Overview
The Nexperia 74AHCT02BQ-Q100X is a high-speed Si-gate CMOS quad 2-input NOR gate qualified to AEC-Q100 Grade 1. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features balanced propagation delays, Schmitt-trigger inputs, and overvoltage tolerant inputs up to 7.0 V. It utilizes a DHVQFN14 package (SOT762-1) with side-wettable flanks for automatic optical inspection.
Feature Summary
- Automotive qualification in accordance with AEC-Q100 Grade 1 standards
- All inputs feature Schmitt-trigger action for noise immunity
- Inputs accept voltages higher than the supply voltage VCC
- DHVQFN package includes side-wettable flanks enabling AOI
Applications
- Automotive electronic systems requiring robust logic gates
- Mixed voltage environments utilizing TTL level inputs
- High-speed digital signal processing circuits
Procurement Notes
Verify that the specific ordering suffix matches the required tape and reel configuration. Confirm the package variant corresponds to the DHVQFN14 form factor. Ensure the component grade aligns with automotive reliability requirements before finalizing procurement orders.
Selection Notes
Select this component when TTL-compatible input levels are necessary within an automotive environment. The AHCT series ensures compatibility with Low-power Schottky TTL logic families while providing the speed benefits of CMOS technology. Verify thermal dissipation capabilities against the specific application load conditions.
Part Context
This part belongs to the Nexperia 74AHC_AHCT02-Q100 family of quad 2-input NOR gates. It shares functional characteristics with other members of the series but differs in package type and electrical specifications tailored for specific industrial and automotive applications.
Replacement Considerations
Direct pin-compatible substitutes include the standard 74AHCT02D and 74AHCT02PW variants. Non-automotive equivalents such as the 74AHC02 or 74LVC00ABQ may function electrically but lack the required AEC-Q100 qualification.
