PRELIMINARY
Revision 1/ June 13, 2000
The Edge672 is a monolithic ATE pin electronics
comparator and load solution manufactured in a high-
performance complementar y bipolar process. In
automatic test equipment, the Edge672 incorporates a
dynamic load and window comparator suitable for very
fast, bidirectional channels in Memory, VLSI, and Mixed-
Signal test systems.
The three-statable load is capable of sourcing and sinking
35 mA over an 11V common mode range. Source and
sink currents are independently programmable. The load
is configurable to support a clamping function, a
ter mination
function, plus
any
custom
load
configurations.
The comparator is capable of tracking very fast edges
and passing sub-ns pulses over a 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 inclusion of a high performance load and comparator
in a 32 pin TQFP (7 mm X 7 mm) package offers a
highly integrated solution traditionally implemented with
multiple integrated circuits or discrete components.
