BD429/BD429A/BD429B/BD429C
ARINC 429/RS-422 Line Driver
Integrated Circuit
www.DataSFheeeta4Utu.cormes:
• ARINC 429 Line Driver for HI speed (100 kHz) and LOW speed (12.5 kHz) data rates
• Pin for Pin replacement part for industry standard ARINC 429 Line Drivers
• Available in a 16 Pin SOIC (WB), 16 Pin CERDIP, 16 Pin Plastic Dip,
16 Lead Ceramic SOP, 28L CLCC and 28L PLCC
• Low EMI RS-422 line driver mode for data rates up to 100 kHz
• Adjustable slew rates via two external capacitors
• Inputs are TTL and CMOS compatible
• Low quiescent power of 125mW (typical)
• Programmable output differential range via VREF pin
• Outputs are fused for failsafe overvoltage protection
• Drives full ARINC load of 400Ω and 30,000pF
• Extended (-55°C/+85°C) and Military (-55°C/+125°C) temperature ranges
• 100% Final Testing
