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

DEI1188 is an eight-channel discrete-to-digital interface IC implemented in an HV DIMOS technology. It senses eight GND/OPEN discrete signals of the type commonly found in avionic systems and converts them to serial logic data. The discrete data is read from the device via an eight-bit serial shift .

DEI1188 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 Use
