DESCRIPTION

The TS555 is a single CMOS timer which offers
very low consumption (Icc
Icc
(f
Thus,eitherinMonostableorAstablemode,timing
remainsvery accurate.
The TS555providesreducedsupplycurrentspikes
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
