8.3 Power Supply Recommendations

The LMC555 requires a voltage supply within 1.5 V to 15 V. Adequate power supply bypassing is necessary to protect associated circuitry; the minimum recommended is 0.1 μF in parallel with 1-μF electrolytic. Place the bypass capacitors as close as possible to the LMC555 and minimize the trace length.
