74ABT574
Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The ABT574 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 ABT374 but has
broadside pinouts.
