Flip Flops Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and green manufacturing status as per Texas Instruments documentation. Confirm the SOIC-14 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet for any recent product change notifications that may affect pinout or electrical characteristics before finalizing procurement.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with wide voltage compatibility is required. The LVC series offers lower power consumption compared to older HC/HCT families while maintaining similar performance. Consider the 24mA drive strength for driving moderate loads directly. Verify that the 6.8ns propagation delay satisfies your system timing constraints. The SOIC-14 package provides a balance between pin count and board space efficiency.

Flip Flops Part Context

This part belongs to the SN74LVC74A family of dual D-type flip-flops. It shares functional similarities with other LVC logic devices but is optimized for low-voltage operation. The 'R' suffix denotes tape and reel packaging, suitable for automated surface-mount assembly processes. It is distinct from automotive-grade variants which carry additional qualification markings.

Flip Flops FAQ

Does the SN74LVC74ADRG4 include internal pull-up resistors?

No, the datasheet does not specify internal pull-up resistors for the set, reset, or clock inputs. External resistors may be required depending on the application design.

What is the maximum switching speed of this device?

The device supports a maximum clock frequency determined by its propagation delay. At 3.3V, the typical propagation delay is approximately 6.8ns under standard load conditions.
