Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial-power-down scenarios?

The device utilizes Ioff circuitry which automatically disables the outputs when powered down. This prevents damaging current backflow through the device when VCC is zero.

What is the function of the Output Enable (OE) pin?

The OE input disables the device, effectively isolating the buses. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor.
