Description
Edge818
Octal 18V Pin Electronics
Driver/window Comparator
Features
The Edge818 is an octal pin electronics driver and window
comparator fabricated in a wide voltage CMOS process.
It is designed specifically for Test During Burn In (TDBI)
applications, where cost, functional density, and power
are all at a premium.
The Edge818 incorporates eight channels of
programmable drivers and window comparators into one
14 mm X 20 mm 100 pin MQFP package. Each channel
has per pin driver levels, data, and high impedance
control. In addition, each comparator has per pin high
and low threshold levels.
The Edge818 uses "Flex In" and "Flex Out" digital inputs,
and can therefore mate directly with any digital technology
providing a minimum 2V swing. The digital outputs can
mate directly with any digital technology.
The 18V driver output and receiver input range allow the
Edge818 to interface directly with TTL, ECL, CMOS (3V,
5V, and 7V), LVCMOS, and custom level circuitry, as well
as the high voltage (Super Voltage) level required for
many special test modes for Flash Devices.
