TLC556MDG4

The TLC556MDG4 from Texas Instruments is a dual timer integrated circuit belonging to the 555 type family. This device is designed for general-purpose timing and oscillation applications, offering a wide operating voltage range from 5V to 18V and capable of operating at frequencies up to 2.1MHz.

Key electrical characteristics include a typical supply current of 720 µA and a typical supply current of 0.13 mA. The output can sink up to 100mA and source 10mA. The operating temperature range is -55°C to 125°C, making it suitable for various environmental conditions.

This timer IC is available in a 14-SOIC surface mount package, with dimensions of 8.65 mm × 6 mm and a package size of 51.9 mm². It is functionally interchangeable with the NE556 and shares the same pinout. The device features low power consumption and CMOS output capable of swinging rail to rail.

Designed for compatibility with CMOS, TTL, and MOS logic, the TLC556MDG4 is a versatile component for timing circuits. Its high input impedance allows for smaller timing capacitors compared to the NE556, enabling more accurate time delays and oscillations.
