TS3702IPT

双微功耗CMOS电压比较器 MICROPOWER DUAL CMOS VOLTAGE COMPARATORS

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.

Thus response times remain similar to the LM393.
