Dual 555-type timer in 14-SOIC — supply range and frequency ceiling
The TLC552CD is a dual 555-type timer/oscillator from Texas Instruments' LinCMOS™ series, delivering two independent timing channels in a single 14-SOIC package (0.154" wide, 3.90 mm body). Maximum oscillation frequency is 2.8 MHz, with a typical supply current of 1.6 mA — the CMOS construction keeps quiescent draw low compared to bipolar 555 variants, which matters for battery-powered or thermally constrained boards.
