Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle power-up conditions?

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

What is the input voltage tolerance?

Inputs accept voltages up to 5.5V, allowing the device to be driven by either 3.3V or 5V devices.
