The TS556CN is a dual precision timing circuit in an 8-pin DIP package, which is primarily used for generating stable and accurate timing signals in a variety of applications. It is a part of the TS556 series of low-power CMOS timers produced by STMicroelectronics. The IC offers several key features that make it highly versatile and suitable for a wide range of timing applications.
One of the primary features of the TS556CN is its ability to operate in a wide range of power supply voltages, from 2V to 16V. This ensures compatibility with different power supply sources, making it a flexible choice for various electronic systems. Moreover, the IC has a low power consumption, making it ideal for battery-powered devices or applications where energy efficiency is essential.
The TS556CN incorporates two independent precision timing sections, each consisting of a voltage comparator, a relaxation oscillator, and an output stage. This dual configuration allows for the simultaneous generation of two separate timing signals, greatly enhancing its applicability. Additionally, the IC supports a wide range of timing intervals, from microseconds to several hours, making it extremely versatile.
Another notable feature of the TS556CN is its ability to operate in various timing modes, including monostable (one-shot) and astable (free-running) modes. In the monostable mode, the output signal remains high for a fixed duration determined by external resistors and capacitors, providing a pulse or delay effect
