Full range is 0°C to 70°C for TLC555C, −40°C to 85°C for TLC555I, −40°C to 125°C for the TLC555Q, and −55°C to 125°C for TLC555M. 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 TRIG.
