3.3-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 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.
