SN74AVCB164245: Maximum Data Rates

Part Number: SN74AVCB164245
Other Parts Discussed in Thread: SN74AVC16T245,

I would like to know the maximum data rate for this device.

For other dual-supply bus tranceiver (SN74AVC16T245 for example), i found some information for different supply voltages.

I would like to shift Data signals with maximum data rate of 80 Mbps. Is that possible with this device for any supply voltage?

    Hi Christoph,

    Although the max data rate supported by this device is not specified on the datasheet, I am certain that the 80Mbps datarate can be supported.
    Is there a reason to not consider using the sn74AVC16T245 device?

    Hi Shreyas,

    thank you for your answer.

    Well, it seems, that the SN74avcb164245 has lower output currents than the SN74avc16t245. At the moment, we use the SN74avc16t245. This device is very fast and we have some EMC problems. So i searched for dual supply transceiver with lower speed, but speed enough for 80 MHz.

    Are there some reasons for not taking the SN74avcb164245?

    I only see, that the propagation delay is slightly higher, but i can live with that.

    Best regards

    Hi Christoph,

    From the product folder of the SN74AVCB164245, I see that the frequency is 100Mhz max.

    Because of the dynamic output impedance control circuitry, the EMC should be significantly reduced.
