DEI1024-G
The ARINC 429 Line Driver Circuit is a bipolar monolithic IC designed to meet the requirements of several general aviation serial data bus standards. These include the differential bipolar RZ types such as ARINC 429, ARINC 571, and ARINC 575. The DEI1022, DEI1023, DEI1024, and DEI1025 are a family of ARINC Line Driver circuits with variations in driver output resistance and output fusing.

Attributes
Functional Description: The ARINC 429 Line Driver Circuit is a bipolar monolithic IC designed to meet the requirements of several general aviation serial data bus standards. These include the differential bipolar RZ types such as ARINC 429, ARINC 571, and ARINC 575.
The DEI1022, DEI1023, DEI1024, and DEI1025 are a family of ARINC Line Driver circuits with variations in driver output resistance and output fusing.
Serial data is presented on DATA(A) and DATA(B) logic inputs in the dual rail format of the DEI1016. The driver is enabled by the SYNC and CLOCK inputs. The output voltage level is programmed by the VREF input and is normally tied to +5VDC along with V1 to produce output levels of +5 volts, 0 volts, and -5 volts on each output for ±10 volt differential outputs.
The driver output resistance of the DEI1022 and DEI1023 is 75Ω at room temperature; 37.5Ω on each output. The driver output resistance of the DEI1024 and the DEI1025 is zero. The output slew rate is controlled by external timing capacitors on CA and CB. Typical values are 75pF for 100KHz and 500pF for 12.5KHz data.
