DM74LS244 Octal 3-STATE Buffer/Line Driver/Line Receiver
General Description
These buffers/line drivers are designed to improve both the performance and PC board density of 3-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 133Ω.
Features
s 3-STATE outputs drive bus lines directly s
PNP inputs reduce DC loading on bus lines s Hysteresis at data inputs impro...
