SN74LS244DWR

八路缓冲器并用3态输出线路驱动器 OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS

The is an octal Buffer/Line Driver designed specifically to improve both the performance and density of three-state memory address drivers, clock drivers and bus-oriented receivers and transmitters. The designer has a choice of selected combinations of inverting and non-inverting outputs, 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.
