The TS556IDT from STMicroelectronics is a dual 555-type timer/oscillator IC designed for precision timing and oscillation applications. Packaged in a 14-SOIC surface-mount form factor, it operates within a 2V to 16V supply range, making it versatile for both low-voltage and standard industrial applications. With a 2.7MHz frequency capability and a low 130 µA supply current, it balances performance and power efficiency. The device is RoHS3 compliant and REACH unaffected, ensuring adherence to environmental regulations. Though marked as obsolete, it remains a reliable choice for legacy designs requiring stable timing solutions.
The TS556IDT excels in:
The TS556IDT offers a robust, dual-timer solution with wide voltage compatibility, low power draw, and high-frequency performance. While obsolete, its reliability and compliance make it a pragmatic choice for engineers maintaining or designing systems requiring precise timing. Its compact SOIC package and dual functionality provide a space-efficient alternative to discrete timers, particularly in industrial and consumer applications.
