I have two IC chips. On one chip I have one 10K ohm pull-up resistor and on another chip I have three 10K ohm pull-up resistors.
At first I was using four through hole pull-up resistors. Then I moved to an array of SMD resistor.
Could I simplify the design by attaching all four pins of the ICs to the same pull up resistor? Should this be a 40K ohm resistor? Is this OK or is it better to attach each pin to a different resistor?
