Description
Edge693
500 MHz Monolithic
Dual Pin Electronics Driver
Applications
The Edge693 is a dual pin electronics driver solution • Memory Test Equipment
manufactured in a high-performance, complementary • Instrumentation
bipolar process. In Automatic Test Equipment (ATE)
applications, the Edge693 offers two pin drivers suitable
for drive-only channels in memory testers, as well as for
bidirectional channels in memory, VLSI, and mixed- signal
test systems.
Each driver is completely isolated from the other. There
are separate data, enable, slew rate adjust, high and
low levels; as well as power supply inputs for each driver.
The driver output slew rate is adjustable from 3 V/ns to
1 V/ns, allowing the matching of edges from channel-to-
channel, as well as slowing down edges for noise
sensitive applications.
Each driver is capable of driving 9 V signals over a 12 V
range, in addition to going into a high impedance state.
The Edge693 can generate ECL signals up to 500 MHz
and 3V signals in excess of 300 MHz.
Combining two independent drivers into a 28-pin PLCC
package offers a highly integrated solution appropriate
where speed and density are at a premium.
Features
• >2.5 V/ns Driver Slew Rates
• Adjustable Driver Slew Rates
• HiZ Capability
• 12 V Output Range
• 9 V Output Swings
• 28-Pin PLCC with an Internal
Heat Spreader

Thermal equilibrium is established by applying power for at least 2 minutes while maintaining a transverse
air flow of 400 linear feet per minute over the device mounted either in the test socket or on the printed
circuit board. Thermal resistance measurements are taken with device soldered to PCB.
