LOW-POWER, LOW-OFFSET VOLTAGE QUAD COMPARATORS
FAIRCHILD LINEAR INTEGRATED CIRCUITS
GENERAL DESCRIPTION - The I"A139 series consists of four independent precision
voltage comparators designed specifically to operate from a single power supply.
Operation from split power supplies is also possible and the low power supply current
drain is independent of the supply voltage range. Darlington connected PNP input
stage allows the input common-mode voltage to include ground.

NOTES:
e1. For operating at high temperatures, the ~A339/~A339A, "A2901 ~A3302 must be derated based on a 125° maximum junction temperature and a thermal
resistance of 125°C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The ~A13g and ~A139A~
must be derated based on a 1500 C maximum junction temperature. The low bias dissipation and the "ON-OFF" characteristic of the outputs keeps the-
chip dissipation very small (Po:5 100 mWl, provided the output transistors are allowed to saturate.
2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately 20 rnA inde-
pendent 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 tiode 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 levellorto ground for a large over-
drive) for the time duration that an input is driven negative. This is not destructive and normal output states will reestablish when the input voltage, which
negative, again returns to a value greater than -0.3 V.
4. These specifications apply for V+ = 5.0 V and -55°C:::; TA:::; +125°C, unless otherwise stated. With the .uA239/.uA239A,all temperature specifications
are limited to -25° e:s TA:S +85° e, the ~A339/~A339A temperature specifications are limited to 0° e:s TA:S +700 e, and the :,A290t, ~A3302temperature
range is _40° C :::; T A :::; +85° C.
5. The direction of the input current is out of the Ie due to the Pr<JP input stage. This current is essentially constant, independent olthe state olthe output so
no loading change exists on the reference or input lines.
6. 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 voltalge range is V, -t.5 V, but either or both inputs can go to +30 V without damage.
7. The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained; see typical performance
characteristics section.
8. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, com-
parator will provide a proper output state. The low input voltage state must not be less than -0.3 V or 0.3 V below the magnitude of the negative power
supply, if used.
all9. At output switch point, Va" 1.4 V, As = with V' from 5 V; and over the full input common-mode range 10 V to V' -1.5 VI.
to. For input signals that exceed Vee, only the overdriven comparator is affected. With a 5 V supply, VIN should be limited to 25V max,and a limiting resistor
should be used on all inputs that might exceed the positive supply.
