LM106/LM306
Voltage Comparator
General Description
The LM106 series are high-speed voltage comparators designed to accurately detect low-level analog signals and
drive a digital load. They are equivalent to an LM710, combined with a two input NAND gate and an output buffer. The
circuits can drive RTL,DTLor TTL integrated circuits directly.
Furthermore, their outputs can switch voltages up to 24V at
currents as high as 10 mA.
The devices have short-circuit protection which limits the inrush current when it is used to drive incandescent lamps, in
addition to preventing damage from accidental shorts to the
positive supply.The speed is equivalent to that of an LM710.
However, they are even faster where buffers and additional
logic circuitry can be eliminated by the increased flexibility of
the LM106 series. They can also be operated from any
negative supply voltage between −3V and −12V with little effect on performance.
The LM106 is specified for operation over the −55˚C to
+125˚C military temperature range. The LM306 is specified
for operation over 0˚C to +70˚C temperature range.
