TS555
Low-power single CMOS timer
Datasheet -production data 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), SO8
(plastic micropackage) and high frequency:
(ff(max.) TS555 = 2.7 MHz versus
f(max) NE555(a) = 0.1 MHz). Pin connections

9ROWDJH 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. Features
• Very low power consumption:
– 110 µA typ at VCC = 5 V
– 90 µa typ at VCC = 3 V …
