QP Semi produces a line of military DSCC / DESC approved Interface products based on industry standards from AMD, Philips, Fairchild and National. In addition, QP Semi has reverse engineered a number of interface and logic products including the popular AMD AM26LS31/32/33 family of line driver and receivers, and the National DS1632. The QP Semi 26LS32/33 incorporates a fail-safe feature as in the original AMD version. All products are available in hermetic packages including ceramic DIP, LCC, and Flatpack. All approved products are manufactured by QP Semi using MIL-PRF-38535 or MIL-STD-883 certified die.

QP Semi is a DSCC /DESC QML certified manufacturer of discontinued and obsolete mil spec IC’s.
