Functional Description
The SCAN18374 consists of two sets of nine edge-triggered
flip-flops with individual D-type inputs and TRI-STATE true
outputs. The buffered clock and buffered Output Enable pins
are common to all flip-flops. Each set of the nine flip-flops will
store the state of their individual D inputs that meet the setup
and hold time requirements on the LOW-to-HIGH Clock

(ACP or BCP) transition. With the Output Enable (AOE
or
BOE
) LOW, the contents of the nine flip-flops are available
at the outputs. When the Output Enable is HIGH, the outputs
go to the high impedance state. Operation of the Output En-
able input does not affect the state of the flip-flops.
