Характеристики
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
