Quad Voltage Comparators for Industrial,
Commercial and Military Applications
The devices in this series consist of four independent single
or dual supply voltage comparators on a single monolithic
substrate. The common mode input voltage range includes
ground even when operated from a single supply, and the
low power supply current drain makes these comparators
suitable for battery operation. These types were designed to
directly interface with TTL and CMOS.
Type CA139A, has a lower input offset voltage than the
CA139. Some of the SOIC parts are available on tape and
reel (see Ordering Information table). Replace the M suffix in
the part number with M96 when ordering (e.g.,
CA0239M96).

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. Inputs must not go more negative than -0.3V.
2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current independent of V+ is
approximately 20mA.

5. The comparator will provide a proper output state even if the positive swing of the inputs exceeds the power supply voltage level, if the other
input remains within the common mode voltage range. The low input voltage state must not be less than -0.3V (or 0.3V below the magnitude of
the negative power supply, if used).
6. The upper end of the common mode voltage range is (V+) - 1.5V, but either or both inputs can go to +30V without damage.
