Bidirectional buffer with Better VOH and VOL
« on: April 25, 2019, 06:51:10 am »
Hi,

Buffer need to be placed between below two ICs. their noise margin levels are in negative. Please suggest me the bidirectional auto detection buffer or  level translator with which works on the below condition.

In my case, margin levels are,

Input IC's Vih min = 1.44V.
output IC's Vohh min= 1.40V and

input IC's Vil max= 0.36V

output IC's Vol max = 0.4V.

Thanks,
Vicky

To answer this question, we need to know the data rate and supply voltage(s) that are available.
