Buffers, Drivers, Receivers, Transceivers FAQ

How does the Schmitt-trigger input benefit signal processing?

It provides hysteresis, making the device tolerant to slow or noisy input signals by preventing multiple transitions caused by noise near the threshold.

What happens to the output when the OE pin is Low?

The outputs enter a high-impedance state, effectively disconnecting them from the circuit regardless of the input state.
