Each HD74HC245 has an active low enable input G and a direction control input, DIR. When DIR is high, data flows from the A inputs to the B outputs. When DIR is low, data flows from the B inputs to the A outputs. The HD74HC245 transfers true data from one bus to the other. This device does not have schmitt trigger inputs.
