Buffers, Drivers, Receivers, Transceivers FAQ

What is the logic function of the output-enable controls?

The 3-state control gate consists of two active-low inputs (OE1 and OE2). If either input is high, all eight outputs enter the high-impedance state.

How does the device behave during power transitions?

When VCC is between 0 and 2.1 V, the device remains in a high-impedance state during power-up or power-down to prevent bus contention.
