COMPATIBLE WITH BIPOLAR LM393 DESCRIPTION The TS3702 is a micropower CMOS dual voltage comparator with extremely low consumption of 9A 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. Thus response times remain similar to the LM393. ORDER CODE

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.
Pd is calculated with T amb = +25C, Tj = +150C and R thja = 100C/W for DIP8 package = 175C/W for SO8 package = 200C/W for TSSOP8 package
