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’ and SN74S’ devices

can be used to drive terminated lines down to

133 Ω.
