FUNCTIONAL DESCRIPTION
The DEI1148 is a BiCMOS device which contains eight differential line receivers. Each receiver channel translates
incoming ARINC 429 data bus signals (tri-level RZ bipolar differential modulation) to a pair of TTL/CMOS logic
outputs. Each channel operates independently and meets the requirements of the ARINC 429 Digital Information
Transfer Standard. Refer to Figure 2 DEI1148 Block Diagram and Truth Table.
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 Volts of hysteresis. Circuit speed is optimized to reject high
frequency transients.
The DEI1148 device provides logic level TEST inputs for built in system test. There are two TEST input ports, each
force the outputs of four receivers to the specified ZERO, ONE or NULL state. The ARINC inputs are ignored when
the device is in test mode.
The ARINC inputs incorporate on-chip lightning protection by use of high value resistors on the inputs to minimize
IR heating. The resistors have dielectric isolation to withstand the voltage transients. The inputs withstand lightning
induced transients up to and including DO160 Level 3 pin injection levels. Higher levels can be achieved with the
addition of external TVS devices between the inputs and VSS, or alternately, TVS devices in combination with series
current limiting resistors between the ARINC bus and the IC/TVS node. The series resistors reduce the power
requirement and size of the TVS. Resistor values up to 10K ohms are feasible.
The ARINC inputs withstand inadvertent short to 115 Vac aircraft power without sustaining damage.

Notes:
1. Stresses above these limits can cause permanent damage.
2. Per DO160, Sect 22 Level 3 pin injection. See Figures 5 – 7.
3. Inputs can be protected to withstand higher stress by adding series resistors and shunt TVS on inputs. Inputs
withstand 1500 V Waveform 5A when clipped ≤ 600 V.
