TS393
Micropower Dual CMOS Voltage Comparators

Extremely low supply current: 9a 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: 1012 typ Fast response time: 2.5s typ. for 5mV overdrive Pin-to-pin and functionally compatible with bipolar LM393 P TSSOP8 (Thin Shrink Small Outline Package) D SO-8 (Plastic Micropackage) N DIP8 (Plastic Package)

Description
The TS393 is a micropower CMOS dual voltage comparator with extremely low consumption of 9A 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.

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. 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 = +25C, Tj = +150C and R thja = 80 C/W for DIP14 package = 150 C/W for SO14 package = 175C/W for TSSOP14 package 6. Human body model, 100pF discharged through a 1.5k 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 < 5), into pin to pin of device.
