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. STROBE 1 STROBE 2 IN+ OUT IN − 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.

Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, except differential voltages and the voltage from the output to VCC −, are with respect to the network ground. 2. Differential voltages are at IN+ with respect to IN −. 3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 7 V, whichever is less. 4. The output may be shorted to ground or either power supply.
