(1) Full range is 0°C to 70°C the for TLC555C, and –40°C to +85°C for the TLC555I. For conditions shown as MAX, use the appropriate value specified in the Section 5.3.
(2) These values apply for the expected operating configurations in which THRES is connected directly to DISCH or to TRIG.
(3) CPD is used to determine the dynamic power consumption.
(4) PD = VDD2 fo (CPD + CL) where fo = output frequency, CL = output load capacitance, VDD = supply voltage.
