OUTPUTS DESCRIPTION This device consists of four independent precision voltage comparators. All these comparators were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage. ORDER CODE

1. Short-circuit from the output to Vcc+ can cause excessive heating and eventual destruction. The maximum output current is approximately 20mA, independent of the magnitude of V cc+ 2. Maximum power dissipation has been calculated with R thj-a= 150C/W for SO14 package, TA=+25C and TJ=+150C

1. At output switch point, VO 1.4V, RS = 0 with VCC+ from 5V to 30V, and over the full input common-mode range (0V to VCC + -1.5V). 2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference of input lines 3. 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 VCC+ -1.5V, but either or both inputs can go to +30V without damage. 4. The response time specified is for a 100mV input step with 5mV overdrive. 5. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than -0.3V (or 0.3V bellow the negative power supply, if used) 6. Maximum values are guaranteed by design.
