STMicroelectronics TS555
The TS555 is a single CMOS timer with very low consumption: (Icc(TYP) TS555 = 110 µA at VCC = +5 V versus Icc(TYP) NE555(a) = 3 mA), and high frequency: (ff(max.) TS555 = 2.7 MHz versus f(max) NE555(a) = 0.1 MHz). 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.| Part No. | TS555 |
