Datasheet

1. General description
The 74HC377; 74HCT377 is an octal positive-edge triggered D-type flip-flop. The device
features clock (CP) and data enable (E
) inputs. When E is LOW, the outputs Qn assume
the state of their corresponding Dn inputs that meet the set-up and hold time requirements
on the LOW-to-HIGH clock (CP) transition. Input E
must be stable one set-up time prior to
the LOW-to-HIGH transition for predictable operation. Inputs include clamp diodes that
enable the use of current limiting resistors to interface inputs to voltages in excess of V
CC
.
