Features
Edge649
Octal Pin Electronics
Driver/Receiver
The Edge649 is an octal pin electronics driver and
receiver combination fabricated in a high- performance
CMOS process. It is designed for automatic test
equipment and instrumentation where cost, functional
density, and power are all at a premium.
The Edge649 incorporates eight channels of
programmable drivers and receivers into one package.
Each channel has per pin driver levels, receiver threshold,
and tristate control.
• 50 MHz Operation
• 11 V DUT I/O Range
• Programmable Output Levels
• Programmable Input Thresholds
• Per Pin Flexibility
• High Integration Levels
• 615 mW Quiescent Power Dissipation
• Edge648 Compatible
The 11V driver output and receiver input range allows
the Edge649 to interface directly between TTL, ECL,
CMOS (3V, 5V, and 8V), and custom level circuitry.
The Edge649 is pin and functionally compatible with the
EDGE648, with the following performance differences:
• reduced driver preshoot
• faster driver propagation delay
• superior driver pulse width distortion
• higher driver Fmax operation
• slightly slower driver output slew rates
• higher comparator Fmax operation
• lower comparator propagation delay
• superior comparator pulse width
distortion.

Circuit Description (continued)
Driver Output Protection
In a functional testing environment, where a resistor is
added in series with the driver output, the Edge649 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.
Receiver Functionality
Edge649 supports programmable thresholds per
channel. There are no shared lines between comparators.
THRESHOLD is a high input impedance analog input
which defines a logical “1” and “0” at the DUT (see
Figure 4). If the DUT voltage is more positive than
THRESHOLD, DATA OUT will be high. With DUT lower
than THRESHOLD, DATA OUT will be low.
