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.

(Thin Shrink Small Outline Package)

Thus response times remain similar to the LM393.

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 = +25°C, Tj = +150°C and R thja = 100°C/W for DIP8 package
= 175°C/W for SO8 package
= 200°C/W for TSSOP8 package
