Description
The TS3702 is a micropower CMOS dual voltage
Pin connections
comparator with extremely low consumption of (Top view) 9μA typ / comparator (20 times less than bipolar LM393). The push-pull CMOS output stage allows power and space saving by eliminating the Output 1 1 8 + VCC external pull-up resistor required by usual open- Inverting Input 1 2 - 7 Output 2 + collector output comparators. Non-inverting Input 1 3 - 6 Inverting Input 2 V - 4 + 5 Non-inverting Input 2 CC Thus response times remain similar to the LM393.
