General Description
The ’F240, ’F241and ’F244are octal buffersandline driv-
ers designedtobe employedas memoryand address driv-
ers, clock drivers and bus-oriented transmitters/receivers
which provide improvedPCand board density.
Features TRI-STATE outputs drive bus linesor buffer memory
address registers Outputs sink64mA(48mAmil)12mA source current Input clamp diodes limit high-speed termination effects Guaranteed 4000V minimum ESD protection
