TS3V3702 3V MICROPOWER DUAL CMOS VOLTAGE COMPARATORS ■ DEDICATED TO 3.3V OR BATTERY SUPPLY (specified at 3V and 5V) ■ PUSH-PULL CMOS OUTPUT (NO EXTER NAL PULL-UP RESISTOR REQUIRED) ■ EXTREMELY LOW SUPPLY CURRENT : 7µA typ / comparator N DIP8 (Plastic Package) ■ WIDE SINGLE SUPPLY RANGE 2.7V TO 16V ■ EXTREMELY LOW INPUT CURRENTS : 1pA typ ■ INPUT COMMON-MODE VOLTAGE RANGE INCLUDES GND ■ FAST RESPONSE TIME : 2µs typ for D SO8 (Plastic Micropackage) 5mV overdrive ■ PIN-TO-PIN AND FUNCTIONALLY COMPATIBLE WITH BIPOLAR LM393 DESCRIPTION The TS3V3702 is a micropower dual CMOS voltage comparator with extremely low consumption of 7µA 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.

Parameter Differential Input Voltage 2) Power Dissipation 5) DIP8 SO8 TSSOP8 Storage Temperature Range All voltage values, except differential voltage, are with respect to network ground terminal. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. The magnitude of the input and the output voltages must never exceed the magnitude of the possitive supply voltage. Guaranteed by design. 5.
