3 Description

The LSF family of devices supports bidirectional

voltage translation without the need for DIR pin which

etc.). The LSF family of devices 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).

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.
