Description
Features
Edge211
Dual Pin
Electronics Driver
The Edge211 is a dual trinary driver 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.
Each 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.
• 100 MHz Operation
• 12V I/O Range
• Programmable Output Levels
• Flex In digital Inputs (Technology Independent)
• Three Level Driver
• Extremely Low Leakage Currents (~0 nA)
• Small Footprint (32 Pin, 7 mm X 7 mm,
TQFP Package)
The Edge211 is intended to offer an extremely low leakage,
low cost, low power, small footprint, driver solution for
100 MHz and below pin electronics applications.

Circuit Description (continued)
Driver Output Protection
The Edge211 is designed to operate in a functional testing
environment where a controlled impedance (typically 50
Ohms) is maintained between the pin electronics and the
DUT. In general, there will be an external resistor at the
driver output which series terminates the transmission line
to the DUT. In this environment, the driver can withstand
a short to any legal DUT voltage for an indefinite amount
of time.
In a low impedance application with no additional output
series resistance, care must be exercised and systems
should be designed to check for this condition and tristate
the driver if a short is detected.
The driver does NOT have on-chip short circuit protection
or limitation circuitry.
