It is 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 GS331 is available in standard SOT-23-5 package.

These are stress 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 Max-imum Ratings" for extended periods may affect device reliability. Note 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 25°C).

Bold typeface applies over TA=-40 to 85oC (Note 3) Note 3: These specifications are limited to -40oC≤TA≤85oC. Limits over temperature are guaranteed by design, but not tested in production. Note 4: The input common mode voltage of either input signal voltage should not be allowed to go negatively by more than 0.3V (at 25°C). The upper end of the common mode voltage range is VCC-1.5V (at 25°C), but either or both inputs can go to 18V without damages, March 2020-REV_V0 independent of the magnitude of the VCC. 3/10 GS331 Typical Performance characteristics March 2020-REV_V0 4/10 GS331 Typical Performance Characteristics (Continued) March 2020-REV_V0 5/10 GS331 Typical Performance Characteristics (Continued) March 2020-REV_V0 6/10 GS331 Typical Performance Characteristics (Continued) March 2020-REV_V0 7/10 GS331 Typical Performance Characteristics (Continued) March 2020-REV_V0 8/10 GS331 Typical Applications March 2020-REV_V0 9/10 GS331 Package Information SOT23-5 March 2020-REV_V0 10/10
