Electrical Characteristics
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits.
Note 2: For elevated temperature operation, T
either device is soldered in a printed circuit board in a still air environment. The low bias dissipation and the “ON-OFF” characteristic of the outputs keeps the chip
dissipation very small (P
Note 3: Short circuits from the output to V
Note 4: 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 tran-
sistors becoming forward biased and thereby acting as input clamp diodes. 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 voltage of the comparators to go to the V+ voltage level (or to ground for a large input overdrive) for the time du-
ration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which is negative, again returns to a
value greater than −0.3 V
Note 5: These specifications apply for V
tested. These parameters are not used to calculate outgoing AQL.
Note 6: 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 change exists on the reference or the input lines as long as the common-mode range is not exceeded.
Note 7: The input common-mode voltage or either input voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode volt-
age range is V
Note 8: The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 1.3 µs can be obtained. See Typical Performance
Characteristics section.
