Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the OE inputs?

The device has two symmetrical active-low output-enable (OE) inputs. When an OE input is low, the corresponding four-bit buffer passes inverted data. When high, the outputs enter a high-impedance state.

How does the center-pin configuration benefit the design?

The center-pin VCC and GND configurations are designed to minimize high-speed switching noise, improving signal integrity in dense PCB layouts.
