Do You Even Need A Level Shifter? It might seem odd ... when you first have to ensure that different logic levels are safely interfaced. Will my 5V Arduino harm this 3.3V sensor?

For UART data level shifting, 74AVC4T245FT has four bidirectional level shift circuits in two pairs ... output-enable pins are within the ‘A’ side voltage domain and their logic levels are ~30% and ...

Low power high performance designs have become a recent trend in modern SoC design community. Often multiple voltage domains are being created in order to cater the need of low power requirements and ...
