Other Parts Discussed in Thread: SN74AUC245

Dear Team,

Could you help to recommend the signal buffer solution which is based on the below requirement?

1. 8 bit.

2. Bi-directional

3. For 5V tolerant LVTTL signal.

4. Data rate up to 1 Gbps.

5. The buffer DC spec suggest to meet below.

Thank you.

    Hi Jim,
    The logic group doesn't have a device that can support 1 Gbps (I believe our fastest devices (AUC family) top out around 300 MHz.

    I'm not sure who to contact for you in the high speed group - you might try posting to their forum.

    Hi Emrys,

    After confirm with the customer, they can accept the solution which support up to 300MHz.
    So could you provide your recommendation?

    Thank you.

    The fastest 8-bit transceiver we have (300MHz) is the SN74AUC245, however its maximum voltage is only 3.6V.

    The fastest 5V device I know of is in the AHC family, but that caps out around 75-100MHz. The LVC1G series of devices do support ~100MHz and 5V, but only come in 1 to 3 bit versions.

    Can you tell me about the application that requires such high speed 5V signals?
