Description
DEI1188 is an eight-channel discrete-to-digital interface IC implemented in an HV DIMOS technology.
Features
- 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.
