Product Summary
The HD74HC245P is an octal bus transceiver with 3-state outputs. The HD74HC245P 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 HD74HC245P transfers true data from one bus to the other. The HD74HC245P does not have schmitt trigger inputs.
