74F244 Octal Buffers/Line Drivers with 3-State Outputs IC (74244) DIP-20 Package

The 74F244 is an octal buffer that is ideal for driving bus lines of buffer memory address registers. The outputs are all capable of sinking 64mA and sourcing up to 15mA, producing very good capacitive drive characteristics. The device features two output enables, OEa and OEb, each controlling four of the 3-State outputs. The 74F244 is functionally equivalent to the 74F244. It has been designed to reduce effects of ground noise. Other advantages are noted in the features
