Flip Flops Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TVSOP-14 surface-mount package and reel packaging format. Confirm that the AHCT logic family designation ensures correct 5V operation and TTL input threshold compatibility for your system design. Ensure RoHS compliance requirements are met by checking the manufacturer's current documentation for this specific part number.

Flip Flops Selection Notes

Select this component when dual edge-triggered storage is required in a 5V environment. The AHCT series offers faster switching speeds compared to standard HCT while maintaining TTL input compatibility. Consider the TVSOP-14 package size for space-constrained PCB layouts. Verify that the asynchronous control inputs meet the timing requirements of your application.

Flip Flops Part Context
