The SN74LS244DWR 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.
PNP Inputs reduce DC loading
Hysteresis at inputs improves noise margin
3-state Outputs drive bus lines or buffer memory address registers
