Edge649
Octal Pin Electronics
Driver/Receiver
EDGE HIGH-PERFORMANCE PRODUCTS
Description
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.
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:
鈥?reduced driver preshoot
鈥?faster driver propagation delay
鈥?superior driver pulse width distortion
鈥?higher driver Fmax operation
鈥?slightly slower driver output slew rates
鈥?higher comparator Fmax operation
鈥?lower comparator propagation delay
鈥?superior comparator pulse width
distortion.
