5 Description (continued)
The advantage of the TLC555-Q1 is that it exhibits greatly reduced supply-current spikes during output
transitions. Although the CMOS output is capable of sinking over 100 mA and sourcing over 10 mA, the main
reason the TLC555-Q1 is able to have low current spikes is due to its edge rates. This minimizes the need for
the large decoupling capacitors required by the NE555.
The TLC555-Q1 is characterized for operation over the full automotive temperature range of –40°C to 125°C.
