Low power single CMOS timer

Description

The TS555 is a single CMOS timer with very low consumption: (Icc(TYP)TS555 = 110 μA at VCC= +5 V versus Icc(TYP)NE555(a)= 3 mA), and high frequency: (ff(max.)TS555 = 2.7 MHz versus f(max)NE555(a)= 0.1 MHz). 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.
