SN74LVC1G3157-Q1: Change in datasheet absolute max rating of select and I/O pin

Part Number: SN74LVC1G3157-Q1
Other Parts Discussed in Thread: SN74LVC1G3157

Hi team,

I found a change in absolute max rating value of Select pin (VIN) and VI/O pin in the datasheet.

Could you please double check if this change is correct? 

  1. December 2021 SCES463H datasheet. power off protection is available for VIN only.

2. June 2025 SCES463I datasheet. power off protection is available for VI/O only.

    That change indeed is wrong. The Revision History says "Changed ABS max VCC and VI/O voltage", and this description is correct, i.e.. only these two entries should have been changed.

    Apparently, the table was copied from some LVC logic device (which would have inputs and outputs, but not switch I/Os), and not all cells were adjusted correctly.

    The SN74LVC1G3157 (without -Q1) datasheet shows the correct values.

    Hi Clemens-san,

    That makes sense. Thank you for your prompt reply. 

    Let me double check that below ABS spec for DCK package from non Q1 datasheet is the correct value 

    for DCK package Q100 device, correct?

    Please consider to change the datasheet description soon.

    regards,

    Hi Shinji,

    Thank you for bringing this to our attention.

    I will see if we currently have a request to change the datasheet.

    Thank you,
    Arya
