Description

The 74LS244 Octal Tri-State Buffer is a 8-channel, 4.75 V to 5.25 V bipolar buffer with 3-state outputs.

It is designed to boost both the performance and density of three-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Feature high fan-out, improved fan-in, and 400-mV noise margin.

The designer has choices of selected combinations;

  • inverting and non-inverting outputs
  • symmetrical
  • active-low output-control (G) inputs
  • complementary output-control (G and G) inputs

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
  • PNP Inputs Reduce DC Loading
  • 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
  • Hysteresis at Inputs Improves Noise Margins
