A Product Line of
Diodes Incorporated
Description
The AS339/339A consist of four independent precision voltage
comparators with a typical offset voltage of 2.0mV and high gain.
They are specifically designed to operate from a single power supply
over wide range of voltages. Operation from split power supply is also
possible and the low power supply current drain is independent of the
magnitude of the power supply voltage.
The AS339/339A series are compatible with industry standard 339.
The AS339A has more stringent input offset voltage than the AS339.
The AS339 is available in DIP-14, SOIC-14 and TSSOP-14
packages, and the AS339A is available in SOIC-14 package.

Functional Block Diagram
Absolute Maximum Ratings (Note 1)
Notes: 1. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stres s ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Conditions” is not implied.
Exposure to “Absolute Maximum Ratings” for extended periods may affect device reliability.
2. 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 VDC (at +25oC).

Notes: 3. Limits over the full temperature are guaranteed by design, but not tested in production.
4. The input common-mode voltage of either input signal voltage should not be allowed to go negatively by more than 0.3V (at +25oC). The upper end of the
common-mode voltage range is VCC -1.5V (at +25oC), but either or both inputs can go to +36V without damages, independent of the magnitude of the V
CC.
