Edge670
500 MHz
Window Comparator
HIGH-PERFORMANCE PRODUCTS 鈥?ATE
Description
The Edge670 is a monolithic ATE pin electronics
comparator manufactured in a high-performance
complementary bipolar process. In automatic test
equipment, the Edge670 offers a window comparator
suitable for very fast, bidirectional channels in Memory,
VLSI, and Mixed-Signal test systems.
The 670 is capable of tracking very fast edges and
passing sub-ns pulses over an 11V common mode range
while maintaining excellent timing accuracy. The
differential digital outputs are adjustable to
accommodate ECL levels, PECL levels, or custom levels
to interface directly with a CMOS ASIC.
The Edge670 is pin compatible with the Edge672, except
no load is present.
