Functional Description
The FCT273T consists of eight edge-triggered D-type
flip-flops with individual D inputs and Q outputs. The common
buffered clock (CP) and master reset (MR) load and reset all
flip-flops simultaneously. The FCT273T is an edge-triggered
register. The state of each D input (one set-up time before the
LOW-to-HIGH clock transition) is transferred to the corre-
sponding flip-flop’s Q output. All outputs will be forced LOW by
a low voltage level on the MR input.
The outputs are designed with a power-off disable feature to
allow for live insertion of boards.
