74LS244 Octal Tri-State Buffer

These 74LS244 family of 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.

I use these all the time for cleaning up noisy data and for line level voltage conversions.
