Good Morning,

I'd like to use TLC555 <http://www.ti.com/product/TLC555> for an
application which requires an operating temperature range of -40°C to
85°C.

I didn't undertstand if I could use a 3.3V single-supply with package -QD
(part number TLC555QDRQ1).

On datasheet (http://www.ti.com/lit/ds/symlink/tlc555-q1.pdf) it's shown
in table that VDD from 5V to 15V occurs to supply this component; but on
the same datasheet, there is an other table where it's shown that I can
supply this component with a VDD from 2V-to 15V.

Can I use a VDD = 3.3V as single-supply of TLC555QDRQ1 or do I have to
choose another package?

Thanks.

Best regards

It depends on which specs you use:

Military Specs (Q or M), 5V is min.
Industrial Specs (I), 3V is min,
Consumer specs(C) , 2V is min.
for Vdd.
