description
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鈥?and SN74S鈥?devices
can be used to drive terminated lines down to
