Overview
The SN74AHCT08QWBQARQ1 is an automotive-grade quadruple 2-input positive-AND gate utilizing EPIC™ enhanced-performance implanted CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from -40°C to +125°C. The device features TTL-compatible inputs, enabling up-level translation from 3.3 V sources to 5 V logic levels. Electrical characteristics include low-level output current of 8 mA and high-level output current of -8 mA. Propagation delay ranges from 1 ns to 9 ns depending on load capacitance. The component is housed in a 14-pin WQFN (BQA) package with dimensions of 3.00 mm × 2.50 mm.
Feature Summary
- Qualified for automotive applications using EPIC™ process technology
- TTL-voltage compatible inputs allow up translation from 3.3 V to 5 V
- Low-drive outputs provide slow rise and fall times to minimize signal ringing
Applications
- Combining power good signals
- Combining enable signals
- Bus-interface applications requiring low-noise outputs
Procurement Notes
Verify the specific BQA package designation and Q1 automotive qualification suffix during procurement. Confirm that the thermal pad connection requirements align with the target PCB layout design. Ensure bypass capacitor placement adheres to recommended guidelines to prevent power disturbances. Validate input conditions against specified VIH and VIL thresholds for reliable operation.
Selection Notes
Select this component when automotive qualification and AEC-Q100 standards are required. Choose this part for designs needing TTL compatibility to interface 3.3 V logic with 5 V systems. Consider the WQFN package for space-constrained layouts requiring a thermal pad for improved heat dissipation compared to standard SOIC or TSSOP options.
Part Context
This device belongs to the SN74AHCT08Q-Q1 family of automotive quadruple 2-input positive-AND gates. It shares functional specifications with other variants in the series but utilizes the WQFN (BQA) package type. The family is designed for robust performance in demanding automotive environments while maintaining compatibility with standard TTL logic levels.
Replacement Considerations
Direct substitutes within the same family include SN74AHCT08QDRQ1 (SOIC package) and SN74AHCT08QPWRQ1 (TSSOP package). Verify pinout compatibility and package dimensions before substitution.
