Overview
The 74HC377D,653 is an octal positive-edge triggered D-type flip-flop produced by Nexperia USA Inc. This integrated circuit is part of the 74HC family, known for its high-speed CMOS logic. The device features eight D-type flip-flops with a common clock (CP) and data enable (E) inputs. When the data enable input (E) is LOW, the outputs (Qn) assume the state of their corresponding Dn inputs, provided the set-up and hold time requirements are met on the LOW-to-HIGH clock transition. This component is widely used in various electronic designs due to its robust features and versatility.
