Descritpion

This IC senses a high voltage input and produces an output at TTL logic levels. When an input signal becomes active, its output is converted to a logic level to signal another device or circuit. The 74LS244 also features reverse voltage protection on the output buffer, protecting the underlying devices in the event of reverse voltage.

These octal buffers and line drivers are designed specifically to improve both the performance and density of three-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The designer has a choice of selected combinations of inverting and noninverting outputs, symmetrical, active-low output-control (G)\ inputs, and complementary output-control (G and G\) inputs. These devices feature high fan-out, improved fan-in, and 400-mV noise margin. The SN74LS’ and SN74S’ devices can be used to drive terminated lines down to 133Ω .
