Description
The TS555 is a single CMOS timer with a very
low consumption:
(I
TS555 = 110 µA at V

I
NE555 = 3 mA),
cc(TYP)
and high frequency:
(f
TS555 = 2.7 MHz versus
f(max.)
f
NE555 = 0.1 MHz).
(max)
Timing remains accurate in both monostable and
astable mode.
The TS555 provides reduced supply current
spikes during output transitions, which enable the
use of lower decoupling capacitors compared to
those required by bipolar NE555.
With the high input impedance (10
capacitors can also be minimized.
