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 (±1.35V 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.
