DEI1067-SES-G

The DEI1067-SES-G 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 an eight-bit serial shift register with 3-state output. This serial interface is compatible with the industry standard Serial Peripheral Interface (SPI) bus.


Features

  • Eight GND/OPEN discrete inputs
    • Meets electrical requirements for ARINC 735A GND/OPEN discrete inputs
    • 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 DO160, Section 22, Level 3 pin injection
  • 3-wire serial interface (/CS, CLK, DOUT)
    • Direct interface to Serial Peripheral Interface (SPI) port.
    • TTL/CMOS compatible inputs and Tristate output
    • 10 MHZ Data Rate
    • Serial input to expand Shift Register
  • Logic Supply Voltage (VCC): 3.3 V or 5 V
  • Analog Supply Voltage (VDD): 15 V ±10%
  • Pin compatible with DEI1066
  • 16L NB SOIC package
