Product details
Overview
74VHCT08D-Q100 from Nexperia is an automotive-qualified quad 2-input AND gate in SO14 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 level-translating logic combiner in body control modules and powertrain interface circuits.
For engineers reviewing the 74VHCT08D-Q100 datasheet, 74VHCT08D-Q100 pinout, 74VHCT08D-Q100 application, or 74VHCT08D-Q100 equivalent, this page delivers verified automotive-grade logic timing, input compatibility, thermal derating behavior, and SO14 mechanical interface data - all confirmed against Nexperia's Rev. 3 (22 April 2024) product data sheet.
Technical Context
This device implements four independent AND gates using high-speed Si-gate CMOS technology, fully compliant with JEDEC JESD7-A and AEC-Q100 Grade 1 qualification. Its TTL-compatible inputs accept standard 5 V logic levels while driving CMOS loads, enabling seamless integration between legacy TTL subsystems and modern low-power controllers.
All inputs feature Schmitt-trigger action for noise immunity, support overvoltage tolerance up to 7.0 V, and exhibit balanced tPLH/tPHL propagation delays. The SO14 package (SOT108-1) provides 3.9 mm body width, 1.27 mm lead pitch, and linear power derating of 10.1 mW/K above 100 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate - four independent gates, each requiring both inputs HIGH to assert HIGH output |
| Supply Voltage Range | 4.5 V to 5.5 V - supports stable operation across automotive battery transients and regulated 5 V rails |
| Propagation Delay | 7.9 ns typ (VCC = 5 V, CL = 50 pF) - enables reliable timing in sub-100 MHz digital control loops |
| Output Drive | ±8 mA - sufficient to directly drive multiple 74-series inputs or small LED indicators without buffering |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - ensures robust recognition of TTL-level signals across full temperature range |

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 |
|---|---|---|---|
| 74VHC08D-Q100 | CMOS-input version (VIH = 3.85 V min at VCC = 5.5 V); lower ICC (2 μA typ) | Requires CMOS-level inputs; unsuitable for direct TTL signal interfacing | Select when interfacing exclusively with 3.3 V or 5 V CMOS sources and ultra-low static power is critical |
| SN74LV08AQDRQ1 | Texas Instruments part; VIH = 2.0 V min, VIL = 0.8 V max, but only rated to +105 °C (not Grade 1) | Lacks full AEC-Q100 Grade 1 qualification; not approved for under-hood deployment | Acceptable for cabin electronics where ambient temperature stays below +105 °C and Grade 1 is not mandated |
Compared with 74VHC08D-Q100 and SN74LV08AQDRQ1, the 74VHCT08D-Q100 uniquely delivers TTL-level input compatibility *plus* full AEC-Q100 Grade 1 qualification across -40 °C to +125 °C - making it the only choice for safety-critical, high-temperature automotive logic gating.

FAQ
What is the maximum allowable input voltage for 74VHCT08D-Q100?
The absolute maximum input voltage is +7.0 V, referenced to GND, regardless of VCC state. This overvoltage tolerance allows safe interfacing with higher-voltage subsystems or transient-prone lines without external clamping diodes - confirmed in Table 4 (Limiting Values) of the Rev. 3 datasheet.
Does 74VHCT08D-Q100 support mixed-voltage operation (e.g., 3.3 V inputs with 5 V VCC)?
No - the 74VHCT08D-Q100 is strictly a 5 V-only device. Its TTL-compatible inputs require VCC = 4.5–5.5 V to meet specified VIH/VIL thresholds; operation at 3.3 V VCC is not characterized or guaranteed, and input thresholds degrade outside this range.
How does the SO14 package's thermal derating affect power dissipation at 125 °C ambient?
For SOT108-1 (SO14), total power dissipation derates linearly at 10.1 mW/K above 100 °C. At 125 °C ambient, Ptot is reduced by (25 K × 10.1 mW/K) = 252.5 mW from the 500 mW rating at ≤100 °C, yielding ~247.5 mW maximum usable power - per Table 4 footnote [2].
Can unused inputs be left floating in automotive applications?
No - all inputs must be actively driven HIGH or LOW. Floating inputs cause increased ICC, unpredictable output states, and potential latch-up due to internal parasitic structures. Tie unused inputs to VCC or GND via ≤1 kΩ resistor to ensure stability and meet AEC-Q100 reliability requirements.
