Description
Features
Edge749
Octal Pin Electronics
Driver/Receiver
The Edge749 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 Edge749 incorporates eight channels of
programmable drivers and receivers into one package.
Each channel has per pin driver levels, receiver threshold,
and tristate control.
• 20 MHz Operation
• 18 V DUT I/O Range
• Programmable Output Levels
• Programmable Input Thresholds
• Per Pin Flexibility
• High Integration Levels
• Low Power Dissipation
• Edge 648 and 649 Compatible
The 18V driver output and receiver input range allows
the Edge749 to interface directly between TTL, ECL,
CMOS (3V, 5V, and 8V), very high voltage, and custom
level circuitry.
The Edge749 is pin and functionally compatible with the
Edge648 and Edge649.
