Octal Buffers And Line Drivers With 3-State Outputs - SN74LS244
Datasheet
SNx4LS24x, SNx4S24x Octal Buffers and Line Drivers With 3-State Outputs datasheet (Rev. D)
 

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.

Features

  • Inputs Tolerant Down to 2 V, Compatible With 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
