Programmable Timers and Oscillators

TS555CDT Description

The TS555CDT from STMicroelectronics is a 555-type single timer/oscillator IC designed for precision timing and waveform generation applications. Packaged in an 8-SOIC surface-mount format, it operates within a 2V to 16V supply range, delivering stable performance across a 0°C to 70°C temperature range. With a low supply current of 65 µA and a frequency capability of up to 2.7MHz, this IC is optimized for efficiency and versatility in embedded systems. Though marked as obsolete, it remains a reliable choice for legacy designs due to its RoHS3 compliance and REACH-unaffected status.

TS555CDT Features

• Low Power Consumption: 65 µA supply current extends battery life in portable applications.
• Wide Voltage Range (2V–16V): Supports diverse power environments, from low-voltage IoT devices to industrial systems.
• High Frequency (2.7MHz): Enables rapid timing cycles for PWM, pulse generation, and clocking.
• Surface-Mount (SOIC-8): Compact footprint ideal for space-constrained PCBs.
• Robust Compliance: Meets RoHS3 and REACH standards, ensuring environmental and safety adherence.
• Moisture Sensitivity Level 1 (MSL1): Suitable for extended storage and handling without dry packing.

TS555CDT Applications

• Precision Timing: Used in delay circuits, pulse-width modulation (PWM), and one-shot timers.
• Oscillator Circuits: Generates clock signals for microcontrollers or frequency-sensitive systems.
• Consumer Electronics: Powers timing functions in toys, LED flashers, and small appliances.
• Industrial Control: Acts as a watchdog timer or event sequencer in automation systems.
• Legacy Designs: Ideal for maintaining or repairing older equipment where newer alternatives are incompatible.

Conclusion of TS555CDT

The TS555CDT excels in low-power, high-frequency timing applications, offering a balance of performance and reliability. While obsolete, its wide voltage range, compact packaging, and compliance certifications make it a pragmatic choice for specific use cases. Engineers working on battery-operated devices, industrial controls, or retrofit projects will find its specifications well-suited to demanding timing requirements. For new designs, consider modern alternatives, but for legacy support, the TS555CDT remains a proven solution.
