SN74HCS72QDRQ1

Flip Flops Overview

The SN74HCS72QDRQ1 is an automotive-grade, dual D-type flip-flop featuring Schmitt-trigger inputs and push-pull outputs. It operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 105 MHz. The device exhibits a propagation delay of 7 ns with output currents of ±7.8 mA. Designed for harsh environments, it functions between -40°C and +125°C and holds AEC-Q100 qualification. Packaged in SOIC-14, this HCS series component provides balanced outputs and positive input clamp diodes for reliable signal integrity.

Flip Flops Feature Summary

• Schmitt-trigger inputs provide noise immunity and clean signal transitions.
• Automotive qualification ensures reliability under extreme temperature conditions.
• Push-pull outputs deliver balanced drive capability for robust performance.

Flip Flops Applications

• Automotive data acquisition systems requiring precise timing control
• Vehicle body electronics for state retention and logic sequencing
• Industrial control modules operating in high-noise environments

Flip Flops Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm that the AEC-Q100 grade aligns with the target automotive application requirements. Check datasheet revisions for any updates to electrical characteristics or recommended operating conditions before finalizing procurement specifications.

Flip Flops Selection Notes

Select this component when dual independent D-type storage with noise-tolerant inputs is required. The HCS technology offers higher speed than standard HC logic while maintaining low power consumption. Ensure the system voltage falls within the 2 V to 6 V range and that the SOIC-14 footprint fits the PCB layout constraints.

Flip Flops Part Context

This part belongs to Texas Instruments' SN74HCS family, which combines high-speed CMOS performance with automotive durability. The Q1 suffix indicates AEC-Q100 qualification, while the DRQ1 suffix specifies the SOIC-14 package with automotive-grade manufacturing. It serves as a foundational building block for sequential logic in safety-critical automotive designs.

Flip Flops Replacement Considerations

SN74HCS72-Q1 is the non-automotive qualified counterpart with identical electrical specifications but lacks AEC-Q100 certification. Verify if the automotive qualification is strictly necessary for the end-use environment before substituting.
