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 the fact that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

At output switch point, VO 1.4V, RS =0withVCC + from 5Vto 30V, and over the full input common-mode range (0V to VCC + 1.5V). 3. 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. 4. The input common-mode voltage of either input signal voltage should not be allowed to go negati ve 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 +30V without damage. 5. The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be obtained. 6. 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, i f used). 1 na na V/mV ma V V mv na µa ma µs 3/9

Destructive di ssipation can result from simultaneous short-circuit on all amplifiers. 2. The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output so no loading change exists on the input lines. 3. V o = 1.4V, R s =0Ω, 5V < V CC + < 30V, 0 < V ic <V CC V 4. 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 V, but either or both inputs can go to +32V without damage. 5. Due to the proximity of external components insure that coupling is not originating via stray capacitance between these external parts. This typically can be detected as this type of capacitance increases at higher frequences. 6. This input current only exists 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 becoming forward biased and thereby acting as input diodes clamps. In addition to this diode action, there is also NPN parasitic action on the IC chip. this transistor action can cause the output voltages of the Op-amps to go to the V CC voltage level (or to ground for a large overdrive) for the time duration than an input is driven negative. This is not destructive and normal output will set up again for input voltage higher than -0.3V. mv V/µs MHz % nv Hz TBL 4/11

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 or input lines. 4. 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 +30V without damage. 5. The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be obtained. 6. As long as the other voltage remains within the common-mode range the comparator will provide a proper output state.
