74LS241 DIP Octal Buffer and Line Driver with Non-Inverting 3-State Outputs
The 74LS241 is a high speed TTL integrated circuit designed to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers. This device contains eight independent non-inverting buffers organized into two groups of four. A unique feature of the 74LS241 is the complementary nature of its output-enable inputs: one group is enabled by an active-low signal, while the other is enabled by an active-high signal.
This configuration is specifically intended to facilitate the control of bidirectional data flow or to allow the device to function as a 4-bit multiplexer/demultiplexer. When the respective enable inputs are in their active states, the data is passed directly from the inputs to the outputs without inversion. When disabled, the outputs enter a high-impedance state, allowing multiple devices to share the same bus lines. Its high-current drive capability makes it excellent for driving high-capacitance loads and long transmission lines.
