The LM306 is a high-speed voltage comparator with differential inputs, a low-impedance high-
sink-current (100 mA) output, and two strobe inputs. This device detects low-level analog or digital signals and can drive digital logic or lamps and relays directly. Short-circuit protection and surge-current limiting is provided.

A low-level input at either strobe causes the output to remain high regardless of the differential input.When both strobe inputs are either open or at a high logic level, the output voltage is controlled by the differential input voltage. The circuit will operate with any negative supply voltage between -3 V and -12 V with little difference in performance.

The LM306 is characterized for operation from 0°C to 70°C.
