Description
Features
Edge819
Octal, 18V Pin
Electronics Driver
The Edge819 is an octal pin electronics driver 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 Edge819 incorporates eight channels of programmable
drivers into one 14 mm X 20 mm 100 pin MQFP package.
Each channel has per pin driver levels, data, and high
impedance control.
• 18V I/O Range
• 50 MHz Operation
• Per Pin Flexibility
• Flex In Digital Inputs
• Small footprint (100 pin MQFP)
The Edge819 uses "Flex In" digital inputs and, therefore,
can mate directly with any digital technology.
The Edge819 is pin and functionally compatible with the
Edge818, except the Edge819 does not have any
comparators.
The 18V driver output range allows the Edge819 to
interface directly with TTL, ECL, CMOS (3.3V and 5V),
LVCMOS, and custom level circuitry, as well as the high
voltage (Super Voltage) level required for many special
test modes for Flash Devices.
Applications
