Overview
The LM306 is a high-speed voltage comparator produced by Texas Instruments. It features differential inputs, a low-impedance high-sink-current (100 mA) output, and two strobe inputs. This device is designed to detect low-level analog or digital signals and can drive digital logic, lamps, and relays directly. The LM306 offers short-circuit protection and surge-current limiting, ensuring robust operation under various conditions.
The LM306 is characterized for operation from 0°C to 70°C and can operate with any negative supply voltage between −3 V and −12 V with minimal performance variation. It is also designed to be interchangeable with the National Semiconductor LM306.
