DESCRIPTION:
The IDT54/74AHCT377 is an octal D flip-flop built using
advanced CEMOS'", a dual metal CMOS technology. The
IDT54174AHCT377 has eight edge-triggered, D-type flip-flops
with individual D inputs and 0 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 setup time before the LOW-to-HIGH
clock transition, is transferred to the corresponding flip-flop's
o output. The CE input must be stable only one setup time priorto
the LOW-to-HIGH clock transition for predictable operation.
