DESCRIPTION
The 74LVC377 is a low-voltage Si-gate CMOS device, superior to
most advanced CMOS compatible TTL families.
The 74LVC377 has eight edge-triggered , D-type flip-flops with
individual D inputs and Q outputs. A common clock (CP) input loads
all flip-flops simultaneously when the data enable E is LOW. The
state of each D input, one set-up time before the LOW-to-HIGH
clock transition, is transferred to the corresponding output (Qn) of
the flip-flop. The E input must be stable only one set-up time prior to
the LOW-to-HIGH transition for predictable operation.
