Description
The TS555 is a single CMOS timer with very low
consumption:

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.

1. Short-circuits can cause excessive heating. These values are typical and specified for a four layers PCB.
2. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
3. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins remain floating.
4. Charged device model: all pins plus package are charged together to the specified voltage and then
discharged directly to the ground.
