FAQ

How are the 16 bits organized within the device?

The device is organized as four independent 4-bit low-impedance switches, each with its own separate output-enable (OE) input.

What determines the direction of data flow?

Data can flow bidirectionally from port A to port B, or vice versa, when the respective OE input is low.
