TLC555 in a circuit

Light output loading and a shared ground return.

TLC555CP 5V flasher: RA10k, RB68k, 10uF timing capacitor, 4.7k LED resistor, 10nF control bypass and100nF supply bypass.
The physical eight-pin package is labeled with matching net names for each connection.

Connect it, step by step

Follow the component values and pin connections

Timing network

Connect RA to VDD and RB between DISCH and the joined timing inputs.

Controls

Tie RESET HIGH and bypass CONT to ground.

Indicator

Drive the LED through 4.7 kΩ; use an external stage for heavier loads.
