Part Number: SN74CBTLV3257
Whether all the IO pins are Open collector? Since i have seen in the CBT data book, ten(enable time) its mentioned as Open collector for the mentioned part number.
I have connected the JTAG signal with 1.8V in the A port and 2.5V in the B1 and B2 ports just need to know whether thats fine or i need to level shifter ?
Ashwin,
The SN74CBTLV3257 is a passive FET switch that will connect the input directly to the output. If you have two different voltage domains you will need to use a level shifter device maybe like the TXB0104.
Thank you,
Adam
