±18V.VERY LOW SUPPLY CURRENT(0.4mA) INDE-
PENDENT OF SUPPLY VOLTAGE mW/comparatorat +5V).LOW INPUT BIAS CURRENT: 25nA TYP.LOW INPUT OFFSET CURRENT: ±5nA TYP.INPUT COMMON-MODE VOLTAGE RANGE
INCLUDES GROUND.LOW OUTPUT SATURATION VOLTAGE:
250mV TYP.(IO= 4mA).DIFFERENTIAL INPUT VOLTAGE RANGE
EQUAL TO THE SUPPLY VOLTAGE.TTL, DTL, ECL, MOS, CMOS COMPATIBLE
OUTPUTS
DESCRIPTIONThis device consistsof two independent low power
voltage comparators designed specificallyto oper-
ate froma single supply overa wide rangeof volt-
ages. Operation from split power suppliesis also
possible.
These comparators also have a unique
characteris-tic in the fact that the input com-
mon-mode voltage range includes ground even
though operated froma single power supply volt-
age.
