Dear sir,

A quick question of ISO7763FDWR and ISO6763FDWR:

Customer want to use the pull-up  4.7k ohm resistors  on Pin 7/ Pin 10 of ISO7763FDWR and ISO6763FDWR,  any risk for this?

Background:  customer want to do the 2nd source compatible design in new project,  which is the Enable Pin of  the main source now.

Nice day!

    Hi Jack,

    Thanks for reaching out.

    Connecting a 4.7kΩ pull-up resistor for an input or output pin isn't an issues including the pins 7 and 10 of both ISO7763 and ISO6763. Hence, customer can go ahead with these devices as 2nd source in their design without any concerns. Thanks.
