TS555 = 2.7MHz - f(max.) NE555 = 0.1 MHz) Thus, either in Monostable or Astable mode, timing 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 (1012 ).
