Hi Team, I would like to confirm if there is any information about the minimum permissible pull up current for the DAC53608 clear pin?
Thank you in advance.

You can calculate the following formula to calculate pull up value for CLR pin.
R pull-up = (V supply – VH(min)) / Isink
Here Isink can be anywhere between say 500uA to 10mA( max). 10mA is max value since current into any digital pin cannot exceed this value as per datasheet.
for example with Vsupply as 5V and Isink = 1mA, Rpull-up = (5-2.4)/1mA = 2.6K
VIH ( min) is 2.4V from datasheet.
