DESCRIPTION
The TS555 is a single CMOS timer which offers
very low consumption (I_cc(TYP) TS555 = 110µA at
V_CC=+5V versus I_cc(TYP) NE555 = 3mA) and high
frequency f_f(max.) TS555 = 2.7MHz versus f_(max.)
NE555 = 0.1 MHz)
Thus, either in Monostable or Astable mode, tim-
ing 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 (10¹²â„¦).
