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 which makes it very flexible.
