Listed under the Analog & Data Acquisition category, its primary function is to provide high-current drive capability while presenting a light load to the source, a standard role for octal line drivers in 5V TTL logic systems. ## Active lifecycle and bulk packaging Supplied in Bulk packaging, it is suited for through-hole or socketed assembly in prototyping, rework, or low-to-medium volume production runs where tape-and-reel is not required.","metaTitle":"54LS244FMQB Texas Instruments LS Series Bus Driver, Bulk","metaDescription":"Texas Instruments 54LS244FMQB LS series bus driver with 3-state outputs.
