Overview
The 74HC377D,652 is an octal positive-edge triggered D-type flip-flop produced by Nexperia USA Inc. This integrated circuit is part of the 74HC and 74HCT family, known for their high noise immunity and low power dissipation. The device features clock (CP) and data enable (E) inputs, allowing for precise control over the flip-flop operations. 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.
