The device features an Output Enable (OE) input for easy cascading and Transmit/Receive (T/R) input for direction control. The 3-State outputs, B0-B7, have been designed to prevent output bus loading if the power is removed from the device. The 30 Ohm series termination on the outputs reduces over/undershoot making them ideal for driving DRAM.
