TECHNICAL DATA
IN74LS244
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. • 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers • P-N-P Inputs Reduce D-C Loading • Hysteresis at Inputs Improves Noise Margins
