8 CHANNEL AUTO-BIDIRECTIONAL MULTI-VOLTAGE LEVEL TRANSLATOR FOR OPEN-DRAIN APPLICATION
DESCRIPTION
The UTC ULSF0108 family supports up to 100MHz up
translation and greater than 100MHz down translation at≤30pF
cap load and up to 40MHz up/down translation at 50pF cap load
which allows the UTC ULSF0108 family to support more
consumer or telecom interfaces (MDIO or SDIO). The UTC
ULSF0108 family has bidirectional voltage translation without the
need for DIR pin which minimizes system effort (for PM Bus, I2C,
or SM Bus).
The UTC ULSF0108 family supports 5V tolerance on I/O port
which makes it compatible with TTL levels in industrial and
telecom applications. The UTC ULSF0108 family is able to setup
different voltage translation levels on each channel which makes
it very flexible.
