Honored ContributorAuto-sensing voltage level shifters
I need to connect some 5V logic to FPGA devices that are not 5V tolerant. I checked different possibilites and found those "newer" auto-sensing dual-rail transcievers. Somebody have any experie...

Honored ContributorBe carefull with these, they don't look like ordanary buffers.
1. check the logic levels, its not TTL 2. they can not drive a lot of current (in the sense of a normal bus driver that does 20 - 40 mAmps). Look to the description of the working principle and schematic diagram at the end of the datasheet. Stefaan
