3-V or 2.
5-V Logic Inputs • Maximum tpd of 15 ns at 5 V • 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers • PNP Inputs Reduce DC Loading • Hysteresis at Inputs Improves Noise Margins 2 Applications • Servers • LED Displays • Network Switches • Telecom Infrastructure • Motor Drivers • I/O Expanders 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.
