description

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.
