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.
