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.
