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 interfa
The NXP 74HC377 and 74HCT377 are octal positive-edge triggered D-type flip-flops featuring clock (CP) and data enable (E) inputs. When the enable input E is LOW, the outputs Qn assume the state of their corresponding Dn inputs upon a LOW-to-HIGH clock transition. The devices include clamp diodes to allow the use of current-limiting resistors for interfacing with voltages in excess of VCC.
