General Description
The COMLINEAR CLC2500 is a sub-nanosecond dual comparator with propa-
gation delay variation less than 100ps from 5 to 50mV input overdrive volt-
age. The input slew rate is 10V/ns and the differential input stage has a
common-mode input range of -2.5V to 4V.
The COMLINEAR CLC2500 has ECL-compatible complementary digital outputs
that are capable of driving 50Ω terminated transmission lines. The CLC2500
is ideally suited for automated test equipment (ATE) applications, high-speed
instrumentation, and peak detection.
