LM106/LM306
Voltage Comparator
General Description The LM106 is specified for operation over the −55˚C to
+125˚C military temperature range. The LM306 is specified
The LM106 series are high-speed voltage comparators de- for operation over 0˚C to +70˚C temperature range.
signed to accurately detect low-level analog signals and
drive a digital load. They are equivalent to an LM710, com-
bined with a two input NAND gate and an output buffer. The Features
circuits can drive RTL, DTL or TTL integrated circuits directly. n Improved accuracy
Furthermore, their outputs can switch voltages up to 24V at n Fan-out of 10 with DTL or TTL
currents as high as 10 mA. n Added logic or strobe capability
The devices have short-circuit protection which limits the in- n Useful as a relay or lamp driver

addition to preventing damage from accidental shorts to the n 40 ns maximum response time
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 ef-
fect on performance.

 Electrical Characteristics (Note 2) (Continued)

Note 1: The maximum junction temperature of LM106 is 150˚C, LM306 is 85˚C. For operating at elevated temperatures, devices must be derated based on a thermal
resistance of 170˚C/W, junction to ambient, or 23˚C/W, junction to case.
Note 2: These specifications apply for −3V ≥ V− ≥ −12V, V+ = 12V and TA = 25˚C unless otherwise specified. All currents into device pins are considered positive.
Note 3: The offset voltages and offset currents given are the maximum values required to drive the output down to 0.5V or up to 4.4V (0.5V or up to 4.8V for the
LM306). Thus, these parameters actually define an error band and take into account the worst-case effects of voltage gain, specified supply voltage variations, and
common mode voltage variations.
Note 4: The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.
Note 5: All currents into device pins are considered positive.
Note 6: Refer to RETS106X for LM106 military specifications.
