Buffers, Drivers, Receivers, Transceivers FAQ

How does the bushhold feature work?

The data inputs include active bushold circuitry that holds unused or floating inputs at a valid logic level, eliminating the need for external pull-up or pull-down resistors.

What is the control mechanism for the outputs?

The device is nibble-controlled, meaning each 4-bit section has separate 3-state control inputs. These can be shorted together for full 16-bit operation.
