LSF0102DCUR Descrizione generale

The LSF0102DCUR is a 2-bit voltage-level translator with dual supply voltage rails. It is capable of translating digital signals from one voltage level to another while ensuring signal integrity and avoiding voltage conflicts between the connected devices.

The LSF family of devices supports bidirectional voltage translation without the need forDIR pin which minimizes system effort (for PMBus, I2C, SMBus, etc.). TheLSF family of devices supports up to 100-MHz up translation and greater than 100-MHz downtranslation at ≤ 30pF cap load and up to 40-MHz up/down translation at 50pF cap load which allowsthe LSF family to support more consumer or telecom interfaces (MDIO or SDIO).

LSF family supports 5-V tolerance on I/O port which makes it compatible with TTL levelsin industrial and telecom applications. The LSF family is able to set up different voltagetranslation levels on each channel which makes it very flexible.

Bought for 123 p, sent in 2 days, received in the nsc in 44 days, the track to the place, at first thought it was good working that half the stroke of the regulator is not active, with 7 to 12 v increases norms without heating, good recommend
