3 Description

LSF family 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 50

pF cap load which allows the LSF family to support

more consumer or telecom interfaces (MDIO or

SDIO). The LSF family has bidirectional voltage

translation without the need for DIR pin which

LSF family supports 5 V tolerance on IO 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.
