3 Description

The SNx4LS24x, SNx4S24x 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 outputcontrol

(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

SN74LS24x and SN74S24x devices can be used to

drive terminated lines down to 133 Ω.
