FOR OPEN-DRAIN APPLICATION

DESCRIPTION

The UTC ULSF0102 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 ULSF0102 family to support more consumer or

telecom interfaces (MDIO or SDIO). The UTC ULSF0102 family

has bidirectional voltage translation without the need for DIR pin

which minimizes system effort (for PM Bus, I2C, or SM Bus).

The UTC ULSF0102 family supports 5V tolerance on I/O port

which makes it compatible with TTL levels in industrial and telecom

applications. The UTC ULSF0102 family is able to setup different

voltage translation levels on each channel which makes it very

flexible.
