The TS556CN from STMicroelectronics is a versatile dual timing device that can provide two independent timing circuits within a single package. This IC is a high-performance version of the standard 555 timer, offering reduced power consumption and increased stability over a wide range of operating voltages and temperatures. The TS556CN is widely used in a variety of applications, from simple time delay circuits to complex sequential systems.

Key Features

• Supply Voltage Range: The TS556CN operates on a supply voltage range from 4.5V to 16V, making it suitable for a wide array of electronic applications.
• Dual Timers: It contains two independent 555 timers, which can be used in astable or monostable modes for generating accurate time delays, pulse generation, or oscillation.
• Low Power Consumption: The device is designed for low power consumption, drawing typically 220 μA at VCC = 5V, which is ideal for battery-operated devices.
• High Output Current: Capable of sourcing or sinking up to 200 mA, allowing it to drive relay coils, LED displays, and other output devices directly.
• Adjustable Duty Cycle: The output waveforms can have their duty cycle adjusted by varying the resistance and capacitance values connected to the timer.
• Temperature Stability: The TS556CN maintains stable timing over a temperature range from -40°C to +85°C.

Applications
