■ WIDE SINGLE SUPPLY RANGE
2.7V TO 16V OR DUAL SUPPLIES
(±1.35V TO ±8V)
■ EXTREMELY LOW INPUT BIAS CURRENT :
1pA typ
■ EXTREMELY L OW IN PUT OF F SET
CURRENTS : 1pA typ
■ INPUT COMMON-MODE VOLTAGE RANGE
INCLUDES GND
■ HIGH INPUT IMPEDANCE : 10

Ω typ
■ FAST RESPO NSE TIME : 2.5µs typ for
5mV overdrive
■ PIN-TO-PIN AND FUNCTIONALLY
COMPATIBLE WITH BIPOLAR LM393
DESCRIPTION
The TS393 is a micropower CMOS dual voltage
comparator with extremely low consumption of
9µA typ / comparator (20 times less than bipolar
LM393). Similar performances are offered by the
dual micropower comparator TS3702 with a
push-pull CMO S outpu t.
Thus response times remain similar to the LM393.

1. All volta ge values, except differential voltage, are w i th respect to network grou nd t erminal.
2. Differe nt i al voltages are the non-i nverting i nput termi nal with respect to the inverting input terminal .
3. Excursion s of input voltages may exceed the power supply leve l . As long as the common m ode voltage [V
within the specified range, the comparator will pr ovide a stable ou tput state. H owever, the maximum cur rent throu gh the ESD diode s (if)
of the input stage must st ri ct l y be observ ed. The output m ust never ex ceed the pow er supply voltage.
