STMicroelectronics TS CMOS Dual Timer 2 Internal Timers 14-Pin SO Package TS556IDTTR

STMicroelectronics TS556IDTTR is a dual CMOS timer integrated circuit designed for precise timing control in electronic circuits. Featuring two internal timers, it supports both monostable and astable modes, delivering accurate timing with low power consumption. Operating over a wide voltage range of 2 to 16 volts, this timer typically consumes only 220 microamps at 5 volts supply, making it suitable for power-sensitive applications.

The device's high input impedance of 1012 ohms allows for reduction in timing capacitor sizes, and it minimizes supply current spikes during output transitions, enabling more stable circuit operation. Its output is compatible with TTL, CMOS, and logic MOS devices, providing broad integration possibilities.

With an extended operating temperature range of -40°C to 125°C, the TS556IDTTR is suited for various industrial and commercial applications including clock generation, timing delays, and pulse width modulation in electronic control systems.

The compact 14-pin SO package measures 8.75 mm in length and 1.65 mm in height, facilitating space-efficient circuit designs. This timer IC is pin-to-pin compatible with the bipolar NE556 series, offering an upgrade path with improved power efficiency and higher frequency capabilities up to 2.7 MHz.

Contains 2 internal timers for dual functionality. Wide supply voltage range from 2 V to 16 V supports diverse power scenarios. Low typical supply current (~220 μA at 5 V) conserves energy in applications. High input impedance allows for smaller timing capacitors.

Reduced supply current spikes aid in stable output transitions. Output compatible with various logic family devices. Operates reliably between -40°C and 125°C for industrial use. Compact 14-pin SO package supports space-restricted PCB layouts.

Pin compatible with existing NE556 timer ICs for easy replacement.

This STMicroelectronics CMOS timer IC is ideal for use in industrial automation, electronic instrumentation, and embedded system timing. Its energy-efficient design and accurate timing reliability make it a preferred choice for demanding timing and control circuits across power and electronic sectors.
