SL74LS244
Octal 3-State Noninverting Buffer/Line
Driver/Line Receiver
These octal buffers and line drivers and designed specifically to
improve both the performance and density of three-state memory
address drivers, clock drivers, and busoriented receivers and
transmitters.
This devise features high fan-out, improved fan-in, and 400 mV noise
margin.
It can be used to drive terminated lines down to 133 ohms.
