SN74AHCT74QPWRG4Q1

Flip Flops Overview

The SN74AHCT74QPWRG4Q1 is an automotive-grade dual positive-edge-triggered D-type flip-flop from Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs with CMOS outputs. The device provides non-inverting Q and inverting Q' outputs, each capable of sourcing or sinking 8 mA. It exhibits a propagation delay of 8.8 ns and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a 14-pin TSSOP, it holds AEC-Q100 qualification for automotive applications.

Flip Flops Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free RoHS compliance and specific tape-and-reel packaging configuration. Ensure the AEC-Q100 qualification status aligns with your specific automotive application requirements. Confirm the TSSOP-14 package dimensions match your PCB footprint design constraints before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with TTL-compatible inputs is required for 5V automotive logic systems. The AHCT series ensures compatibility with legacy TTL signaling while offering CMOS output drive strength. Consider the TSSOP-14 package for space-constrained designs requiring surface-mount assembly. Verify that the 8.8 ns propagation delay meets the timing specifications of your target circuit application.

Flip Flops Part Context

This device belongs to the SN74AHCT74Q family of automotive-grade logic components. It shares functional similarities with the SN74HC74QPWRG4Q1 but differs in input compatibility, utilizing TTL thresholds instead of CMOS thresholds. The Q1 designation indicates automotive qualification, distinguishing it from standard commercial variants. It serves as a digital storage element within larger logic networks.

Flip Flops Replacement Considerations

The SN74AHCT74QDRG4Q1 offers identical electrical characteristics but utilizes a SOIC-14 package instead of TSSOP-14. Designers must verify footprint compatibility when substituting between these package types. Other family members like the SN74AHCT74QPWRQ1 may exist without the G4 suffix, indicating potential differences in lead-free compliance or packaging details.
