1. General description
The 74LVC823A is a 9-bit D-type flip-flop with common clock (pin CP), clock enable (pin CE),
master reset (pin MR) and 3-state outputs (pins Qn) for bus-oriented applications. The 9 flip-flops
stores the state of their individual D-inputs that meet the set-up and hold times requirements on the
LOW to HIGH CP transition, provided pin CE is LOW. When pin CE is HIGH, the flip-flops hold their
data. A LOW on pin MR resets all flip-flops. When pin OE is LOW, the contents of the 9 flip-flops
are available at the outputs. When pin OE is HIGH, the outputs go to the high-impedance
OFF-state. Operation of the OE input does not affect the state of the flip-flops.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied
to the outputs. These features allow the use of these devices as translators in mixed 3.3 V and 5 V
applications.
