OCTAL THREE-STATE BUFFER/LATCH
This series of devices combines four features usually found
desirable in bus-oriented systems: 1) High impedance logic inputs
insure that these devices do not seriously load the
bus; 2) Three-state logic configuration allows buffers not being
utilized to be effectively removed from the bus; 3) Schottky
technology allows for high-speed operation; 4) 48 mA drive
capability.
