    You're welcome! *8)

    ...hmmmmm, the website was last updated 1/17/2009?

    Might try giving them a call directly. If business is slow, the website/email may not be monitored too closely.

    Dear davejames:

    It seems that I could not contact with proteanlogic. Is proteanlogic really exist?
    Do you know is there any chip which can replace RSB509B?
    Please help me out?

    I called the company and left a voice mail as to current stock on the chip in question. Will let you know if they call back.

    Hi amitof,

    I have no experience with the RSB509B or any possible replacements. I was just passing on the info I gleaned from an interweb search.

    Have you called Proteanlogic? Not email. Called, with a phone.

    Yes, I have called Proteanlogic several times, but no answer.
    I use RSB509B as a serial buffer IC. The MCU which I have used in the program is BS2sx.

    try digikey Phone:1-800-344-4539, if you have the datasheet for it, you can give their tech department a good description, and they can source a identical one for you. I've had to do that in the past trying to get obsolete parts, and they have never not found it.

    Just spoke with them a few days ago & ordered a dozen 509B chips. They indicated they are extremely busy, but are still producing & supplying the buffers.

    Good to hear.

    Just wish they would have returned my phone calls and emails.
