TS393 Micropower Dual CMOS Voltage Comparators ■ Extremely low supply current: 9µa typ/comp. ■ 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 current: 1pA typ. ■ Input common-mode voltage range includes GND ■ High input impedance: 1012Ω typ ■ Fast response time: 2.5µs typ. for 5mV overdrive ■ Pin-to-pin and functionally compatible with bipolar LM393 N DIP8 (Plastic Package) D SO-8 (Plastic Micropackage) P TSSOP8 (Thin Shrink Small Outline Package) Description The TS393 is a micropower CMOS dual voltage comparator with extremely low consumption of 9µA typ / comparator (20 times less than bipolar LM339). Similar performances are offered by the quad micropower comparator TS3702 with a push-pull CMOS output. Thus response times remain similar to the LM393.

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. Excursions of input voltages may exceed the power supply level. As long as the common mode voltage [Vicm=(Vin+ + Vin-)/2] remains within the specified range, the comparator will provide a stable output state. However, the maximum current through the ESD diodes (IF) of the input stage must strictly be observed. 4. Guaranteed by design. 5. Pd is calculated with Tamb = +25°C, Tj = +150°C and R thja = 80 °C/W for DIP14 package = 150 °C/W for SO14 package = 175°C/W for TSSOP14 package 6. Human body model, 100pF discharged through a 1.5kΩ resistor into pin of device. 7. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with no external series resistor (internal resistor < 5Ω), into pin to pin of device. Table 2.
