DESCRIPTION/ORDERING INFORMATION
This 10-bit buffer/bus driver is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVC828A 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 SN74LVC828A provides inverting 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.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
