Hello,
We consider to use 555 for clock generation. LMC555 25C power supply current is written in datasheet.
Could we know the maximum power supply current at 125C. We want to compare power supply current between TLC555I and LMC555 at 3.3V.
We need to care about power consumption.
Best regards,
Toshihiro Watanabe
Toshihiro-san,
I can't speak for maximum supply current for 3.3V, but I can supply sample data below.
At 3.3V LMC555 supply current is just under TLC555.
At 2V supply there is no difference, but at 15V supply LMC555 is clear winner.
LMC555 Is vs Vdd
TLC555 Is vs Vdd
This data is for DC or low frequency.
The Cpd for 3.3V clocking power dissipation was 43pF for LMC555 and 103pF for TLC555
