Part Number: SN74AVC16827
Other Parts Discussed in Thread: SN74AUC244

Hi,

Could you please tell me the 100MHz and 200MHz operating conditions for SN74AVC16827 ?
* e.g.: VCC, CL(output load capacitance, etc)

Best regards,
Kato

    Kato San,

    What is the application requirement? I would not beleive that the device can reach up to 200Mhz frequency.

    In general, higher frequency supports higher data rates. Lower the loading cap, higher is the frequency supported.

    Hi Shreyas-san,

    Thank you for your reply.

    I found the operating specification on the following website, so I asked you that.
    Please tell me the maximum output load capacitance when working at VCC = 1.8V and 100MHz frequency if SN74AVC16827 cannot reach up to 200MHz frequency.
    In addition, could you please suggest another solution that meets the above conditions ?

    Kato-san,

    consider using the AUC244 or the SN74AUC244 buffer which can support 1.8V at 200Mhz.

    we can guarantee the drive strength but cannot tell the maximum load capacitance the device can tolerate while working at a frequency.

    The max cap will also be limited by the rise time required by the application. higher the cap loading, the slower the rise time which will affect the max freq.

    Hi Shreyas-san,

    Thank you for the information.

    I understood and will contact you if I get additional questions from our customer.

    Best regards,
