† Full range is 0°C to 70°C for the TLC555C and −40°C to 85°C for the TLC555I. For conditions shown as MAX, use the appropriate value specified
in the recommended operating conditions table.
NOTE 2: These values apply for the expected operating configurations in which THRES is connected directly to DISCH or to TRIG.
