The TLC556CN from Texas Instruments is a dual LinCMOS timer IC designed for versatile timing and oscillation applications. It operates at frequencies up to 2.1MHz and supports single-supply operation from 2V to 18V.
This timer IC offers very low power consumption, typically 2mW at VDD = 5V, making it suitable for power-sensitive designs. The CMOS output is capable of swinging rail-to-rail and provides high output current capability, sinking up to 100mA and sourcing 10mA. It is functionally interchangeable with the NE556 and features the same pinout.
The TLC556CN is housed in a 14-DIP package and supports through-hole mounting. Its high input impedance allows for smaller timing capacitors compared to the NE556, enabling more accurate time delays and oscillations. The device is compatible with CMOS, TTL, and MOS logic levels.
Key electrical characteristics include a supply current of 720 µA typical and an operating temperature range of 0°C to 70°C. The trigger level is approximately one-third of the supply voltage, and the threshold level is approximately two-thirds, adjustable via the control voltage pin.
