74LS241 Octal Bus/Line Driver Tri-State
Package PDIP, SOIC Series 74LS
74LS241 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. 74LS241 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
