DD-03296

DD-03296 96-CHANNEL DISCRETE-TO-DIGITAL INTERFACE FEATURES DESCRIPTION The DD-03296 device is a 96-channel discrete-to-digital interface with universal HlRF-isolated inputs that accept 28 V/Open, Open/Gnd and 28 www.DataSheet4U.com V/Gnd signals. The output is an addressable 8- or 16-bit tri-state port, selectable for channel data, status, bounce, built-in self-test (BIST) and major fault, and is compatible with TTL logic. APPLICATIONS The DD-03296 is specifically designed to address built-in self-test autonomy, fault isolation and tolerance. Because of its high reliability and low cost, these features enable the DD03296 to satisfy a variety of interface requirements in aerospace applications, including flight critical, essential, and nonessential functions.
