Description

The PI4ULS5V108 supports up to 100 MHz up translation and greater than 100 MHz down translation at ≤ 30pF cap load and up to 40 MHz up/down translation at 50pF cap load which allows the LSF family to support 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 PI4ULS5V108 supports 5 V tolerance on IO port which makes it compatible with TTL levels in industrial and telecom applications. It is able to set up different voltage translation levels on each channel which makes it very flexible.
