LSF0102 (ACTIVE)

Dual Bidirectional Multi-Voltage Level Translator

 

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.
