Aeroflex Circuit Technology MT72038 Datasheet

MT72038

FOUR CHANNEL ARINC 429 LINE RECEIVER

• 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
