1. General description

The 74LVC273 is an octal positive-edge triggered D-type flip-flop. The device features clock (CP)

and master reset (MR) inputs. 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. A LOW

on MR forces the outputs LOW independently of clock and data inputs. 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.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
