Revision 2 /October 27, 2000

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.

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 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.
