DEI5072-SMS-G
The DEI5x7x family of CMOS integrated circuits are line drivers 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.
Features
- TTL/CMOS TO ARINC 429 Line Driver.
- Rate control input set Hi (100KBS) or Lo (12.5KBS) speed slew rates.
- Operates from ±5V power supply.
- Drives full ARINC load.
- Output resistor options: 7.5, 27.5 or 37.5 Ohms.
- Packages:
- 8L SOIC Exposed Pad (single driver)
- 38L MLPQ (QFN) (dual driver)
Attributes
Functional Description The DEI5x7x family of CMOS integrated circuits are line drivers 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 5070 has internal 37.5 Ohm output resistors, the 5071 has 27.5 Ohm resistors, the 5072 has 7.5 Ohm resistors, and the 5270 has two drivers with all output resistor options. The 27.5 and 7.5 Ohm options require external series resistors which are typically used to implement a transient voltage protection network.
