DESCRIPTION

This device consists of two independent low
power voltage comparators designed specifically
to operate from a single 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.

PAD LOCATIONS
ABSOLUTE MAXIMUM RATINGS
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 Vcc+ Pd is calculated with Tamb = +25°C, TJunction = +150°C and Rthja = 175°C/W for SO8 package

OPERATING CONDITIONS
ELECTRICAL CHARACTERISTICS
CC+ = 5V, Vcc- = GND, Tamb = 25°C (unless otherwise specified) At output switch point, VO ≈ 1.4V, RS = 0Ω with VCC+ from 5V to 30V, and over the full input common-mode range (0V to VCC+ –1.5V). 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 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. 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 below the negative power supply, if used) The response time specified is for a 100mV input step with 5mV overdrive. Maximum values are guaranteed by design & evaluation.
