1. General description

The 74LVC377 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 will assume the state of their

corresponding D 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 can be driven from either 3.3 V or 5 V devices. This feature allows

the use of these devices as translators in mixed 3.3 V and 5 V environments.
