Edge646
Pin Electronics Driver, Window
Comparator, and Switch Matrix
TEST AND MEASUREMENT PRODUCTS
Description
Applications
The Edge646 is an integrated trinary driver, window
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.
•
Low Cost Automated Test Equipment
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.
VH VTT VL
The Edge646 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.
