EDGE HIGH-PERFORMANCE PRODUCTS
Pin Electronics Driver, Window
Comparator, and Switch Matrix
The Edge647 is an integrated trinary driver, window • Low Cost Automatic Test Equipment
comparator, and switch matrix pin electronics solution
manufactured in a wide voltage CMOS process. It is
designed for automatic test equipment and
instrumentation where cost, functional density, and power
are all at a premium.
The tristatable driver is capable of generating 3 levels -
one for a logic high, one for a logic low, and one for either
a termination voltage or a special programming voltage.
The on-board window comparator effectively determines
whether the DUT is in a high, low, or intermediate state. Functional Block Diagram
The switches are included to allow such functions as PMU,
pull up, and pull down connections.
