(2) The maximum total current IOLmax, for all outputs combined, should not exceed 12 mA to hold the maximum voltage drop specified. (3) The maximum total current, IOHmax, for all outputs combined, should not exceed 48 mA to hold the maximum voltage drop specified. 4 Submit Documentation Feedback Copyright © 2010, Texas Instruments Incorporated Product Folder Link(s) :UCD90910 |
