Buffers, Drivers, Receivers, Transceivers FAQ

How are the outputs controlled?

The device contains two independent 4-bit buffers, each with a separate output-enable (OE) input. When OE is low, data passes non-inverted; when high, outputs enter a high-impedance state.

What is the recommended handling for unused inputs?

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