DESCRIPTION
The TS556 is a dual CMOS timer which offers very
low consumption (Icc(TYP) TS556 = 200µA
Icc(TYP) NE556 = 6mA) and high frequency
(f(max.) TS556 = 2.7MHz - f(max.) NE556 = 0.1 MHz)
Thus, either in Monostable or Astable mode, tim-
ing remains very accurate.
The TS556 provides reduced supply current
spikes during output transitions, which enables
the use of lower decoupling capacitors compared
to those required by bipolar NE556.
Timing capacitors can also be minimized due to
high input impedance (1012 Ω).
