    Thread Summary
    
                The user is experiencing excess current flow in a 128 x 128 matrix using 64 AD8113 switches after asserting RESET and UPDATE from low to high. The solution involves ensuring the shift register is fully programmed before updating the second-rank latch, and the minimum wait time between UPDATE and RESET going high is 50 ns. The issue is likely due to random data in the shift register on power-up, causing some outputs to be enabled.

    Hi ,
    
 
    We are using 64 AD8113 which is used to makes up a 128 x 128 Matrix .
    
 
    After powering up with Input ±5V , then RESET after 1 sec (L -> H) on certain condition there is excess current flow .
    
 
    Could you please let me know what are the possible condition that can be thought for this issue  .
    
 
    Thanking you 
    
 
    With best regards and wishes
