TS3702C,I,M MICROPOWER DUAL CMOS VOLTAGE COMPARATORS ■ PUSH-PULL CMOS OUTPUT (NO EXTER NAL PULL-UP RESISTOR REQUIRED) ■ EXTREMELY LOW SUPPLY CURRENT : 9µA typ / comparator ■ WIDE SINGLE SUPPLY RANGE 2.7V TO 16V OR DUAL SUPPLIES (±1.5V TO ±8V) ■ EXTREMELY LOW INPUT BIAS CURRENT : N DIP8 (Plastic Package) 1pA typ ■ EXTREMELY LOW INPUT OFFSET CURRENTS : 1pA typ ■ INPUT COMMON-MODE VOLTAGE RANGE INCLUDES GND ■ HIGH INPUT IMPEDANCE : 1012Ω typ ■ FAST RESPONSE TIME : 2µs typ for D SO8 (Plastic Micropackage) 5mV overdrive ■ PIN-TO-PIN AND FUNCTIONALLY COMPATIBLE WITH BIPOLAR LM393 DESCRIPTION The TS3702 is a micropower CMOS dual voltage comparator with extremely low consumption of 9µA typ / comparator (20 times less than bipolar LM393). The push-pull CMOS output stage allows power and space saving by eliminating the external pull-up resistor required by usual open-collector output comparators. P TSSOP8 (Thin Shrink Small Outline Package) PIN CONNECTIONS (top view) Thus response times remain similar to the LM393.

All voltage values, except differential voltage, are with respect to network ground terminal. 2. Differential voltages are the non-inverting 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.
