DESCRIPTION
The TS555 is a single CMOS timer which offers
very low consumption (I
V
frequency f
NE555 = 0.1 MHz)
Thus, either in Monostable or Astable mode, tim-
ing remains very accurate.
The TS555 provides reduced supply current
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
