This device together with associated resistors meets the I/P requirements of ARINC 429 specification for 4 independent channels of input. It consists of 4 pairs of Norton type CMOS comparators with a common current mirror threshold circuit set by a single external resistor.

• Converts received ARINC 429 data levels to 2 line CMOS compatible levels
• Adjustable threshold using 1 resistor
• Single 5V supply with low power consumption < 50mW
• Full MIL operating range
• Reduces system package count.
• Can be used as ARINC 429, 561, 568, 575, or Tacan interface
