THE FASTEST 555 OSCILLATOR Circuit
The highest frequency can be
obtained by connecting the output to pins 2 and 6. This arrangement
takes about 5mA and produces an output as shown:
View the output on a CRO. Our
555 "Test Chip" produced a frequency of 300kHz at 5v and 12v.
(CMOS versions will operate at a higher frequency.) Note the very
short LOW TIME.
