DEI1166-TMS-G

The DEI1166 is an eight-channel parallel-output 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.


Features

  • Eight GND/OPEN discrete inputs
  • Internal pull up resistor with 1mA source current to prevent dry relay contacts
  • Internal isolation diode
  • Inputs protected from Lightning Induced Transients per DO160, Section 22 Level 3 pin injection
  • Hysteresis provides noise immunity
  • 3.3 V or 5 V TTL/CMOS compatible digital IO
  • 8 tri-state outputs
  • /CE & /OE control inputs
  • VCC Logic Supply: 3.3 V or 5 V
  • VDD Analog Supply: 5 V to 18 V
  • 24L TSSOP package
