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 Maximum 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 di ode action, there is also lateral NPN parasi tic 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 V DC (at 25oC). BCD Semiconductor's Pb-free products, as designated with "E1" suffix in the part number, are RoHS compliant.

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 25oC). The upper end of the common-mode voltage range is VCC-1.5V (at 25oC), but either or both inputs can go to +18V without damages, independent of the magnitude of the VCC. Limits in standard typeface are for T A=25oC, bold typeface applies over T A=-40oC to 85 oC (Note 3), V CC=5V , GND=0V , unless otherwise specified.
