buffer for 1-Wire BUS ADG3301

Question

Hello, 
 I would need a buffer for an 1-Wire BUS. I find ADG3301. 
 1. I want to connect VCCA and VCCY both with 5V, what happens? On the first page I find: For proper operation, VCCA must always be less than VCCY. Is there a better alternative for my case? 
 I think the fastest signal is an 1us pulse. I want to connect max. 3 buffers in series. 
 Best regards, 
 Dirk Seidel

Hi Dirk, 
 I would recommend to have a look at the LTC4315 , a 2-Wire Bus Buffer with High Noise Margin for I2C interface. This might be suitable for your 5V to 3.3V level translation with buffers. 
 Let me know if this helps.
