The TS556CD from STMicroelectronics is a highly versatile dual timer integrated circuit, designed to offer a robust solution for generating accurate time delays or oscillation. This IC is an extension of the popular 555 timer and incorporates two 555 timers in a single package, providing more functionality while saving space on the PCB.

Key Features

• Dual Timer Configuration: The TS556CD houses two independent 555 timer circuits, which can be used in monostable or astable modes for a wide range of applications including pulse generation, LED drivers, and more.
• Supply Voltage Range: It operates on a supply voltage range from 2V to 16V, making it suitable for various electronic applications, from low-voltage consumer electronics to industrial systems.
• High Output Current: Capable of sourcing or sinking up to 200mA, the TS556CD can directly drive loads or interface with other logic families.
• Adjustable Duty Cycle: The timers provide an adjustable duty cycle, enabling the user to fine-tune the pulse width as per the application requirements.
• Low Power Consumption: It features low power consumption, which is particularly advantageous for battery-operated devices.
• Temperature Stability: The device offers excellent temperature stability of 0.005% per °C, ensuring reliable operation under varying environmental conditions.

Applications

The TS556CD is ideal for a variety of applications, including but not limited to: timing circuits, pulse generation, sequential timing, frequency division, and as a trigger source for other ICs. Its dual nature allows for more complex timing configurations, such as pulse position modulation, without the need for additional timer ICs.

Package and Quality

Packaged in a 14-pin SOIC, the TS556CD is designed to meet the stringent requirements of the industrial and consumer markets. The device is RoHS compliant and is manufactured to STMicroelectronics' high-quality standards, ensuring both reliability and performance.
