Impossible Oscillator
The ELM460 is a complete astable oscillator
circuit in an 8 pin package. The circuit (impossibly!)
requires no external components to operate, as all
timing is generated internally.
Immediately after power-up, the ELM460 begins
to oscillate continuously at a frequency determined
by the logic levels on the configuration inputs. At the
end of every period, the circuit again reads these
configuration settings, and automatically adapts to
any changes that are made.
Two outputs are provided, an active high output
and it’s logical inverse. The circuit output is always a
50msec pulse, independent of the time period
selected.
