SN74AHC74RGYRG4

Flip Flops Overview

The SN74AHC74RGYRG4 is a dual positive-edge-triggered D-type flip-flop with clear and preset functions, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features CMOS inputs and outputs. The device is housed in a 14-VQFN package (3.5x3.5 mm) with exposed pad for thermal enhancement. Key electrical parameters include a maximum propagation delay of 15.4 ns, high-level output current of -8 mA, and low-level output current of 8 mA. It supports an operating temperature range from -40°C to +125°C and complies with RoHS standards.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flops with independent clear and preset control inputs
• CMOS input and output structure ensuring compatibility with standard logic families
• Wide operating supply voltage range supporting both 2V and 5.5V systems
• Exposed thermal pad design in VQFN package for improved heat dissipation

Flip Flops Applications

• Digital data storage and register applications
• Shift registers in communication interfaces
• Timing and synchronization circuits
• State machine implementations in embedded systems

Flip Flops Procurement Notes

Verify the complete part number including the RG4 suffix, which indicates RoHS compliance and lead-free status. Confirm the package type matches the 14-VQFN specification with exposed pad. Ensure the supplier provides official datasheets referencing the SN74AHC74 series. Check moisture sensitivity level (MSL 2) requirements for handling and storage conditions prior to assembly.

Flip Flops Selection Notes

Select this component when dual D-type flip-flops with asynchronous clear and preset are required in space-constrained designs. The VQFN package offers a compact footprint suitable for surface-mount applications. Consider the 15.4 ns propagation delay for timing-critical paths. Ensure the system voltage falls within the 2V to 5.5V range. Compare against other AHC series variants if single flip-flop or different package options are needed.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74AHC74 family of dual D-type flip-flops. The 'AHC' designation indicates advanced high-speed CMOS technology. The 'RGYR' suffix specifies the 14-VQFN package with tape and reel packaging. The 'G4' suffix denotes environmental compliance. It is functionally equivalent to other SN74AHC74 variants but differs in package and packaging format.

Flip Flops Replacement Considerations

SN74AHC74RGYR is the non-RoHS version of the same package. SN74AHC74DRG4 is the SOIC-14 package variant. SN74AHC74PW is the TSSOP-14 option. Verify pinout compatibility and thermal performance when substituting packages.
