The TLC551CD is a 555-type timer/oscillator from Texas Instruments, configured as a single timer in an 8-SOIC package. It operates from a 1V to 15V supply and draws 360 µA typical supply current — a low-power figure that suits battery-powered or energy-conscious designs. Maximum oscillation frequency is 1.8 MHz, and the device is rated for the commercial temperature range of 0°C to 70°C. The 8-SOIC footprint (0.154-inch width, 3.90 mm) is a standard surface-mount package for general-purpose PCB integration.
