  • Is it essential that CTS/DSR are both pulled high before power is applied? Is it sufficient if they are pulled high from the same supply voltage, therefore only pulled high as power is applied???

    I am tossing up between the ADH8066 and the SM5100B, prefer the ADH8066 as it has sim on-board which means less discrete components and less board space, however I have already used the SM5100B successfully and it didn’t seem to care about logic levels on pins before power was applied.

No public wish lists :(
