Hello E2E Community:
In one of our designs we are currently using TI part SN74AUC74RGYR, which is a dual positive-edge-triggered D-type Flip Flop and was wondering if you know of any applications that use this part. In our circuit, when the unit is hot (between 70-90 Degrees Celsius) we seem to be having a problem when the voltage level of VCC/(PR not) drops down below around 2.0V it makes it so the outputs no longer toggle and seem to lock up because maybe it is not able to drive the load after the part or something else. I was wondering if you have any insight on the part or heard of any issues similar to this?
Figure 1: Pink and Green are Q and 'Q not' on one side of the SN74AUC74RGYR part and in this picture Blue and cyan represent the output that is to be driven after the part. So when the signals disapear so is our output.
Figure 2: Blue is the VCC/PR not, Cyan represents the 'CL not' (so when it goes high, the part is suppose to toggle), and green represents the output but is also suppose to start when cyan goes high.
Thank you,
Frank
