74LS541 Octal Buffer/Line Driver Tri-State
Package SOIC Series 74LS
74LS541 overview
The 74LS series of integrated circuits (ICs) was one of the most popular logic families of transistor-transistor logic (TTL) logic chips. 74LS series is a bipolar, low-power Schottky IC. 74LS541 is octal buffers and line drivers with the same functions as the LS240 and LS241, but with pinouts on the opposite side of the package.
