Functional Description
The ABT574 consists of eight edge-triggered flip-flops with
individual D-type inputs and 3-STATE true outputs. The
buffered clock and buffered Output Enable are common to
all flip-flops. The eight flip-flops will store the state of their
individual D inputs that meet the setup and hold times
requirements on the LOW-to-HIGH Clock (CP) transition.

With the Output Enable (OE) LOW, the contents of the
eight flip-flops are available at the outputs. When OE is
HIGH, the outputs are in a high impedance state. Opera-
tion of the OE input does not affect the state of the flip-
flops.
