Overview
The TS555CN, produced by STMicroelectronics, is a low-power single CMOS timer that offers significant improvements over traditional bipolar timers like the NE555. It is characterized by its very low power consumption, high frequency capabilities, and reduced supply current spikes during output transitions. This component is pin-to-pin functionally compatible with the bipolar NE555, making it an excellent alternative for applications requiring lower power and higher frequency stability.
