; 0.65 mm pitch; 4.4 mm body width; Ptot derates 7.3 mW/K above 81 °C. | Better thermal performance in high-density layouts but requires finer-pitch reflow profile and AOI setup. | Select for space-constrained PCBs where SO14 footprint is unavailable and thermal mass is lower. |
| 74HCT08BQ-Q100 | DHVQFN14 (SOT762-1) package; 2.5 × 3 mm body; side-wettable flanks; Ptot derates 9.6 mW/K above 98 °C. | Superior thermal resistance and automated optical inspection capability, but requires stencil-defined solder paste volume control. | Select for thermally demanding locations (e.g., near power MOSFETs) and automated assembly lines with QFN-capable AOI. |
Compared with 74HCT08PW-Q100 and 74HCT08BQ-Q100, the 74HCT08D-Q100 offers the broadest reflow process window and highest mechanical robustness for manual repair or high-vibration environments, while maintaining identical logic behavior and AEC-Q100 qualification.

FAQ
Is 74HCT08D-Q100 pin-compatible with non-automotive 74HCT08 variants?
Yes - it shares identical pinout, electrical characteristics, and logic function with standard 74HCT08 devices in SO14 package. However, only the -Q100 suffix denotes AEC-Q100 Grade 1 qualification, including extended temperature validation, enhanced ESD testing, and automotive-specific reliability screening not present in commercial versions.
Can 74HCT08D-Q100 operate reliably at 4.0 V supply?
No - the 74HCT08D-Q100 is specified only for 4.5 V to 5.5 V operation per its recommended conditions. At 4.0 V, VIH minimum drops below 2.0 V and VOH degrades below TTL HIGH threshold, risking logic misreads; use 74HC08D-Q100 (2.0–6.0 V) if lower supply is required.
What is the purpose of the input clamp diodes in this device?
The internal clamp diodes allow safe connection of inputs to voltages exceeding VCC (e.g., 12 V wake-up lines) when used with external current-limiting resistors. They conduct excess voltage to VCC or GND, preventing damage and enabling direct interface without external protection components in automotive signal routing.
Does 74HCT08D-Q100 require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs must be terminated to VCC or GND to prevent floating states that cause increased ICC, oscillation, or EMI. The datasheet specifies VIH/VIL thresholds; leaving inputs unconnected violates recommended operating conditions and may induce unpredictable output behavior or excessive power consumption.
