Other Parts Discussed in Thread: TXS0206,
Dear *,
1) please can you tell us the difference between TXS0206A and TXS0206
2) which solution is better regarding EMI and ESD
a) TXS0206
b) TXS0206A + 2x TPD4E1U06DCKR
3) we see that the TXS0206 and TXS0206A has internal pull-up (40k) on all the DATA lines and CMD line
in some designs we saw that also CLK line has pull-up is it necessary to add external 40k pull-up on CLK line?
4) in order to use electrical card detect function on DAT3 line , it is suggested to use 270k pull-down on the line.
Do we have to add the 270k pull-down resistor on DAT3A and DAT3B side of the TXS0206 or TXS0206A?
5) Also the card has internal 50k pull-up on DAT3 which should be disconnected during regular data transmission with SET_CLR_CARD_DETECT command ACMD42
The TXS0206 or TXS0206A has pull-up on DAT3 line, is this ok ? Because when disconnect internal pull-up on DAT3 , there will be an pull-up in the TXS0206 or TXS0206A.
Best Regards,
David.
