Description
The TS555 is a single
CMOS timer with very low consumption:
I(cIccc(T(TYYPP) )NTES555555(a=)
110 µA at = 3 mA),
VCC
=
+5
V
versus
and high frequency:
(f(fmf(maxa)xN.) TES55555(5a)==20.7.1MMHHzzv).ersus
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(a).
With the high input impedance (1012Ω), timing
capacitors can also be minimized.
