Mitel Semiconductor products are identified by a prefix defining the product family, a device type designation number, a specification suffix, and a package suffix. The family prefix consists of two alphabetic characters that denote the family of products in general and general terms. The device type is a four- to five-digit alphanumeric number that identifies the product within the family.
The specification suffix defines variants of a particular device type and their importance is described in the datasheet of the device in question. The package suffix, which defines the package type, refers to the drawings in the data table section "Package schemas". The first page of each data sheet contains a section called "Order Information". This shows the complete part number for each of the variants and package styles available for the device and must be consulted to determine the correct part number for ordering purposes.
