74HC273D-Q100J

Overview

The Nexperia 74HC273D-Q100J is an octal D-type flip-flop with reset, designed for automotive applications. It operates within a supply voltage range of 2.0 V to 6.0 V and features positive-edge triggering on the clock input. The device includes a master reset function that forces outputs low independently of clock and data inputs. It is housed in a SOIC-20 package and complies with AEC-Q100 qualification standards.

Feature Summary

• Octal configuration providing eight independent positive-edge triggered D-type flip-flops
• Master reset input allows synchronous or asynchronous clearing of all outputs
• Automotive-grade qualification ensuring reliability under harsh environmental conditions
• High noise immunity and latch-up performance exceeding standard JEDEC requirements

Applications

• Automotive data acquisition systems requiring robust memory elements
• Vehicle control unit interfaces for signal latching and buffering
• Industrial logic circuits demanding high noise immunity and wide voltage operation

Procurement Notes

Verify component authenticity by checking the manufacturer's official documentation against the part marking. Confirm that the specific suffix matches the requested automotive grade and package type. Ensure compliance with RoHS and REACH regulations as stated in the product environment files. Cross-reference the ordering code with the distributor's catalog to avoid substitution errors during procurement.

Selection Notes

Select this component when an octal storage element with a global reset is required for automotive environments. Consider the SOIC-20 package for surface-mount assembly constraints. Evaluate the 2.0 V to 6.0 V operating range against system power rails. Verify that the positive-edge trigger timing aligns with the system clock specifications and hold time requirements.
