DescriptionThe 74LVC823A is a high performance, low-power, low-voltage
Si-gate CMOS device and superior to most advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3V or 5.0V devices. In 3-state operation, outputs can handle 5V. This feature allows the use of these devices as translators in a mixed 3.3V/5V environment.
The 74LVC823A is a 9-bit D-type flip-flop with common clock (CP), Clock Enable (CE), Master Reset (MR) and 3-State outputs for bus-oriented applications.
The nine flip-flops will store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW-to-HIGH CP transition provided CE is LOW. When CE is HIGH the flip-flops hold their data.
A LOW on MR resets all flip-flops.
When OE of the 74LVC823A is LOW, the contents of the nine flip-flops is available at the outputs. When OE is HIGH, the outputs go to the high impedance OFF-state. Operation of the OEinput does not affect the state of the flip-flops.
