OW POWER QUAD VOLTAGE COMPARATORS

GENERAL DESCRIPTION

This device consists of four independent precision voltage
comparators with an offset voltage specification as low as 2mV
max for CM339. 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.

Notes : 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 input common-mode voltage of the either input signal voltage should not be allowed to go negative by more than

+

0.3V. The upper and of the common-mode voltage range is Vcc

-1.5V, but either or both inputs can go to +30V

without damage.

3.The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be
obtained.

4.Positive excursions of input voltage may 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）.
