My current project calls for a SN7474 Dual D-Type flip-flop

This component does not appear in your catalogue so I am interested to learn what alternatives might exist.

Here is the datasheet:

Would this be similar to part [SN74F74D](https://www.digikey.com/en/products/detail/texas-instruments/SN74F74D/277203)

Here is a link to the datasheet.
