SN74LS244N, Восемь буферных элементов с тремя состояниями на …The SN74LS244N is an Octal Buffer and Line Driver with 3-state outputs. This is designed specifically to improve both the performance and density of three-state memory address driver, clock driver and bus-oriented receivers and transmitters. The designer has a choice of selected combinations of inverting and non-inverting outputs and symmetrical, active-low output-control (G)inputs and complementary output-control (G and G) inputs. This device features high fan-out, improved fan-in and 400mV noise margin. The SN74LS device can be used to drive terminated lines down to 133R., PNP inputs reduce DC loading, Hysteresis at inputs improves noise margins, Green product and no Sb/Br
