54F 74F240 54F 74F241 54F 74F244
Octal Buffers Line Drivers with TRI-STATE Outputs
General Description
The ’F240 ’F241 and ’F244 are octal buffers and line driv-
ers designed to be employed as memory and address driv-
ers clock drivers and bus-oriented transmitters receivers
which provide improved PC and board density
