9 Detailed Description

9.1 Overview

The SN74LVC827A provides a high-performance bus interface for wide data paths or buses carrying parity.

The 3-state control gate is a 2-input AND gate with active-low inputs so that, if either output-enable (OE1 or OE2)

input is high, all ten outputs are in the high-impedance state. The SN74LVC827A provides true data at its

outputs.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in

a mixed 3.3-V/5-V system environment.

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

preventing damaging current backflow through the device when it is powered down.
