Input hysteresis and programmable grounds

Input hysteresis provides designers with a tool to minimize external components. Whether using the inputs to create a clock, or reducing the need for external buffers to sharpen up an input signal, CoolRunner-II CPLD inputs provide designers with a flexible and powerful features:

  • Improved noise immunity
  • Reduced power consumption
  • Superior signal integrity
