General Description

The TS555 is a single CMOS timer with very low consumption: I(cIccc(T(TYYPP) )NTES555555(a=) 110 µA at = 3 mA), VCC = +5 V versus and high frequency: (f(fmf(maxa)xN.) TES55555(5a)==20.7.1MMHHzzv).ersus Timing remains accurate in both monostable and astable mode.

The TS555 provides reduced supply current spikes during output transitions, which enable the use of lower decoupling capacitors compared to those required by bipolar NE555(a).

With the high input impedance (1012Ω), timing capacitors can also be minimized.
