Edge846
Pin Electronics Driver, Window
Comparator, and Switch Matrix
TEST AND MEASUREMENT PRODUCTS
Description
The Edge846 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.
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.
The switches are included to allow such functions as PMU,
pull-up, and pull-down connections.
The Edge846 is intended to offer an extremely low leakage,
low cost, low power, highly integrated, per pin solution
for 50 MHz and below pin electronics applications.
