DESCRIPTION:
The IDT54/74FCT377T is an octal D flip-flop built using an advanced
dual metal CMOS technology. The IDT54/74FCT377T has eight edge-
triggered, D-type flip-flops with individual D inputs and O outputs. The
common buffered Clock (CP) input loads all flip-flops 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 flip-flop鈥檚 O output. The
CE
input must be
stable only one set-up time prior to the low-to-high transition for predictable
operation.
