Hi Wei,
***********************************************************
I am suggesting the SN74LVCH8T245 to accomodate slow raise/fall time signals that the TXS0108E is not able to suport.
The input is from the power supply is more like a one-time status signal, i.e. it changes once in a while to indicate a PS failure. In theory if everything is good, this signal goes from low to high at power up and stays there until next power cycling. They don’t mind having a pulse as long as there are no endless oscillations.
The output goes to an FPGA that requires fast rise/fall times on its inputs.
- Input Signal rise/fall is slow – in the 30-40 micro-seconds range but it’s monotonous.
- The voltage translation is from (3.3V or 5V) to 1.8V
- Preferable 8-bit
- Open Drain
Please, advice if SN74LVCH8T245 cannot operate under those conditions, is there another part that we can suggest to the customer?
Thanks!!
