DESCRIPTION
The 74LV377 is a low–voltage CMOS device and is pin and function
compatible with 74HC/HCT377.
The 74LV377 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 (Q
n
) 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.
