TS3702 Micropower dual CMOS voltage comparators Features ■ Push-pull CMOS output (no external pull-up resistor required) ■ Extremely low supply current: 9μA typ / comparator ■ Wide single supply range: 2.7V to 16V or dual supplies (±1.35V to ±8V) ■ Extremely low input bias current: 1pA typ ■ Extremely low input offset currents: 1pA typ ■ Input common-mode voltage range includes GND ■ High input impedance: 1012Ω typ ■ Fast response time: 2μs typ for 5mV overdrive ■ Pin-to-pin and functionally compatible with bipolar LM393 N DIP8 (Plastic package) D SO8 (Plastic micropackage) P TSSOP8 (Thin shrink small outline package) 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 opencollector output comparators.

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 and negative supply voltages. 4. Guaranteed by design. 5. Pd is calculated with Tamb = +25°C, Tj = +150°C and Rthja = 100°C/W for DIP8 package Rthja = 175°C/W for SO8 package Rthja = 200°C/W for TSSOP8 package 6. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a 1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 7. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5Ω). This is done for all couples of connected pin combinations while the other pins are floating. 8. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. Table 2.
