SN74AVC32T245: Channel to Channel Skew

Part Number: SN74AVC32T245


Hi team,

Customer must need 1.8V to 3.3V level shifter on 8bit paralel signal. Since the application is paralel interface the skew ch to ch skew is critical for communication. To consider the switching characteristics, the delays are 4.4ns max, 0.5ns min. That results in 3.9ns which isn't accepted if the variation is channel to channel. It is hoped that this variation is device to device variation.

Please let me know suitable device if it doesn't fit the application.

  • Hello Hayashi,

    Since this part was released back in 2004, I'm unable to look at the validation data.

    The 0.5ns is not correct and generally is added to the minimum column since we cannot put a zero.

    Please look at the answer from Nirav on this E2E post. It notes the typical max skew for AVC devices will be 250ps.

    Regards,

    Josh
