GTL & ECL Terminators-Series 752 & 753
High Speed Digital Termination Networks
• Low inductance leadless construction
• Excellent high frequency response
• Very low crosstalk
• High power dissipation versus board space
• Spice models available for circuit simulation
• Solder-coated nickel barrier pads
• Tape & reel packaging per EIA 481
• Designed to work with standard automated
surface mount pick & place solder processes
Resistance Tolerance:
Standard ±2% or 0.5Ω (whichever is greater)
Special: ±1%
Temperature Coefficient (TCR):
Standard: ±200PPM/°C
Operating Temperature Range:
-55°C to +125°C
See pages 16-19 for physical dimensions, power rating and
other 752 & 753 information.
