The TLC555CDR is a CMOS timer with support products manufactured by Texas Instruments. It features low-power consumption, wide operating-voltage ranges, and high output-current drive capability. The device has a 16-pin dual-in-line package with an adjustable duty cycle. It offers two operating modes, monostable and astable, and the timing can be controlled externally by two resistors and one capacitor. The circuit is used for oscillation and timing applications. It also offers an ultra-stable amplitude control. The TLC555CDR is suitable for use in applications such as non-volatile storage devices, modem applications, serial communication links, laser diode drivers, token-ring networks, and in security and alarm systems.
