Buffers, Drivers, Receivers, Transceivers FAQ

What is the logic polarity of the SN74HCT244PW?

The device is non-inverting, passing data from the A inputs to the Y outputs without inversion.

How does the output enable control function?

When the output enable (OE) input is low, the device transfers data. When OE is high, the outputs enter a high-impedance state.
