Key Featrues

UltraFast Response Time (7ns): The LT1394 comparator offers an exceptionally fast response time of 7 nanoseconds, making it ideal for high-speed applications such as A/D converters, line receivers, and pulse height/width discriminators. This feature ensures rapid signal processing, enhancing system performance in time-critical environments.
Low Power Consumption (6mA): With a quiescent current of just 6mA, the LT1394 is designed for energy-efficient operation. This low power consumption makes it suitable for battery-powered devices and applications where minimizing power usage is critical, without compromising on speed or accuracy.
Wide Input Common Mode Range: The comparator's input common mode range extends from 1.5V below the positive supply to the negative supply rail. This flexibility allows it to handle a wide range of input signals, making it versatile for use in ground-sensing and precision applications.
Complementary TTL Outputs: The LT1394 features complementary TTL outputs, enabling direct interfacing with TTL or CMOS logic. This simplifies circuit design and reduces the need for additional components, improving system efficiency and reducing overall design complexity.
Output Latch Capability: The inclusion of an output latch allows the LT1394 to hold its output state, which is particularly useful in applications requiring stable output signals, such as sampling circuits or triggers. This feature enhances reliability and ensures consistent performance in dynamic environments.
