Definitely if they say use 40K or less that would be the right thing to
do. I didn't look at the data sheet for the '4550 when I said 47K, it's
a value that I have used based on the leakage current spec and wanting
to keep the resistor as high as possible. But I had not seen the part of
the data sheet you mentioned. Thanks for finding it.

Cheerful regards,
