74AHCT273D-Q100J

Overview

The Nexperia 74AHCT273D-Q100J is an automotive-grade octal D-type flip-flop with a positive-edge trigger, belonging to the AHC logic family. It features eight independent D-type flip-flops in a single package, providing data storage and synchronization capabilities for digital systems. The component is qualified under AEC-Q100 standards, ensuring reliability for harsh automotive environments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from -40 °C to +125 °C. The device is housed in a SOIC-20 surface-mount package, facilitating compact PCB layouts.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for enhanced reliability
• Octal configuration integrating eight independent D-type flip-flops
• Positive-edge triggering mechanism for precise data synchronization
• Wide operating temperature range suitable for demanding automotive applications

Applications

• Automotive electronic control units requiring robust data latching
• Industrial automation systems utilizing high-reliability logic components
• Consumer electronics with extended temperature operational requirements

Procurement Notes

Verify the specific suffix J indicates reel packaging when ordering. Confirm that the AEC-Q100 qualification aligns with target application stress levels. Ensure input voltage levels match TTL specifications due to the AHCT series designation. Check lead times as automotive-grade components may have longer production cycles compared to standard commercial variants.

Selection Notes

Select this component when an octal flip-flop solution is required for automotive or industrial designs. The AHCT series ensures compatibility with TTL input levels while offering AHC speed performance. Consider the SOIC-20 package size for space-constrained layouts. Validate thermal management requirements given the 125 °C maximum junction temperature specification.

Part Context

This part belongs to Nexperia's 74AHC/AHCT automotive logic portfolio, designed for high-speed switching with low power consumption. The 74AHCT273 variant specifically provides octal D-type functionality, distinguishing it from quad configurations like the 74AHCT74. It complements other automotive logic gates such as NAND and NOR functions within the same product line.

Replacement Considerations

Direct substitutes include the 74AHC273D-Q100J (non-TTL input compatible) and 74AHCT273PW-Q100J (TSSOP-20 package). Verify pinout compatibility and electrical characteristics before substitution. Cross-reference with other manufacturers' automotive-grade octal flip-flops if supply constraints exist.
