QP Semiconductor Announces Qualified Replacements for DS1691AJ - AM26LS30 (SMD Device).

QP Engineering Team Redesigns and Reengineers SMD Replacement Parts

SANTA CLARA, Calif. -- QP Semiconductor today announced that the Defense Supply Center, Columbus (DSCC) has approved the company's newly reengineered and redesigned version of the discontinued RS 422, RS 423 Line Drivers with TRI-STATE([R]) Outputs; part numbers DS1691AJ/883, DS1691AJ and AM26LS30/BEA (5962-8672101EA).

"This is a strong addition to our growing list of redesigned and remanufactured replacement parts, particularly for many manufacturers facing supply issues today," said John Stannard, president of QP Semiconductor. He adds, "This part proved challenging to redesign but ultimately we partnered with a suitable wafer manufacturing facility with the necessary processes to support the specs of this unique line driver."

Particularly for various equipment requiring a data interface protocol, QP Semiconductor is offering this fully qualified replacement DS1691/AM26LS30 device just as the present supply dwindles into obsolescence. "We are pleased to offer our customers assurance of a reliable, available, and long term source of qualified parts," said Jim Townsend, marketing director.

These low power Schottky TTL line drivers are designed to meet the requirements of EIA standards RS-422 and RS-423. They feature 4 buffered outputs with high source and sink current capability with internal short circuit protection. The device may be selected via a mode control pin for operation either as 4 single-ended line drivers or 2 differential line drivers.
