54LS244 - Octal TRI-STATE Buffers/Line Drivers/Line Receivers

Description

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 impro
