Hello,
We are seeing a failure where the selector lines A, B, and C are latching permanently. We typically cycle through various inputs to monitor voltages across our system. However, we are seeing a number of units exhibiting a behavior where the value is the same across all channels.
We were able to isolate it to the MUX and not the micro.
We have some additional failed boards on their way back to us to examine, but were hoping you might be able to help us understand what might cause the SN74LV4051ADR MUX to latch?
Thanks!!!
