74ls244芯片资料及功能作用,These buffers/line drivers are designed to improve both theperformance and PC board density of TRI-STATE buffers/drivers employed as memory-address drivers, clock drivers,and bus-oriented transmitters/receivers. Featuring 400 mVof hysteresis at each low current PNP data line input, theyprovide improved noise rejecTIon and high fanout outputsand can be used to drive terminated lines down to 133X.FeaturesY TRI-STATE outputs drive bus lines directlyY PNP inputs reduce DC loading on bus linesY Hysteresis at data inputs improves noise margins
