Low Power Dual Voltage Comparators
Wide single supply voltage range or dual supplies : +2V to +36V or 1V to 18V Very low supply current (0.4mA) independent of supply voltage (1mW/ comparator at +5V) Low input bias current: 25nA typ. Low input offset current: 5nA typ. Low input offset voltage: 1mV 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

D SO-8 (Plastic Micropackage)
P TSSOP8 (Thin Shrink Small Outline Package)
Description
These devices consist of two independent low 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.

1) Short-circuits 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+. 2) Pd is calculated with Tamb = +25C, Tj = +150C and Rthja = 100C/W for DIP8 package = 175C/W for SO8 package = 200C/W for TSSOP8 package = 215C/W for Mini SO8 package

At output switch point, Vo 1.4V, Rs = 0 with VCC+ from 5V to 30V, and over the full 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. The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be obtained. Posistive 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, if used).
