The LT1394—an overview

A new ultra-high speed, single supply comparator, the LT1394, features TTL-compatible complementary outputs and 7ns response time. Other capabilities include a latch pin and good DC input characteristics (see Figure 482.1). The LT1394’s outputs directly drive all 5V families, including the higher speed ASTTL, FAST and HC parts. Additionally, TTL outputs make the device easier to use in linear circuit applications where ECL output levels ...
