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.

Features

■ Inputs and outputs on opposite sides of package allowing easy interface with microprocessors
