Ordering Information

LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS AZ393/393C Aug. 2006 Rev. 1. 2 BCD Semiconductor Manufacturing Limited Data Sheet Note 1: Stresses greater than those listed under "A bsolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings on ly, 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 transistor s becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is al so lateral NPN parasitic tran sistor 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 out- put states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.3 V DC (at 25oC).

Note 4: The direction of the input current is out of the PN P input stage. This current is essentially constant, inde- pendent of the state of the output, so no loading charge exists on the reference of input lines. Note 5: The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V . The upper end of the common-mode voltage range is V CC-1.5V , but either or both inputs can go to +18V without damage, independent of the magnitude of VCC. Note 6: The response time specified is a 100mV input step with 5mV overdrive. For large overdrive signals 300ns can be obtained.
