Buffers, Drivers, Receivers, Transceivers FAQ

What is the logic polarity of the SN74BCT540ANSR?

The device provides inverting logic, meaning the output state is the complement of the input state.

How does the three-state control function?

The outputs enter a high-impedance state when the output-enable inputs are asserted high, disconnecting them from the bus.
