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 VCC.
