The IA6805E2 is a "plug-and-play" drop-in replacement for the original IC. Innovasic produces replacement
ICs using its MILESTM, or Managed IC Lifetime Extension System, cloning technology. This technology
produces replacement ICs far more complex than "emulation" while ensuring they are compatible with the
original IC. MILESTM captures the design of a clone so it can be produced even as silicon technology
advances. MILESTM also verifies the clone against the original IC so that even the "undocumented features"
are duplicated. This data sheet documents all necessary engineering information about the IA6805E2
including functional and I/O descriptions, electrical characteristics, and applicable timing.
