LTC6752 and LTC6754 UltraFast Comparators

Linear Technology offers its rail-to-rail comparator interface to 1.8 V CMOS and LVDS

Image of Linear Technology's LTC6752 and LTC6754 UltraFast ComparatorsLinear Technology rail-to-rail comparators combine ultrafast performance, small packages, and many features. The LTC6754 LVDS comparators support toggle rates up to 890 Mbps and 1.8 ns propagation delay. The LTC6752 comparators interface to CMOS down to 1.8 V, exhibit a propagation delay of 2.9 ns, and support toggle rates up to 280 MHz. Available features include a separate output supply, shutdown, output latch, adjustable hysteresis, and complementary outputs. With high performance and a wide selection, the result is true design flexibility.
