The LM319 is a dual high-speed comparator IC manufactured by STMicroelectronics. It features two independent comparators on a single monolithic chip, designed for precision applications requiring fast response times. The device typically achieves an 80-ns response time at ±15 V supply.
Key electrical characteristics include a maximum input current of 1 µA over temperature and a typical output current drive capability of 25 mA. It supports a wide range of supply voltages, from a single 5-V logic supply up to ±15 V dual supplies. The LM319 is specified for operation from 0°C to +70°C.
This comparator is available in a 14-SOIC surface-mount package. Its outputs are compatible with RTL, DTL, and TTL logic families, making it versatile for various digital and mixed-signal designs. The uncommitted collector output stage allows it to drive lamps and relays directly.
The LM319 is suitable for applications requiring high-speed signal comparison, such as in data acquisition systems, voltage monitoring, and control circuits.
