TS556IDTTR Datasheet PDF - ST Microelectronics

●The TS556 is a dual CMOS timer which offers a very low consumption: (Icc(TYP)TS556 = 220 μA at VCC = 5 V versus Icc(TYP) NE556(a)= 6 mA),

●and high frequency:(f(max.)TS556 = 2.7 MHz versus f(max.)NE556(a)= 0.1 MHz)

●In both monostable and astable modes, 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(a).

●Due to the high input impedance (1012 Ω), timing capacitors can also be minimized.
