APPLICATIONS INFORMATION

turn off. The collector of Q2 can be now held at any voltage
above V

emitter can be held at any voltage between V
long as it is negative with respect to the collector.
In the “on” state, I
Diodes D1 and D2 prevent deep saturation of Q2 to improve
speed and also limit the drive current of Q1. The R1/R2
divider sets the saturation voltage of Q2 and provides turn-
off drive. Either the collector or emitter pin can be held at
a voltage between V

When the emitter is used as the output, the collector is
typically tied to V
or V

Input Signal Range
The common mode input voltage range of the LT1011 is
about 300mV above the negative supply and 1.5V below the
positive supply, independent of the actual supply voltages
(see curve in the Typical Performance Characteristics). This
is the voltage range over which the output will respond
correctly when the common mode voltage is applied to
one input and a higher or lower signal is applied to the
remaining input. If one input is inside the common mode
range and one is outside, the output will be correct. If the
inputs are outside the common mode range in opposite
directions, the output will still be correct. If both inputs are
outside the common mode range in the same direction,
the output will not respond to the differential input; for
temperatures of 25°C and above, the output will remain
unconditionally high (collector output), for temperatures
below 25°C, the output becomes undefi ned.
