AI Contract Overview

The United States Navy, through the NSWC Indian Head Division, is seeking potential suppliers for the SP332ET-L integrated circuit, a multiprotocol transceiver manufactured by MaxLinear, Inc. This device supports both RS-232 and RS-485 communication protocols with four drivers and four receivers for RS-232 and two drivers and two receivers for RS-485, all housed in a 28-pin WSOIC package. It operates solely on a 5V power supply using a patented charge pump and includes a loopback function for internal self-testing. The part is designated as obsolete or end-of-life, meaning the Navy is searching for alternative sources to support existing systems, as the original manufacturer no longer produces it. All responses must include company details such as name, address, point of contact, business size, taxpayer identification number, DUNS/SAM number, CAGE Code, and a summary of the company’s capabilities to supply this component or a suitable replacement. This notice is a market survey, not a formal request for proposals or a commitment to procure, and the government retains full discretion to pursue or cancel any future acquisition. Responses are due by May 26, 2026, and must be submitted without cost or obligation to the U.S. Government. The solicitation number is N00174-26-SS-0001 under NAICS code 334413 for semiconductor and related device manufacturing. Information may be submitted to the primary point of contact, Lawrence J. Connell, and secondary contact, Tammy Kershner, at the specified Navy email addresses. The government will not provide feedback on submissions nor guarantee a follow-on solicitation, though any future procurement will be publicly announced through official channels.
