DEI1160A-SMS

The DEI1160A is an eight-channel discrete-to-digital interface IC implemented in an HV DMOS technology. It senses eight discrete signals of the type commonly found in avionic systems and converts them to serial logic data. Each input can be individually configured as either GND/OPEN or 28V/OPEN format input via a serial data input command. The discrete 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

  • The DEI1160A is an improved version of the DEI1160 with greater transient voltage immunity, which simplifies the equipment design for lightning and RF immunity requirements.
  • Eight discrete inputs
  • Individually configurable to sense either GND/OPEN or 28V/OPEN(or 28V/GND) discrete signals
  • Hysteresis provides noise immunity
  • 1mA input current to prevent dry relay contacts.
  • Internal isolation diode
  • Inputs protected from Lightning Induced Transients per DO160E, Section 22, Cat A3 and B3.
  • Inputs protected from Power Input Abnormal Surge per DO160E, Section 16, Cat Z.
  • Serial I/O interface to read data register and write configuration register
  • Direct interface to Serial Peripheral Interface (SPI) port.
  • TTL/CMOS compatible inputs and Tristate output
  • 10MHz Data Rate
  • Serial input to expand Shift Register
