DESCRIPTION
The TS555 is a single CMOS timer which offers
very low consumption (Icc
(TYP)
TS555 = 100µA
Icc
(TYP)
NE555 = 3mA) and high frequency
(f
(max.)
TS555 = 2.7MHz - f
(max.)
NE555 = 0.1MHz)
Thus, eitherin Monostable or Astablemode,timing
remains very accurate.
The TS555providesreducedsupplycurrent spikes
during output transitions, which enables the use of
lower decoupling capacitors compared to those
required by bipolar NE555.
Timing capacitors can also be minimized due to
high input impedance (10
12
Ω).
