(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 Recommended Operating Conditions table.

(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 = VDD

2 f

o (CPD + CL) where fo = output frequency, CL = output load capacitance, VDD = supply voltage

6.4 Electrical Characteristics: VDD = 2 V for TLC555C, VDD = 3 V for TLC555I

over operating free-air temperature range (unless otherwise noted)
