1 TS39/A/B/C UNISONIC TECHNOLOGIES CO., LTD LOW POWER SINGLE VOLTAGE COMPARATOR DESCRIPTION The UTC TS39/A/B/C consists of a low power voltage comparator designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. This comparator also has a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage. FEATURES * Wide single supply voltage range or dual supplies +2V~+36V or ±V~±8V * Very low supply current (.2mA) independent of supply voltage (mw /comparator at +V) * Low input bias current: 2nA typ. * Low input offset current: ±na typ. * Low input offset voltage: ±mv typ * Input common-mode voltage range includes ground. * Low output saturation voltage: 2mV typ.(i OUT =ma). * Differential input voltage range equal to the supply voltage. * TTL, DTL, ECL, CMOS Compatible outputs.

Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. Short-circuit from the output to V CC can cause excessive heating and eventual destruction. The maximum output current is approximately 2mA, independent of the magnitude of V CC.

At output switch point, Vo=.V, R S =Ω with V CC from V ~ 3V and over the full input common-mode range (V ~ V CC.V). 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 or input lines. 3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than.3v.the upper end of the common-mode voltage range is V CC + -.V,but either or both inputs can go to +3V 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 -.3V (or.3v below the negative power supply, if used).. The response time specified is for a mv input step with mv overdrive. For larger overdrive signals 3ns can be obtained. UNISONIC TECHNOLOGIES CO., LTD of 6
