DEI1188 - 8CH GND/OPEN DISCRETE INTERFACE IC W/ EXT HV PROTECTION

Datasheet Details

DEI1188 is an eight-channel discrete-to-digital interface IC implemented in an HV.

Eight discrete inputs o Senses GND/OPEN discrete signals. o Meet input threshold and hysteresis requirements specified per AirBus ABD0100H specification.
Thresholds: 4.5V/10.5V, Hysteresis: 3V o 1mA input current to prevent dry relay contacts. o Internal isolation diode. o Uses external series 3Kohm resistors on inputs to implement lightning transient immunity of 1600V and higher. i. e. : DO160E, Section 22, Levels 4 and 5. o Inputs protected from Lightning Induced Transie.
