1 , A, LM293, LM293A, LM393, LM393A Low Power Dual oltage Comparators Wide single-supply voltage range or dual supplies: +2 to +36 or ± to ±8 ery low supply current (.4mA) independent of supply voltage (mw/comparator at +) Low input bias current: 25nA typ. Low input offset current: ±5nA typ. Low input offset voltage: ±m typ. Input common-mode voltage range includes ground Low output saturation voltage: 25m typ. (Io = 4mA) Differential input voltage range equal to the supply voltage TTL, DTL, ECL, MOS, CMOS compatible outputs 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 N DIP8 (Plastic Package) D SO-8 (Plastic Micropackage) P TSSOP8 (Thin Shrink Small Outline Package) S Mini SO-8 (Plastic Micropackage) Pin connections (top view) Output 2 - Inverting input 3 - Non-inverting input 4 - CC Non-inverting input Inverting input Output CC + February 26 Rev. 6 /5 5

At output switch point, o.4, R s = with CC + from to 3, and over the full common-mode range ( to CC + -.). 2. 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. 3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than.3. The upper end of the common-mode voltage range is CC + -., but either or both inputs can go to +3 without damage. 4. The response time specified is for a m input step with 5m overdrive. For larger overdrive signals 3ns can be obtained. 5. 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 -.3 (or.3 bellow the negative power supply, if used). 5/5
