DESCRIPTION

The TS555 is a single CMOS timer which offers

very low consumption (Icc(TYP) TS555 = 100

µA

Icc(TYP) NE555 = 3mA) and high frequency

(f(max.) 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 (10

12 Ω).
