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.
Very low power consumption:
220 μA typ at VCC= 5 V
180 μA typ at VCC= 3 V
High maximum astable frequency 2.7 MHz
Pin-to-pin and functionally compatible with bipolar NE5561
Wide voltage range: 2 V to 16 V
Supply current spikes reduced during output transitions
High input impedance: 1012Ω
Output compatible with TTL, CMOS and logic MOS
