DESCRIPTION

The TS556 is a dual CMOS timer which offers

very low consumption (I

cc(TYP) TS556 = 220µA at

VCC=+5V versus Icc(TYP) NE556 = 6mA) and high

frequency f

f(max.)

TS556 = 2.7MHz versus f

(max.

)

NE556 = 0.1 MHz)

Thus, either in Monostable or Astable mode, tim-

ing remains very accurate.

The TS556 provides reduced supply current

spikes during output transitions, which enables

the use of lower decoupling capacitors compared

to those required by bipolar NE556.

Timing capacitors can also be minimized due to

high input impedance (1012

Ω).
