DESCRIPTION

The TS556 is a dual CMOS timer which offers very low consumption (Icc(TYP) TS556 = 220µA at VCC=+5V versus Icc(TYP) NE556 = 6mA) and high frequency ff(max.) TS556 = 2.7MHz versus f(max.) NE556 = 0.1 MHz) Thus, either in Monostable or Astable mode, timing 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 (1012Ω).
