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
