54FCT574 Datasheet (National Semiconductor)

54FCT574, Octal D-Type Flip-Flop

The ’FCT574 is an octal flip-flop with a buffered common Clock (CP) and a buffered common Output Enable (OE).

The information presented to the D inputs is stored in the flip-flops on the LOW-to-HIGH Clock (CP) transition.

The device is functionally identical to the ’FCT374 except for the pinouts.
