The Fairchild MM74HC374J is an 8-bit D-type flip-flop with tri-state, non-inverted outputs, clocked on the positive edge. It runs on a 2V to 6V supply and drives 7.8 mA per output.
Package and footprint
The MM74HC374J ships in a DIP package, bulk format. That through-hole footprint is still common on prototype boards, industrial I/O cards, and legacy backplane designs where a surface-mount reflow step is avoided. The 8-bit width and single-element layout (one 8-bit register per package) keeps the board routing clean for byte-wide data buses.
Lifecycle and sourcing
That means you can specify it into a new BOM without planning an obsolescence workaround. RoHS status is non-compliant, so if your assembly line requires lead-free solder, you will need to verify acceptance or plan for a waiver.
