74AHC273D-Q100J

Overview

The Nexperia 74AHC273D-Q100J is an automotive-grade octal D-type flip-flop with a positive-edge clock and asynchronous reset, belonging to the AHC logic family. It operates within a supply voltage range of 2.0 V to 5.5 V and features low power dissipation with high noise immunity. The component is housed in a SOIC-20 package (SOT163) and complies with AEC-Q100 qualification standards for automotive applications. It supports operation across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards
• Octal configuration providing eight independent D-type flip-flops
• Asynchronous reset functionality for immediate state clearing
• Positive-edge clock triggering mechanism

Applications

• Automotive data bus systems requiring robust signal storage
• Vehicle electronic control units (ECUs) for memory management
• Industrial automation controllers needing reliable sequential logic
• High-noise environments utilizing CMOS-compatible inputs

Procurement Notes

Verify that the specific part number suffix matches the required package variant, as the 'D' designation indicates the SOIC-20 form factor. Confirm AEC-Q100 certification status is explicitly documented in the official datasheet for your target application's regulatory requirements. Ensure compatibility with your system's voltage levels and temperature specifications before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits that demand high-density octal storage within a single integrated circuit package. It is suitable for applications requiring precise timing synchronization via positive-edge clocking. Consider its AHC technology benefits for lower power consumption compared to standard HC series devices while maintaining compatible input/output characteristics.

Part Context

This device is part of Nexperia's extensive portfolio of automotive-qualified logic integrated circuits. It complements other components in the 74AHC-Q100 family, offering standardized pinouts and electrical characteristics. The product line supports various packaging options to accommodate different board space constraints and thermal management needs in modern electronic designs.

Replacement Considerations

Direct substitutes include other manufacturers' octal D-type flip-flops meeting AEC-Q100 standards. Verify pinout compatibility and electrical parameter equivalence, particularly regarding propagation delay and output drive current. Alternative packages such as TSSOP-20 may require schematic adjustments due to differing physical dimensions.
