Description

The PI4ULS5V108Q supports up to 100MHz up translation and greater than 100MHz down translation at ≤ 30pF cap load and up to 40MHz up/down translation at 50pF cap load which supports more consumer or telecom interfaces (MDIO or SDIO). It has bidirectional voltage translation without the need for DIR pin which minimizes system effort (for PMBus, I2C, or SMbus). 

The PI4ULS5V108Q supports 5V toleraance on IO port which makes it compatible with TTL levels in inductrial and telecom applications. It is able to set up different voltage translation levels on each channel which makes it very flexible.
