Low power dual voltage comparator
LM193A/293/A/393/A/2903
DESCRIPTION
The LM193 series consists of two independent precision voltage
comparators with an offset voltage specification as low as 2.0 mV
max. for two comparators which were designed specifically to
operate from a single power supply over a wide range of voltages.
Operation from split power supplies is also possible, and the low
power supply current drain is independent of the magnitude of the
power supply voltage. These comparators also have a unique
characteristic in that the input common-mode voltage range includes
ground, even though operated from a single power supply voltage.
The LM193 series was designed to directly interface with TTL and
CMOS. When operated from both plus and minus power supplies,
the LM193 series will directly interface with MOS logic where their
low power drain is a distinct advantage over standard comparators.

C
2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately
20 mA independent of the magnitude of V+.
3. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the
input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral
NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the comparators to go to the V+ voltage
level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states
will re-establish when the input voltage, which was negative, again returns to a value greater than –0.3 V DC .

NOTES:
1. Positive excursions of input voltage may exceed the power supply level by 17 V. As long as the other voltage remains within the
common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than –0.3 V DC (V DC
below the magnitude of the negative power supply, if used).
2. At output switch point, V O 9
1.4 V DC , R S = 0
W
with V+ from 5 V DC to 30 V DC and over the full input common-mode range (0 V DC to
V+ –1.5 V DC ).
3. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of
the common-mode voltage range is V+ –1.5 V, but either or both inputs can go to 30 V DC without damage.
4. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of
the output so no loading change exists on the reference or input lines.
5. The response time specified is for a 100 mV input step with a 5 mV overdrive.
6. For input signals that exceed V CC , only the over-driven comparator is affected. With a 5 V supply, V IN should be limited to 25 V maximum,
and a limiting resistor should be used on all inputs that might exceed the positive supply.
