DESCRIPTION
The TS3704 is a micropower CMOS quad voltage comparator with extremely low consumption
of 9μA typ / comparator (20 times less than bipolar LM339). 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 LM339.

Notes : 1. |
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 positive supply voltage. |
4. |
Short circuit from outputs to VCC+ can cause excessive heating and eventual destruction. |
