Hallo guys...
I was wondering what is the exact replacement of the LM3909 after the discontinuing of its production. The famous LM3909 had the ability to work and actually to get all of the juices of a single alcalic cell (1,5) and continuing working after the cell droped under the 0,50V for more than 12 months of full working.
Some people saying what we need the old and expensive 3909 when we do the same job with the 555. But there always some deferences:
first of all and correct me if I am wrong the functional range of the 555 starts in 4,5V and gets ideal in 6V and 12V. Instead the old aged 3909 had all its abilities in 1,5V!!!
Also the old chip had a very well regulated and stable time of oscillating.
Have anyone any idea what's the replacement of this? If i had to build a flasher light with the LM3909 i would need just the IC, the led, the resource and the capacitor. That's all!!!
Somebody told me why don't you make an analogue of the IC using the appropriate parts. The answer is obvius: If i had the appropriate space i would do it. But when you have to build an SOS navy flasher in the dimensions of a common flasher then there's no any available space.
Please any recommendation is welcome
PS.....what was the company made that ICs?????
