DEI1166 DEI1166
Octal GND/OPEN Input, Parallel Output Interface IC


The DEI1166 is an eight-channel discrete-to digital interface BiCMOS device. It senses eight Ground/Open discrete signals of the type commonly found in avionic systems. The data is read from the device via a parallel 3-state output.


  • Eight GND/OPEN discrete inputs
    • Meets electrical requirements for ABD0100 GND/OPEN discrete input.
    • Hysteresis provides noise immunity
    • Internal pull up resistor with 1mA source current to prevent dry relay contacts.
    • Internal isolation diode
    • Inputs protected from Lightning Induced Transients per DO160D, Section 22, Cat A3 and B3.
  • 3.3V or 5V TTL/CMOS compatible digital IO
    • 8 tri-state outputs
    • /CS & /OE control inputs
  • Logic Supply : 3.3V and 5 V
  • Analog Supply : 5 to 18 V
  • 24L TSSOP Package
