TS393

Micropower dual CMOS voltage comparators

Features

■Extremely low supply current: typically 9 µA per

comparator

■Wide single supply range 2.7 V to 16 V or dual

supplies (±1.35 V to ±8 V)

■Extremely low inp ut bias current: 1 pA typical

■Extremely low input offset current: 1 pA typical

■Input common-mode voltage range includes

ground

■High input impedance: 1012 Ω typ

■Fast response time: 2.5 µs typ. for 5 mV

overdrive

■Pin-to-pin and functionally compatible with dual

bipolar LM393

Description

The TS393 is a micr opower CMOS dual voltage

comparator with ex tremely low consumption of

9 µA typically per comparator (20 times less than

the dual bipolar LM393). Similar performance is

offered by the dual micropower comparator

TS3702 with a push-pull CMOS output.

Thus response times remain similar to t he LM393.

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.

HBM: human body model(6)

6. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a

1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations

while the other pins are floating.

MM: mach ine model(7)

7. Machine model: A 200 pF capacitor is charged to the specified voltage, then discharged directly between

two pins of the device with no external series resistor (internal resistor < 5 Ω). 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.

4 Package information

In order to meet environmental requirements, ST offers these devices in ECOPACK®

packages. These packages have a lead-free second level interconnect. The category of

second lev el interconnect is marked on the package and on the inner box label, in

compliance with JEDEC Standard JESD97. The maximum ratings related to soldering

conditions are also marked on the inner box label. ECOPACK is an ST trademark.

ECOPACK specifications ar e available at: www.st.com.
