HI,

PDN #20230621002.3 stated that pn in the subject is a pin for pin replacement for pn ISO7240ADW. However the voltage is different is this correct?

Thank you,

    Hello,

    Thanks for your question.

    If you mean supply voltage, yes it is different.

    The ISO7240A device supports a recommended supply voltage of 3.15-5.5V. The ISO6740 supports 1.71V-1.89V and 2.25V-5.5V.

    Since the ISO6740 has a wider supply voltage range, the same supply voltage used for ISO7240A should work for the ISO6740.

    Hope this helps.
