Buffers, Drivers, Receivers, Transceivers FAQ

What is the logic polarity of the SN74HCT240N?

The SN74HCT240N is an inverting buffer, meaning the output state is the logical complement of the input state.

Does the SN74HCT240N support bidirectional data flow?

No, the SN74HCT240N is unidirectional. For bidirectional applications, the SN74HCT244 or SN74HCT125 might be considered depending on the specific control requirements.
