74HCT245 Overview
The SNx4HCT245 octal bus transceivers are designed for asynchronous two-way munication between data buses. The controlfunction implementation minimizes external timing requirements. The SNx4HCT245 devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the directioncontrol (DIR) input.
