The DEI1026 is a six channel discrete-to-digital interface BiCMOS device. It senses six Open/Ground discrete signals of
the type commonly found in avionic systems. The inverted 3-state outputs are TTL/CMOS compatible and are enabled by
the OE and CE pins. The inputs are lightning protected to meet the requirements of DO160 Sec 22 Waveforms 3, 4, and
5, Level 3. See figures 5-7. The device is available in a 16 lead .150 SOIC and .300 Ceramic SOP.
With its reliability, low cost, operating range, and lightning protection, the DEI1026 meets a large variety of interface
requirements for aerospace applications.
