TEST AND MEASUREMENT PRODUCTS
Description
Features
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.

Per Pin Flexibility
Flex In Digital Inputs
Small footprint (100 pin MQFP)
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.
The Edge819 uses "Flex In" digital inputs and, therefore,
can mate directly with any digital technology.
Applications
The Edge819 is pin and functionally compatible with the
Edge818, except the Edge819 does not have any
comparators.
• Burn In ATE
• Low Cost ATE
• Instrumentation
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.

Circuit Description
Driver Description
Driver High and Low
The Edge819 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.
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.

In a functional testing environment, where a resistor is
added in series with the driver output to create a 50Ω
driver, the Edge819 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.

With EN* high, the driver goes into a high impedance state.
With EN* low, DATA high forces the driver into a high state,

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.
The three diode configuration shown in Figure 1 should
be used on a once-per-board basis.
VH and VL Decoupling
VCC
External
Logic
Supply
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.
VDD
1N5820 or
Equivalent
For applications where VH and VL are shared over multiple
channels, a solid power plane to distribute these levels is
preferred.
External
System
Ground
VEE
VBB
The two VBB pins are connected together on-chip.
Therefore, only one VBB needs to be connected to for
proper 819 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 819.
Power Supplies
The Edge819 has several power supply requirements to
protect the part in power supply fault situations, as well
as during power up and power down sequences.
The following power supply requirements must be satisifed
at all times:
Figure 1.
Power Supply Protection Scheme
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.
VEE ≤ All I/O Pins ≤ VCC at all times
The power sequence below can be used as a guideline
when operating the Edge819:
