DEI3283-SAB-G

The DEI3283 consists of two analog ARINC 429 receivers which take differentially encoded ARINC level data and convert it to serial TTL level data. The DEI3283 provides two complete analog ARINC receivers with no external components required. Input level shifting thin film resistors and bipolar technology allow ARINC input voltage transients up to ª_200 V without damage to the DEI3283. Each channel is identical, featuring symmetrical propagation delays for better high-speed performance. Input common mode rejection is excellent and threshold voltage is stable, independent of supply voltage. Data outputs are TTL and CMOS compatible. Two TTL compatible test inputs used to test the ARINC channels are available. They can be used to override the ARINC input data and set the channel outputs to a known state. The DEI ARINC line driver family ICô__s are companion chips to the DEI3283 line receiver. Together they provide the analog functions needed for the ARINC 429 interface.

Functional Description

The DEI3283 contains two discrete ARINC 429 receiver channels. Each channel contains three main sections: an input signal conditioning network, a window comparator, and a logic output buffer stage. A test function is common to both channels.

The input network comprises resistors and current switching circuits. It conditions the ARINC inputs with overvoltage protection, test signal injection, and biasing suitable for the comparators. The network provides excellent input common mode rejection.

The window comparators detect ARINC pulse transitions in the signals from the input network. An ARINC input
