产品概述
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 non-inverting 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 SN74LS24x and SN74S24x devices can be used to drive terminated lines down to 133
Ω.
