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.

Small footprint (100 pin MQFP)
Applications
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.
• Burn In ATE
• Low Cost ATE
• Instrumentation
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.

Circuit Description
Driver Description
VH
The Edge818 supports programmable high and low levels
and tristate per channel. There are no shared lines
between any drivers. The EN* and DATA signals are
wide voltage high impedance analog inputs capable of
receiving digital signals over a wide common mode range.
VBB is the high impedance analog input which sets the
threshold for EN* and DATA.

Driver Output Protection
In a functional testing environment, where a resistor is
added in series with the driver output to create a 50Ω
driver, the Edge818 can withstand a short to any legal
voltage for an indefinite amount of time.
In a low impedance application, with no additional output
resistance, the system should be designed to check for
a short circuit prior to connecting the driver, and tristate
the driver if a short is detected.
Drive High and Low
VH and VL define the logical "1" and "0" levels of the
driver, and can be adjusted anywhere over the range
determined by VCC and VEE. There are no restrictions
between VH and VL, other than they must remain within
the power supply levels.
VEE ≤ VH ≤ VCC
VEE ≤ VL ≤ VCC
The VH and VL inputs are unbuffered in that they also
provide the driver output current (see Figure 3), so the
source of VH and VL must have ample current drive
capability.

Receiver Description
The Edge818 supports a window comparator with
independent threshold levels per channel. There are no
shared comparator lines between channels. CVA and
CVB are high impedance analog voltage inputs which
define the threshold voltages for comparators A and B.
If VINP is more positive than CVA or CVB, QA and QB will
be high. Otherwise, QA and QB will be low.

Circuit Description (continued)
The comparator outputs are "Flex Out". They are
technology independent and may be adjusted over a wide
voltage common mode range. COMP HIGH and COMP
LOW are analog inputs which set the digital high and low
levels (respectively) of QA and QB. COMP HIGH and
COMP LOW are unbuffered inputs that provide the
necessary drive current, so the sources for these levels
must have adequate current capability.

Unbuffered Comparator Output Stage
Typically, COMP HIGH and COMP LOW will be connected
to the digital power supplies of the chip receiving QA
and QB.
Receiver Headroom
There is ~2V of headroom required between the
comparator thresholds and both power supply levels.

Application Information
Power Supply Decoupling
VCC and VEE should be decoupled to GND with a .1 µF
chip capacitor in parallel with a .001 µF chip capacitor.
A VCC and VEE plane, or at least a solid power bus, is
recommended for optimal performance.
must always be positive (above ground), and VEE must
always be negative (at or below ground).
The three diode configuration shown in Figure 5 should
be used on a once-per-board basis.
VH and VL Decoupling
As the VH and VL inputs are unbuffered and supply the
driver output current, which can be quite large during
edge transitions, decoupling capacitors for these inputs
are recommended in proportion to the amount of output
current requirements.
VCC
VDD
For applications where VH and VL are shared over multiple
channels, a solid power plane to distribute these levels
is preferred.
1N5820 or
Equivalent
VBB
The two VBB pins are connected together on-chip.
Therefore, only one VBB needs to be connected to for
proper 818 operation.
The two pins may be used to daisy chain a VBB signal
across a PC Board without having to route the actual
signal underneath the 818.
Latchup Protection
The Edge818 has several power supply requirements to
protect the part in power supply fault situations, as well
as during power up and power down sequences. VCC
must remain greater than or equal to VDD (external supply
for the digital logic) at all times. Both VCC and VDD

Warning: It is extremely important that the voltage on
any device pin does not exceed the range of VEE –
0.5V to VCC +0.5V at any time, either during power up,
normal operation, or during power down. Failure to
adhere to this requirement could result in latchup of
the device, which could be destructive if the system
power supplies are capable of supplying large amounts
of current. Even if the device is not immediately
destroyed, the cumulative damage caused by the stress
of repeated latchup may affect device reliability.
