DEI5090-MES-G

The DEI5090 line driver is a CMOS integrated circuit designed to directly drive the ARINC 429 avionics’ serial digital data bus. The device converts TTL/CMOS serial input data to the tri-level RZ bipolar differential modulation format of the ARINC bus. A TTL/CMOS control input selects the output slew rate for HI (100KBS) and LOW (12.5KBS) speed operation. No external timing capacitors are required.

Attributes

Functional Description The DEI5090 line driver is a CMOS integrated circuit designed to directly drive the ARINC 429 avionics’ serial digital data bus. The device converts TTL/CMOS serial input data to the tri-level RZ bipolar differential modulation format of the ARINC bus. A TTL/CMOS control input selects the output slew rate for HI (100KBS) and LOW (12.5KBS) speed operation. No external timing capacitors are required. The part includes a dual polarity voltage doubler, allowing it to operate from a single +3.3V supply using only four external capacitors.
