Functional Description
The FCT377T has eight triggered D-type 鏗俰p-鏗俹ps with
individual D inputs. The common buffered clock inputs (CP)
loads all 鏗俰p-鏗俹ps simultaneously when the Clock Enable (CE)
is LOW. The register is fully edge-triggered. The state of each
D input, one set-up time before the LOW-to-HIGH clock
transition, is transferred to the corresponding 鏗俰p-鏗俹p鈥檚 O out-
put. The CE input must be stable only one set-up time prior to
the LOW-to-HIGH clock transition for predictable operation.
The outputs are designed with a power-off disable feature to
allow for live insertion of boards.
