(((Joel Altman remarks: We deal with a company called 'The Trailing Edge of Technology.')))


"From its beginning, Lansdale Semiconductor, Inc., has specialized in 'Aftermarket Technology.' Lansdale has the technical expertise to support the aftermarket and has dedicated itself to that goal, assuring its customer base that older technology products will continue to be available.

"The U.S. Military and Department of Defense contractors make a large portion of Lansdale's clientele. Lansdale helps maintain the integrity of a number of military programs by supplying essential parts which are the equivalent to the originals, avoiding costly redesigns and emulations.

"As technology advances, Lansdale is also keeping an eye on the future. As product life cycles become shorter, more programs are placed at risk by obsolete parts. Lansdale serves two vital functions by purchasing discontinued product lines. It allows the original manufacturer to divest itself of a product it can no longer support. It also offers users of that product the opportunity to keep their programs intact without costly redesign.

"As long as customers need to maintain older systems, Lansdale will be there to supply the technology critical to their success.


"Lansdale was founded in 1964 when Edward Pincus purchased Philco-Ford's small signal transistor line. In 1976, Lansdale acquired Motorola's Germanium transistor line. The company moved from Lansdale, Pennsylvania, to Arizona that same year.

"Through the following years, the company purchased additional product lines, including the first bipolar digital integrated circuit line from Raytheon, and SUHL, DTL, and TTL lines from Motorola and Signetics. A bipolar wafer fabrication facility in Santa Monica, California, was added in 1984, allowing the company to expand its manufacturing capability in standard and custom integrated circuits. In 1986, the Germanium transistor lines were sold, and Lansdale dedicated itself to producing integrated circuits.

"In 1987, Lansdale was purchased by then-company president R. Dale Lillard. Since then, Lansdale has added product from AMD, Fairchild, Harris, and Intel to the lines it supports. The company expanded its support of Motorola products by acquiring DTL, HTL, Linear, RTL, and more TTL lines in 1991. It has also increased its Signetics offerings by acquiring over 600 new parts, including both military and commercial product in 1992. The new sole-sourced commercial product facilitated Lansdale's expansion into plastic packaging and the commercial marketplace.

"To improve its ability to support its customers, Lansdale built a new wafer fabrication facility in Tempe, Arizona, in 1994, became a QPL manufacturer, then transitioned to QML in 1996. The QML plan was modified to allow Lansdale to list all its products, whether the die was fabricated by Lansdale or the original manufacturer."

(((Joel Altman remarks: Looking through the Lansdale catalog is a trip down Memory Lane for this correspondent. It is interesting to see which circuits Lansdale considers "important." They live up to their mission statement: To manufacture "important" integrated circuits forever.)))
