Six-channel discrete-to-digital avionics interface features lightning protection

Keywords: DDC, Avionics

DDC's new DD-O3206VP six-channel discrete-to-digital interface translates discrete avionics signals to TTL levels and is believed to be the smallest such device available with built-in lightning protection.

Discrete interfaces are used in avionics systems to accomplish intelligent switching, relaying, or indicator monitoring. While translating these signals to TTL levels that are compatible with digital avionics may seem simple, lightening protection, small size, and low cost are complicating factors. The new DD-03206VP claims to meets these challenges.

The DD-03206VP is a small, TTL-compatible unit measuring only 9.8mm x 5.8mm width with a 1.35mm profile height. It is thought ideal for use by airframe and avionics systems manufacturers.

The packaging of the device conforms to JEDEC MS-012AC standards for 16-pin SOICs (Small Outline Integrated Circuit) but is actually narrower than traditional designs.

The DD-03206VP is lightning protected to 600V/24A, level 3 of DO160D. The inputs are capable of handling Open/Ground signals while the outputs may be enabled and are TTL-compatible. The devices operate from -55úC to +85úC.

An important addition to DDC's family of discrete interfaces, the DD-03206VP is aimed at aircraft designs where space is always at a premium. With high reliability and low cost, the device is suited to a variety of aerospace applications including flight critical, essential and non-essential functions.
