Part Number: NE555
At present, when using ne555 to drive MOS behind the small power LED, using switching power supply, ne555 works normally, put on the battery (lithium battery / carbonic acid) battery voltage test 13.5v. This time has been powered and the battery voltage will be down to 1v, off Turn on the battery voltage measurement, or 13,5v, disconnect the battery on the foot, the battery voltage is normal, please help confirm what is the reason Is ne555 CMOS or ttl? When reading 5v input, it is written as ttl level. Please help confirm whether the wide voltage input is cmos. Is the internal integrated transistor just ttl level? Both power modes are normal using tlc555
