1 LOW POWER QUA CMOS VOLTAGE COMPARATOR WIE SINGLE SUPPLY RANGE OR UAL SUPPLIES 3V TO 6V OR ±.5V TO ±8V VERY LOW SUPPLY CURRENT:.mA/COMP INEPENENT OF SUPPLY VOLTAGE EXTREMELY LOW INPUT BIAS CURRENT : pa typ EXTREMELY LOW INPUT OFFSET CURRENTS : pa typ LOW INPUT OFFSET VOLTAGE INPUT COMMONMOE VOLTAGE RANGE INCLUES GN LOW OUTPUT SATURATION VOLTAGE 5mV TYP OUTPUT COMPATIBLE WITH TTL, MOS AN CMOS HIGH INPUT IMPEANCE : 2 Ω typ FAST RESPONSE TIME : 2ns TYP FOR TTL LEVEL INPUT STEP N IP4 (Plastic Package) SO4 (Plastic Micropackage) ESCRIPTION These devices consist of four independent precision voltage comparators, designed to operate with single or dual supplies. PIN CONNECTIONS (top view) These differential comparators use the STMicroelectronics silicon lin MOS process giving them an excellent consumptionspeed ratio. These devices are ideally suited for low consumption applications.

All voltage values, except differential voltage, are with respect to network ground terminal. 2. ifferential voltages are the noninverting input terminal with respect to the inverting input terminal. 3. The magnitude of the input and the output voltages must never exceed the magnitude of the possitive supply voltage. 4. Guaranteed by design. 5. Short circuit from outputs to Vcc can cause excessive heating and eventual destruction. 6.
