The LSF family of devices supports bidirectional voltage translation without the need for DIR pin which minimizes system effort (for PMBus, I 2C, SMBus, and so forth). The LSF family of devices supports up to 100-MHz up translation and greater than 100-MHz down translation at ≤ 30 pF capacitive load and up to 40-MHz up or down translation at 50 pF capacitive load which allows the LSF family to support more consumer or telecom interfaces (MDIO or SDIO).

LSF family supports 5-V tolerance on I/O port which makes it compatible with TTL levels in industrial and telecom applications. The LSF family is able to set up different voltage translation levels on each channel which makes it very flexible.
