Buffers, Drivers, Receivers, Transceivers FAQ

How does the dual enable function work?

Simultaneous enabling of OEAB and OEBA inputs configures the transceiver to store data. Each output reinforces its input, maintaining the last state on both bus sets when other sources are in a high-impedance OFF-state.

What is the purpose of the power-up 3-state feature?

The power-up 3-state feature ensures that the outputs enter a high-impedance state during power-up, preventing unintended signal driving until the device is fully operational and enabled.
