MOS
Description
The TS556 is a dual CMOS timer which offers a
very low consumption:
(I
cc(TYP)
TS556 = 220 µA at V
CC
= 5 V versus
I
cc(TYP)
NE556
(a)
= 6 mA),
and high frequency:
(f
(max.)
TS556 = 2.7 MHz versus
f
(max.)
NE556
(a)
= 0.1 MHz)
In both monostable and astable modes, timing
remains very accurate.
The TS556 provides reduced supply current
spikes during output transitions, which enables
the use of lower decoupling capacitors compared
to those required by bipolar NE556
(a)
.
Due to the high input impedance (10
12
Ω), timing
capacitors can also be minimized.
