DESCRIPTION
The HI-8444 and HI-8445 are quad ARINC 429 line receiver ICs available in a 20-pin TSSOP package. The HI-8448 contains 8 independent ARINC 429 line receivers. The technology is analog / digital CMOS. The device is designed to operate from either a 5V or 3.3V supply. Each receiver channel translates incoming ARINC 429 data bus signals to a pair of TTL/ CMOS outputs.
FEATURES
• Direct ARINC 429 quad or octal line receivers in small footprint packages
• 3.3V or 5.0V single supply operation
• Test inputs bypass analog inputs and force digital outputs to a one, zero, or null state
• ARINC inputs are internally lightning protected per DO-160G level 3 (-10 configuration only)
• Hi-Rel processing options available
