DEI1041-SMB-G

The DEI1041 is a BiCMOS device which contains one ARINC 429 differential line receiver. It translates incoming ARINC 429 data bus signals (tri-level RZ bipolar differential modulation) to a pair of TTL/CMOS logic outputs. It meets the requirements of the ARINC 429 Digital Information Transfer Standard. The device is designed to operate in a high noise environment. Inputs are accepted over a ª_20 V common mode voltage range and the receivers provide over 2 V of hysteresis. Circuit speed is optimized to reject high frequency transients.


Features

Functional Description

The DEI1041 is a BiCMOS device which contains one ARINC 429 differential line receiver. It translates incoming ARINC 429 data bus signals (tri-level RZ bipolar differential modulation) to a pair of TTL/CMOS logic outputs. It meets the requirements of the ARINC 429 Digital Information Transfer Standard.

The device is designed to operate in a high noise environment. Inputs are accepted over a 20 V common mode voltage range and the receivers provide over 2 V of hysteresis. Circuit speed is optimized to reject high frequency transients.

All ARINC input pins are designed with internal protection from damage due to transients meeting the lightning induced transient requirements of DO-160 Level 3 pin injection. The ARINC inputs may optionally be connected to ARINC bus through external 10 k
