74ls244芯片资料及功能作用

74ls244芯片资料及功能作用,These buffers/line drivers are designed to improve both the

performance and PC board density of TRI-STATE buffers/

drivers employed as memory-address drivers, clock drivers,

and bus-oriented transmitters/receivers. Featuring 400 mV

of hysteresis at each low current PNP data line input, they

provide improved noise rejecTIon and high fanout outputs

and can be used to drive terminated lines down to 133X.

Features

Y TRI-STATE outputs drive bus lines directly

Y PNP inputs reduce DC loading on bus lines

Y Hysteresis at data inputs improves noise margins
