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
Features
Y TRI-STATE outputs drive bus lines or buffer memory
address registers
Y Outputs sink 64 mA (48 mA mil)
Y 12 mA source current
Y Input clamp diodes limit high-speed termination effects
Y Guaranteed 4000V minimum ESD protection
