Buffers, Drivers, Receivers, Transceivers FAQ

How are the outputs controlled?

Each bank of four outputs has a separate output-enable (OE) input. When OE is low, the outputs pass non-inverted data; when OE is high, the outputs enter a high-impedance state.

What happens if CMOS inputs are left floating?

Standard CMOS inputs must not be left floating. Unused inputs should be terminated at VCC or GND to prevent excessive power consumption and potential oscillations.
