The AS339/339A consists of four independent precision voltage comparators with a typical offset voltage of 2.0mV and high gain. They are specially designed to work over a wide range of voltages from a single power supply. Shunt power supply is also possible, and the low current consumption is independent of the supply voltage.

The AS339/339A series conforms to industry standard 339. The AS339A has a tighter input bias voltage than the AS339.

AS339 is available in SO-14 and tsso-14 packages, AS339A is available in SO-14 package. characteristic

Note: 4. Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, under these or any other conditions, the functional operation of the equipment beyond the "Recommended Operating Conditions" is an indication and is not meant to be. Exposure to Absolute Maximum Ratings for extended periods of time may affect device reliability. 5. This input current exists only when the voltage on any input lead is negative. This is due to the forward biasing of the collector-base junction of the input PNP transistor, which acts as an input diode clamp. In addition to diode action, there are lateral NPN parasitic transistor actions on integrated circuit chips. The action of this transistor allows the output voltage of the comparator to reach the V+ voltage level for a period of time during which the input is driven negative (or to ground in large overload conditions). This is not destructive, the normal output state will be re-established when the input voltage, which is negative, again returns a value greater than -0.3 VDC (at +25°C).
