Hai, please review the design and kindly send back the review comments

  • Hi,

    Can you let me know signal levels on 1, 7 and 8?

    Please note that pins 1, 7 and 8 cannot go below 0V and above VDD. Otherwise schematics looks fine to me. I cannot comment unless I know the signals connected to 1, 7 and 8.

    Also protection diodes limit the voltage compliance at terminal H, terminal L, and terminal W, making it important to power up VDD first before applying any voltage to terminal H, terminal L, and terminal W. The diodes are forward-biasing,meaning VDD is not powered first.The ideal power up sequence is VDD, digital inputs,and VH, VL, and VW. The order of powering digital inputs,VH, VL, and VW does not matter as long as they are powered after VDD

    Regards,
