Other Parts Discussed in Thread: TXU0304
Hi team,
I have used this SN74GTL2003PW level translator in my design on a JTAG interface and found out that the JTAG link is very unstable. Below is my circuit diagram.
I have a few queries regarding this level translator. Please suggest
1) Do I need to have a Decap on SREF pin? is it mandatory for the proper functioning of the level translator? what happens if I do not place a Decap on SREF pin?
2) Is there a requirement for this level translator to have DREF side voltage higher than SREF side? or anything is fine like I can have SREF voltage higher than DREF side
3) Do I need to have pull-ups on SREF side also for the proper functioning of this device? or just the DREF side pull-ups fine?
Thanks
Santosh
