Buffers, Drivers, Receivers, Transceivers FAQ

How are unused inputs handled?

Unused inputs must be terminated at VCC or GND to ensure proper operation. Floating inputs can cause excessive power consumption and oscillations.

What is the function of the OE pins?

Each OE pin controls four buffers. When low, outputs are enabled; when high, outputs enter a high-impedance state.
