DESCRIPTION

TheTS556isa dualCMOStimerwhichoffersvery
low consumption(Icc
Icc
(f
Thus, eitherin Monostable or Astable mode, tim­ing remainsvery accurate.
The TS556 provides reduced supply current
spikes during output transitions, which enables
the useof lower decouplingcapacitorscompared
to those required by bipolarNE556.
Timing capacitors can also be minimized due to
high input impedance (10
