The U.S. Navy is seeking suppliers for an obsolete, end-of-life IC transceiver (Part Number SP332ET-L) that combines RS-232 and RS-485 functions in a 28-pin WSOIC package. This is a sources sought notice, not a request for proposals, and the government will consider all responses but may choose not to compete the requirement. No specific budget amount or performance location is mentioned in the notice. Interested parties must submit their organization details, business size, and a summary of capabilities. No bid or submission deadlines are provided, as this is a market survey to gauge interest.
