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
minimizes system effort (for PMBus, I2C, or SMbus).
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.
