Description
Edge647
Pin Electronics Driver, Window
Comparator, and Switch Matrix
Applications
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.
The Edge647 is intended to offer an extremely low leakage,
low cost, low power, small footprint, per pin solution for
100 MHz and below pin electronics applications. It is a
higher performance, pin and functionally compatible
version of the Edge646.
