The LT1394 is an UltraFast (7ns) comparator with complementary outputs and latch. The input common mode range extends from 1.5V below the positive supply down to the negative supply rail. Like the LT1016, LT1116 and LT1671, this comparator has complementary outputs designed to interface directly to TTL or CMOS logic. The LT1394 may operate from either a single 5V supply or dual ±5V supplies. Low offset voltage specifications and high gain allow the LT1394 to be used in precision applications.
The LT1394 is designed for improved speed and stability for a wide range of operating conditions. The output stage provides active drive in both directions for maximum speed into TTL, CMOS or passive loads with minimal cross-conduction current. Unlike other fast comparators, the LT1394 remains stable even for slow transitions through the active region, which eliminates the need to specify a minimum input slew rate.
The LT1394 has an internal, TTL/CMOS compatible latch for retaining data at the outputs. The latch holds data as long as the LATCH pin is held high. Device parameters such as gain, offset and negative power supply current are not significantly affected by variations in negative supply voltage.
