DEI1198 8通道GND/OPEN并联输出离散接口IC
DEI1198
  • Eight discrete inputs
  • Senses GND/OPEN discrete signals.
  • Meets input threshold and hysteresis requirements specified per AirBus ABD0100H specification.
  • Thresholds: 4.5 V / 10.5 V, Hysteresis: 3 V
  • ~1 mA DIN source/sink current to prevent dry relay contacts.
  • Internal isolation diode.
  • Uses an external 3 kô_Õ resistor on the inputs to implement lightning transient immunity of 1600 V and higher. i.e.: DO160E, Section 22, Levels 4 and 5.
  • Inputs protected from Lightning Induced Transients per DO160, Section 22, Cat A3 and B3 plus waveform 5A to 500 V.
  • Parallel I/O interface
  • TTL/CMOS compatible inputs and Tristate outputs
  • CLK & /OE control inputs and outputs
  • Logic Supply Voltage (VCC): 3.3 V °%
  • Analog Supply Voltage (VDD): 12.0 V to 16.5 V
  • Package Options
  • 24 Lead TSSOP
  • Pin compatible with DEI1166/67
