Catalyst Semiconductor, Inc. Component Intelligence

The master record identifies Catalyst with analog, mixed-signal and non-volatile memory products. In catalog data, engineers may also encounter onsemi-era records under the Catalyst hub, so the current datasheet and manufacturer attribution should be checked for each MPN.

PartGenie provides a complete searchable manufacturer part catalog when source catalog data is available; this hub is the intelligence and navigation layer for understanding Catalyst product families, onsemi integration, lifecycle risk, and sourcing decisions.

Sometimes, but replacement must be qualified at the part level. Compare package, pinout, electrical limits, memory organization, timing, programming behavior, and environmental ratings before treating any onsemi, Texas Instruments, or Infineon device as an alternative.

Because Catalyst content was integrated into onsemi and catalog sources can contain post-acquisition or cross-mapped records. Use the MPN, datasheet source, and current onsemi product page to confirm whether the device is a Catalyst legacy item or an onsemi-family product.
