LM555: Time Delay device recommend

Part Number: LM555
Other Parts Discussed in Thread: TLC555

Hi team,

My customer want a time delay device.

Clock signal :6.25MHz

delay: 30ns

Could you please recommend one?

Thanks,

Brian

  • Hello Brian, 

    None of the 555 timers will operate at this frequency. The TLC555 is the fastest device and ranges from 1.2 to 2.1 MHz. Propagation delays start to impact the 555 timers beyond 100 kHz operation. I am not sure a 555 timer device is the best option for this application. A microcontroller may be a better fit. 

    Best Regards,
