HD74LS244P Datasheet

Buffer e line driver


These octal buffers and line drivers are designedspecifically to improve both the performance anddensity of three-state memory address drivers,clock drivers, and bus-oriented receivers andtransmitters. The designer has a choice ofselected combinations of inverting andnoninverting outputs, symmetrical, active-lowoutput-control (G) inputs, and complementaryoutput-control (G and G) inputs. These devicesfeature high fan-out, improved fan-in, and 400-mVnoise margin. The HD74LS244P and SN74S’ devicescan be used to drive terminated lines down to133 Ω. HD74LS244P Features • 3-State Outputs Drive Bus Lines or BufferMemory Address Registers• PNP Inputs Reduce DC Loading• Hysteresis at Inputs Improves NoiseMargins
