Revision 1/ October 28, 1996

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 incor porates eight channels of

programmable drivers and receivers into one package.

Each channel has per pin driver levels, receiver threshold,

and tristate control.

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.

• 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

• Burn-In ATE

• Functional Board Testers

• In-Circuit Board Testers

• Combinational Board Testers

• Low Cost Chip Testers

• ASIC Verifiers

• VXI-Based Test Equipment
